Replacing the front and rear brake cylinders on a VAZ 2110

If you begin to notice rattling of the calipers on your car, then first of all you should pay attention to two things:

1. On brake pad springs that may have weakened.
2. On the caliper guide pins - they may have worn out due to lack of lubrication.

This article will consider the second option, when it is the wear of the guide pins that leads to similar problems. First of all, you should pay attention to the condition of the anthers. If they are torn or even cracked, they must be replaced with new ones, and the fingers themselves must be re-lubricated. But more on this below.

Necessary tool for inspecting calipers on VAZ 2110, 2111 and 2112:

• flat blade screwdriver;
• wrench for 13 and 17 mm;
• copper grease;
• lubricant for caliper guide pins;
• brake cleaner.

Major breakdowns

The front caliper of the VAZ-2110 is a structural element that holds the brake pads and is responsible for the level of pressure of these elements on the metal discs.
It also helps ensure even pad wear, which guarantees effective braking in any situation. The body is made of aluminum alloy and the piston is made of steel. Between these elements there is an oil seal that prevents brake fluid from leaking out of the system. The main caliper breakdowns are as follows:

1. The appearance of oxidation on the surface of the guide elements.
2. Oxidation on the main piston, which leads to deterioration of the mechanism.

Failure can be identified by uneven wear of the pads, as well as by an increased braking distance. If such malfunctions are detected, be sure to change the pads.

Main causes of malfunction

The VAZ 2110 caliper is structurally an element that holds the brake pads and is responsible for the degree of their pressure on the brake discs. It is also responsible for uniform wear of the brake pads and guarantees the driver reliable braking in extreme situations.

Thus, the importance of the caliper in the operation of the car is difficult to overestimate

If by this time you have a completely reasonable question, what can happen to the caliper on a VAZ 2110 (2112), we will be happy to answer you. The main cause of malfunctions is “acidification” of the moving elements, coating them with an oxide film, clogging due to the destruction of protective boots or the use of improper lubricant, namely:

• acidification of the main piston mechanism;
• acidification of guides.

Piston mechanism and caliper guides VAZ 2110

A clear sign of problems that the caliper can cause on VAZ cars is uneven wear of the brake pads and an increased braking distance. In this case, the VAZ pads must be changed, and the caliper mechanism itself must be subjected to comprehensive diagnostics:

• check the condition of the piston, its degree of freedom, the presence of moisture, metal oxide, oxide formations and build-ups, the condition of the protective boots;
• Similarly, check the condition of the guides, make sure that there are no uncharacteristic scuffs, abrasions or deformations of the rod on the surface.

We must also not forget about regularly replacing the brake fluid in the system. This should be done approximately every 40 thousand km. mileage of VAZ-2110.

Since brake fluid is hygroscopic, it easily absorbs moisture, thereby oxidizing the piston mechanism and causing it to fail. The piston stroke becomes difficult and uneven wear of the brake pads and wheel wedge occurs.

Brake fluid

Any brake fluid that is used in automotive systems absorbs moisture very well. It is hygroscopic, therefore it oxidizes the piston mechanism from the inside, which leads to failure of structural elements. This makes the piston stroke more difficult and the brake pads wear unevenly.

The front wheels may become jammed. For these reasons, it is necessary to replace the brake fluid. Its service life is about 90,000 km, but not more than two years. These solutions contain many useful additives that improve cooling and increase braking efficiency.

But over time, under the influence of high temperatures and pressure, these additives evaporate. And the consistency of the brake fluid becomes more like water, and this reduces the efficiency of the system.

Repair kits

You can purchase special kits designed for caliper repair. But there is no point in purchasing it. It is much better to replace the VAZ-2110 caliper. In this case, you will increase the life of the entire braking system and also improve its reliability. Such repair kits contain the lubricant that is necessary for the piston and guides.

You cannot use graphite lubricant such as CV joint or Litol-24, as this will cause the protective shock absorbers to swell and the guides to simply oxidize. As a result, repairs will not bring the desired effect for a long time.

Calipers for VAZ 2110: repair and maintenance

Have you ever wondered what exactly your safety on the road depends on? You can, of course, refer to other road users or the condition of the roads. But it will be much more relevant to talk about the technical side of the issue. The hero of our today's article on the VAZ 2110 is the caliper.

Front brake cylinder VAZ 2110

An incredibly simple mechanism in design and operation, at the same time it is an extremely important part of your VAZ car. A properly functioning caliper can give you those precious few meters of braking distance in reserve, which can protect you from a terrible disaster or damage to your vehicle.

Not every motorist knows how to properly monitor and maintain the brake mechanism, has a vague idea of ​​how to dismantle it and, perhaps, will generally look at his interlocutor with a blank look when mentioning a certain VAZ caliper. But servicing this element of the brake system is quite simple and does not require much effort.

VAZ 2110 caliper maintenance

On the road you should not rely on the Almighty. Therefore, if you feel that something is wrong with the braking distance of the car, it is better to take the initiative into your own hands. Arm yourself with a modest arsenal of locksmith tools, consisting of a small number of open-end and socket wrenches, as well as a certain amount of theoretical knowledge - get down to business.

Do-it-yourself dismantling of the caliper on a VAZ-2110

The very simple design of the product and the triviality of the process of dismantling it allow even a novice motorist to carry out repairs and maintenance. If you carefully follow the recommendations below, you are unlikely to encounter difficulties at any stage of the process. You will save a lot of money spent on a trip to a service station, and a considerable amount of time, because the service time is comparable to the time required to travel to the workshop.

Dismantling VAZ caliper

The sequence for dismantling the product is as follows:

1. The first step is to jack up the car and remove the wheel. To be on the safe side, it can then be placed under the bottom of the car in case the jack fails;

1. On a VAZ 2112, the caliper is attached to the bracket using two M17 bolts, which you should unscrew. Penetrating lubricant may be needed to strip the bolts;

1. If you need to replace the VAZ caliper or carry out a comprehensive repair, unscrew the product from the brake hose. You seal the hose tip and you can begin further disassembling the product.

Diagnostics

To check the front brake caliper of the VAZ-2110, you will need to perform the following steps:

1. Assess the condition of the metal piston and the ease of its movement inside the cylinder.
2. Check for metal oxidation, oxide formations or build-ups, or moisture on the elements.
3. Assess the condition of all rubber boots.
4. Check the condition of the VAZ-2110 caliper guides. You must make sure that there is no abrasion, deformation or scuffing on their surface.

Any damage to the caliper body and its and other elements should alert the driver. In this case, it is necessary to change the mechanism.

Guide faulty

The main problem if the brake does not work can be jamming and souring of the caliper guides.

Repairing this malfunction with your own hands will not be difficult. By the way, in this case there is no difference when disassembling both the front and rear calipers. To do this, you need to unscrew and pull out both guides. Clean them from dirt or poor-quality lubricant, remove and replace the torn boots with new ones, after filling them with special grease for calipers.

Then put them in place, insert and screw the guides back. Then you should try how freely the pressure bar moves along them. This can be seen visually in the attached video at the end of the article.

We should not forget about the housing of this brake element. If significant rust, dents, sagging or other mechanical damage is found on it, it should be replaced completely.

If the repair had to be done on a removed caliper, then after installing it in place, the brake system should be bled.

Detailing

Assembly elements on the front brake mechanism:

• Dustproof cover;
• Pad holder;
• Noise protection gasket and spring;
• Two pads: internal, with a wear indicator, and external;
• Fastening plates;
• Cylinder cover and piston;
• Caliper;
• Bracket;
• Air release valve;
• Gasket, bushing, pin, seal.

For the tenth to twelfth VAZ models, these units are structurally the same, only the VAZ 2110 caliper bracket is different. Therefore, it becomes possible to install not only the “native” unit, but also from “related” models. Naturally, this requires replacing the bracket itself.

It plays a vital role in securing the caliper and brake mechanism, and also forms the front clamping mechanism along with the caliper, piston and caliper.

Thus, the bracket is not only a holding element, but also a guiding element of the front wheel locking mechanism.

Front caliper parts

Naturally, when it fails, the entire assembly is often replaced, but individual elements can be repaired, for which there are special repair kits.

The price of a repair kit averages about 500 rubles and includes:

• 1 hose fitting with cap;
• 2 protective covers for guides;
• 1 O-ring;
• 1 caliper protective ring.

The price of a new left or right front caliper fluctuates around 1000-1500 rubles.

VAZ-2110 caliper maintenance and repairs

It is mandatory to service the VAZ caliper after each replacement of brake pads, as well as in the event of a forced inspection due to its malfunction, for which it is first necessary to check the condition of all rubber elements, shock absorbers and anthers. It is also imperative to replace the grease for the caliper guides. You need a good synthetic based silicone lubricant that can withstand high temperatures.

To remove the piston from its seat, it is necessary to create the appropriate force using an air compressor (pistons are repaired one at a time, the stroke of the second is blocked, for example, by a wooden block). With the same success, when removing the product from the car, you can press the brake pedal without disconnecting the VAZ 2112 caliper from the brake hose. It is advisable to use a rubber adapter in order to absorb the sharp impact of the freely moving piston and its “shot”.

VAZ 2110 caliper repair

The piston is pushed back using a special clamp. In this case, the boot should be bent to compensate for excess air pressure. The hole for the piston and for the guides are cleaned and washed with carburetor cleaning fluid, all gaskets, boots and seats are also thoroughly lubricated.

Causes of jamming and creaking

Now directly about how to determine the presence of a problem.

The primary sign indicating a malfunction in the calipers of a car brake system is squeaking.

How to restore rights if lost: choose the quick method

It is the creaking that indicates that the element is seriously worn out. In the near future, the unit must be replaced without fail, which the car literally and figuratively screams about. It is extremely difficult not to hear such a creak. But for some reason, thousands of motorists still stubbornly ignore it. As a result, they pay a rather high price. Sometimes even to the point of road accidents resulting from brake failure while driving. To prevent this, you need to understand the issue and understand the essence of what is happening.

The first step is to look at the possible causes. In fact, there are several potential problems to look for. Some of them arise due to the fault of the motorist, others are caused by the natural process of wear and tear.

In any case, the appearance of a squeak as a symptom is a harbinger that at the most inopportune moment the caliper may simply jam.

If you know the reasons, you can prevent them and troubleshoot them by contacting a car service center or solving the problem yourself.

The reasons are:

• The brake pads were initially installed incorrectly. As a result, they are not strictly parallel to the response drives. Because of this, creaking often appears;
• The brake discs are seriously worn out. The reasons are natural wear and tear and aggressive use of the car;
• There is no lubrication in the unit. Initially there was little of it, or it was used up;
• The lubricant was selected incorrectly. Many people skimp on lubricant intended for calipers, hence the consequences.

The most undesirable and dangerous situation is rightly considered when the piston does not return and the unit begins to jam during operation.

Imagine that you are driving a car, press the brake, and then accelerate again. But at the same time, the calipers do not release the front brakes. Additional resistance arises, the car tries to move, but cannot. The result is uncontrolled braking, extremely intense wear and serious overheating of the entire system.

The procedure for removing the caliper and video instructions using the example of a VAZ 2110

So, let's look at the order of actions that need to be performed.

• Raise the car with a jack
• Remove the front wheel
• Disconnect the brake hose from the front strut.
• Unscrew the two caliper mounting bolts from the inside

See the step-by-step instructions using the example of the VAZ 2110, which was made specifically for this article:

As you can see, this process can be completed in 5 minutes, the name of the necessary tool is at hand and an idea of ​​​​all the necessary actions. A new caliper complete with brake pads has a price of 2,000 rubles for original AvtoVAZ products. If we consider cheaper analogues, then you can buy a caliper for 1,500 rubles - a piece.

Of course, in most cases it is necessary to change only the necessary spare parts of this entire structure, because the cylinder, bracket and pads are sold separately. And for many car owners it simply doesn’t make sense to buy the whole thing assembled.

Procedure for replacing the front brake cylinder on a VAZ 2110-2112

Video instruction

The video was made using the example of a VAZ 2110 car and is equally suitable for both 2111 and 2112. The only way the car parts may differ externally is the brake discs: ventilated or not, as well as their sizes.

Photo report

First of all, we will need to remove the front wheel of the car, after first lifting the car with a jack. After this, using a hexagon, you need to unscrew the two bolts securing the caliper bracket.

Now you can remove the bracket and remove the pads:

Then you can rip off the brake hose with a wrench, but you don’t have to unscrew it completely.

Next, we unscrew two more bolts securing the cylinder to the caliper, having previously bent the two locking plates under them using a screwdriver.

And we move the cylinder to the side, since nothing else holds it.

The hose can now be unscrewed completely by turning the brake cylinder itself several times counterclockwise.

To avoid excessive losses of brake fluid, it is advisable to fix the hose as high as possible, and always with the fitting facing up. You can also substitute a container if liquid suddenly leaks out.

A new front one costs about 500 rubles, so this price is quite acceptable. But the assembled caliper already costs about 2,000 rubles, which is already significant if you suddenly have to change the entire assembly. Installation of this part occurs in the reverse order.

Checking the caliper and restoring it

The caliper is installed on the front and rear brakes. Its verification and restoration can be carried out independently, but, in the absence of the necessary practical skills and theoretical knowledge, it is best to turn to professional specialists. Let's consider in theory a method for checking and restoring a caliper on a VAZ 2110, the price of which is one of the lowest on the market.

The main task comes down to properly disassembling the caliper, cleaning it of old grease residues, applying a new special compound and checking the integrity of the rubber seals. First you need to gain free access to the front brake mechanism, which is located directly behind the wheel. For these purposes, supports are installed that help to easily and quickly remove the wheel.

After this, they begin the process of replacing the brake pads on the front caliper of the VAZ 2110. To do this, you need to remove the lower bolt, which is responsible for fastening the caliper, using a screwdriver, the body of which can easily be tilted up. When replacing old brake pads, you should remember their location, since the installation of new parts should be carried out in the same place.

If the VAZ 2110 caliper body was folded up and the brake pads were removed, then you can proceed to the next stage. In this process, you will need to unscrew the upper bolt responsible for fastening the caliper. It is worth noting that the line and brake fluid must remain connected.

Next, the bolts that serve to connect the knuckle and caliper bracket are unscrewed. After removing the bolts, you can remove the bracket (along with the brake pad clamps and guides). Subsequently, the piston is removed from the caliper body. It can be quite difficult to do this yourself, so you can use the services of professional auto repairmen working at service stations.

If you decided to check and restore the VAZ 2110 caliper yourself from start to finish, then you can try to carry out the following steps:

• conveniently position the caliper body without disconnecting it from the brake line.
• press the brake pedal and release it only when the piston is pressed out of the cylinder by the pressure.

Do not be alarmed if liquid suddenly leaks from the cylinder, as this is quite normal for removing the piston using the above method. Next, you need to interrupt the brake line connection and also plug it (to prevent further fluid leakage). Once the so-called “blockage” has been established, the process of disassembling the “tens” caliper can be considered successfully completed.

It is worth considering the fact that the above steps do not cover the replacement and reassembly of the brake system. But, based on their complexity in describing the initial stage, one can understand how complex a part the caliper is.

Types of installed calipers and their prices

The same caliper is installed on a given family of cars, with the exception of the index in its marking, indicating the model of the vehicle body. Otherwise, these are identical brake devices that have a single-piston design independent of the fixed caliper. A similar modernization took place after 2001, and the last half calipers with 4 pistons were installed on the VAZ 2108.

The cost of a caliper for a VAZ 2109, 2110, 2114, 2115 can be as follows, based on its condition:

• New – 1,610-4,270 rub.
• Used – 700-1,980 rub.
• Refurbished (restoration using original components) – 1,420-2,190 rubles.

Do-it-yourself dismantling of the caliper on a VAZ-2110

If you carefully follow the recommendations below, you are unlikely to encounter difficulties at any stage of the process.

Developing a brake caliper piston | Twokarburators.ru

The brake mechanisms (calipers) of the front wheels of VAZ 2108, 2109, 21099 vehicles operate under constant exposure to an external aggressive environment (salt, dirt, water, etc.).
In this regard, it is recommended to inspect and service calipers and brake pads every 15 thousand km. Jamming or “souring” of the pistons in the caliper cylinders is most often the result of a lack of periodic monitoring of the condition of the brake mechanisms, damage to their protective boots, severe wear of the brake pads in which the pistons extend too far from the cylinders, thereby coming under external influence, the presence of water or foreign substances. impurities in brake fluid. Damage to the mirror coating of the pistons (“souring”) leads to a loss of their mobility in the cylinders and, as a consequence, to incomplete release of the front wheels, since the pads are constantly pressed against the brake discs. In this case, accelerated wear of the pads, overheating and warping of the brake discs occurs, fuel consumption increases, the vehicle's controllability (pulls to the side) and its dynamics are impaired, vibration and beating appear when the brake pedal is pressed.

There are at least two ways to develop a soured piston:

— without removing the brake mechanism from the car;

- with the brake mechanism removed.

In the first case, it is necessary to jack up the car, remove the wheel, clean the outside of the caliper from dirt, disconnect and lift its floating bracket.

We remove the retaining ring and the cylinder boot, remove dirt from under it using a rag soaked in gasoline and a hard brush or toothbrush. Lightly press the brake pedal so that the piston moves out a little (a centimeter at most) from the cylinder. We clean it again, being careful not to damage the piston mirror and remove only dirt and deposits. You cannot clean the piston with sandpaper, as this can damage the mirror. A popular way to clean deposits is to use a rough wooden block, which will remove deposits and not damage the cylinder. Remove the cap from the brake fluid reservoir and, using an adjustable wrench or vice, push the piston back into the cylinder. We press the brake pedal, pushing out the piston, and press it down again. We carry out this procedure for developing his mobility 20-30 times. Then we apply graphite lubricant to the protruding part of the piston, install a new boot and retaining ring.

The advantage of this method is that there is no need to drain the brake fluid from the car’s brake system circuits and pump the brakes.

In the second case, we remove the brake cylinder and disassemble and develop it. This method is suitable for a major overhaul of calipers, since it is necessary to either drain the brake fluid or plug the brake pipe, which still risks losing a certain amount of fluid and requires bleeding the brakes after the work is completed.

The piston must be squeezed out of the cylinder either before removing it (by pressing the brake pedal), or with the piston already removed, pressurized air must be supplied into the hole under the brake pipe. Before extruding, remove the retaining ring and boot from the piston. We try not to scratch the removed piston. We clean it from dirt and oxidation using the method described above, if necessary, change the rubber sealing ring, rinse and blow through the cylinder. Before assembly, lubricate the inside of the brake cylinder with brake fluid, and lubricate the piston itself with graphite lubricant. We press it inside the cylinder (for example, using a vice), put a new boot and retaining ring on top.

All of the above manipulations make sense only if there is minor damage to the piston or cylinder. If the piston is completely jammed and it is impossible to develop it, the brake cylinder with the piston should be replaced. Notes and additions

— After developing the pistons of the brake cylinders of the front wheels of the car, it is necessary to lubricate the guide pins.

Replacing brake caliper guides for VAZ 2110, 2111, 2112

Lately, there has been a grinding noise when braking. An inspection of the brake system showed that the discs and pads were in good condition.

One of the reasons for grinding and rattling of calipers may be worn guides. Also, worn guides can lead to uneven wear of the pads (when one of the pads wears out faster than the other). This is exactly the wear that was on the old pads when they were last replaced.

Inspection of the guides showed that they are not jammed, but the lubricant has coked and thickened, and there is also noticeable play.

4 guides were purchased along with anthers, the price was 40 rubles per piece. And also a special lubricant for brake systems BOSCH SUPEFIT (5000000151) for 50 rubles. One bag is just enough for four guides.

It is important to know that not any high temperature grease will work for caliper guides. Do not use ceramic grease or copper-based grease. These lubricants coke and cause the guides to jam.

They can also be aggressive towards anthers. As it turned out later, BOSCH lubricant is not suitable for guides; the temperature range is only -25°C +130°C, which is naturally not enough for this unit. Although the manufacturer claims that this lubricant is universal and is exactly suitable for guides. I found supporting information in the official brochure about the use of lubricant

These lubricants coke and cause the guides to jam. They can also be aggressive towards anthers. As it turned out later, BOSCH lubricant is not suitable for guides; the temperature range is only -25°C +130°C, which is naturally not enough for this unit. Although the manufacturer claims that this lubricant is universal and is exactly suitable for guides. I found supporting information in the official brochure about the use of lubricant.

We'll ride it for now, and we'll see.

Before replacing the guides, remove old grease and thoroughly wash the bracket. To remove the old grease I used 646 solvent.

Its disadvantage is that it is aggressive to the rubber from which the anthers are made, so after using the solvent, I washed the staples with a degreaser. New lubricant should be applied in a thin layer.

The boots on the new guides turned out to be complete crap, several tore at once, so I had to install the old ones, which turned out to be in good condition. By the way, when assembling, you should first put the boot on the bracket, and then on the guide. This makes it much easier and less likely to tear the boot.

After replacing the guides, the grinding noise when braking no longer bothers me.

Installation of calipers from Volga on VAZ 2110

Brakes GAZ 3110 and VAZ 2110, what is the difference?

The negative aspect of switching to more massive calipers from the Volga is in weight. For example, the weight of a VAZ caliper with pads is 3.2 kg, and the weight of a Volga caliper with pads and adapter is 5 kg. That is, by replacing the standard 'tens' calipers with Volgov calipers, we increase the amount of unsprung mass of the car.

The positive aspect of the Volga brakes is that the large pad area allows for better heat dissipation. Car enthusiasts also note their better efficiency compared to standard VAZ 2110 brakes.

Adapter for GAZ 3110 caliper for VAZ with front-wheel drive

Drawing of an adapter for the Volga caliper for VAZ 2108/2110/1118/2170 (AutoCAD format)

In the archive there is an adapter for brake discs R14 and R15, archive password: lada2111rf

Gas 3110 from storage. Automobile equipment surplus, used sale.nelikvidi.com

Installation of calipers from GAZ 3110 to VAZ 2110 (R15)

You will need: Volga calipers along with pads, an adapter for Volga calipers on a front-wheel drive VAZ (2 pcs), caliper hoses from a Chevrolet Niva (short).

Remove the caliper along with the bracket, and then disconnect the hose from the tube. Drill out the hole in the bracket on the body that holds the connection between the hose and the tube. This is done in order to thread the hose fitting. Connect one end of the hose to the tube. The other end is with a caliper.

Next, screw the adapter to the guide of the GAZ 3110 pads using M12x25 bolts with a pitch of 1.25 (it is advisable to use bolts with the letter 'X') and M12 bolts. Then screw the adapter with the guide to the steering knuckle using standard M10x25 bolts, pitch 1.25. Install the Volga pads, having previously cut off the wear sensor wires from them. Install the caliper. The bleeding fitting must be at the top, otherwise it is impossible to bleed the brakes. All that remains is to bleed the brakes, and here it is worth considering that with GAS calipers, more brake fluid is poured into the system.

Installation of calipers from GAZ 3110 to VAZ 2110 (R14)

In general, the installation is similar, but there are a number of points that are worth paying attention to: 1. Due to the fact that when installing R14 brake discs, the guide will move towards the steering knuckle, so we saw off the edges of the boot using a grinder. 2

The adapter is used for R14 brake discs. Bolts should be used 5mm shorter, M10x20 pitch 1.25 with an M10 lock washer. Otherwise, the bolt will press the adapter to the brake disc and the disc will not turn

2. The adapter is used for R14 brake discs. Bolts should be used 5mm shorter, M10x20 pitch 1.25 with an M10 lock washer. Otherwise, the bolt will press the adapter against the brake disc and the disc will not turn.

3. The Volga’s caliper is larger than that of the “ten”, so you have to install a disc with a different offset, in this case the ET35 offset. An 11mm spacer for the wheel rim is also used. When installing disks, the seat may cling to the disk guide; in this case, you can grind the guide or use a spacer of the required thickness.

Conclusion

The negative point, which is the large weight, in practice does not affect the behavior of the machine. And the performance of brakes with GAZ calipers is significantly better.

By the way, this is not the only way to tune the brakes; rear disc brakes are very popular, as well as simply replacing brake discs from R14 to R15.

How to remove and disassemble a VAZ caliper

To dismantle the caliper, you need to hang the car on a jack and remove the front wheel. Then unscrew the nut connecting the flexible hose of the brake system to the brass tube. Brake fluid will leak from the front circuit, so you should prepare a container for it in advance.

Using a 17 mm socket wrench or a socket wrench, unscrew the bolts that secure the caliper to the steering knuckle. They are located on the inside and are located next to the grenade boot.

Then, by sliding up the brake rotor, the caliper can be completely removed. The remaining disassembly work is carried out in a vice. If they are not available, then disassembly is carried out right on the spot, without disconnecting the caliper from the steering knuckle.

Caliper repair

If you decide not to replace, but to repair the mechanism, then you can purchase a special kit for this purpose. It consists of the following components:

1. Gaskets.
2. New piston.
3. Guide elements.

The cost of the repair kit is about 500 rubles. And a new caliper for a car of the tenth family, depending on the greed of the seller, may cost 2-3 times higher.

But before installing the new elements that are included in the kit, it is necessary to completely disassemble the VAZ-2110 caliper. To do this you will need to use an air compressor. Connect it to the hole for the brake pipe, and then gradually supply air. It is advisable to install a rubber spacer or a wooden block under the piston. This will avoid a shot, since the piston moves freely.

A similar action can be performed immediately before removing the mechanism. To do this, you do not need to disconnect the caliper from the system; instead of the brake pads, install a small wooden block. Gently press the brake pedal to build up pressure in the system. In this case, you will lose some amount of liquid, but if you were planning to fill in a new one anyway, then this is not a problem.

Installation of a new piston is done using a clamp. Be sure to bend back the boot to avoid damaging it. Before installing the piston, it is necessary to remove contaminants on the internal surfaces with non-aggressive liquids. It is not recommended to use liquid to clean the carburetor, as it can damage rubber and plastic products.

Installing a new caliper

Installation of the device is carried out in the reverse order. To do this you need to do the following:

1. Install the brake caliper housing and tighten the mounting bolts.
2. Tighten the bolts using a 17mm wrench.
3. Push back the locking plate and unscrew the bolt with a 13mm wrench to remove half of the caliper.
4. The piston must be completely pressed inside the mechanism and new brake pads must be installed.
5. Reinstall the caliper half and tighten the nut. Bend the locking plate using a chisel.
6. Screw on the brake hose.
7. Bleed the entire system to get rid of any air in it.

After bleeding the system, it is imperative to put rubber plugs on the fittings. With their help, these elements are protected from moisture and dust. And the next time you pump, unscrewing the fittings will be much easier.

Repair

The first rule: if you don’t want further troubles, especially when one of the wheels jams, never repair only one caliper, always both together!

To sort through, repair or replace individual parts, and possibly completely change the unit if it turns out that there is nothing left to repair, you need to follow the following algorithm:

Remove the ring securing the cover, and then the cover itself; To avoid damaging anything, place a piece of wood or a rag between the caliper and the piston, then remove the piston

Also watch your fingers - parts of the mechanism can press them; After removal, pay attention to the piston and cylinder. If you find any damage on them, then the entire assembly needs to be replaced; If everything is fine, using a wooden or possibly a plastic tool, remove the piston seal from the caliper cylinder; If you have a PD51 model, you need to squeeze out the bushing, remove the covers protecting from dust on both sides; All elements should be washed with a liquid intended specifically for cleaning brake mechanisms; You probably purchased a repair kit

From this, “push” a new seal onto the piston, then place it in the cylinder. This must be done without using brute force, otherwise the brake mechanism may subsequently jam; Install the piston dust cover - a new one, from the repair kit; The bushings must be lubricated with silicone grease, which is also included in the repair kit, then installed in the corresponding holes; Install the dust covers in their proper places; Before installing the caliper on the car, replace the copper gaskets on the hose connection.

The front brakes can now be completely reassembled. A prerequisite after repair is to bleed the brakes.

All that remains is to check whether the wheels lock properly when you press the brake pedal, and whether the caliper is sticking. Everything is fine? So, you can hit the road.

Dust resulting from brake pad wear contains asbestos, which is hazardous to health. Do not blow it out with compressed air or inhale it.

If it is necessary to rebuild the caliper (usually due to a brake fluid leak), first find out the price of spare parts or the cost of an already rebuilt or new caliper. Before you start rebuilding, purchase a repair kit. Always repair both calipers together - never repair just one of them.

VAZ-2110 caliper maintenance and repairs

It is mandatory to service the VAZ caliper after each replacement of brake pads, as well as in the event of a forced inspection due to its malfunction, for which it is first necessary to check the condition of all rubber elements, shock absorbers and anthers. It is also imperative to replace the grease for the caliper guides. You need a good synthetic based silicone lubricant that can withstand high temperatures.

If you had to buy a repair kit, it contains such lubricant, all the necessary gaskets, new guides and a piston. The price of such pleasure will cost you about 500 rubles. Buying a new VAZ-2110 (2112) caliper, depending on the store and region of Russia, will cost from 1000 to 1500 rubles.

To remove the piston from its seat, it is necessary to create the appropriate force using an air compressor (pistons are repaired one at a time, the stroke of the second is blocked, for example, by a wooden block). With the same success, when removing the product from the car, you can press the brake pedal without disconnecting the VAZ 2112 caliper from the brake hose. It is advisable to use a rubber adapter in order to absorb the sharp impact of the freely moving piston and its “shot”.

VAZ 2110 caliper repair

The piston is pushed back using a special clamp. In this case, the boot should be bent to compensate for excess air pressure. The hole for the piston and for the guides are cleaned and washed with carburetor cleaning fluid, all gaskets, boots and seats are also thoroughly lubricated.

Where and how to buy?

You can buy a caliper at any auto store that specializes in selling components for domestically produced cars. As a rule, in such stores all goods are in stock. You can select a suitable caliper either by writing out its markings, or rather the final index of the last 5 digits, or by providing the seller with a faulty caliper (the weight of the product is only 2.17 kg ). Approximately once every 3 years, the suspension of cars of the 2109-2115 family was updated, therefore, the location of the mating threaded seats (mounting bolts) may vary slightly.

New ventilated brake discs are compatible with all mentioned calipers for VAZ 2109, 2110, 2114, 2115. The installation is fully consistent with original components.

Removing the caliper

The mechanism is of a very simple design; dismantling can be done without much difficulty. Even a novice motorist can cope with such work. In order to remove the VAZ-2110 caliper, you will need to perform the following steps:

1. Loosen the wheel bolts on the side being repaired.
2. Raise the side to be repaired using a jack and remove the wheel completely. Install it under the bottom of the car. This will protect you in case the car suddenly falls off the jack.
3. Cars of the tenth family have the caliper attached to the bracket using two M17 bolts. They need to be unscrewed. If you can't strip the threads, use a penetrating lubricant.
4. Unscrew the brake hose, which is located at the top of the caliper.

When dismantling, evaluate the condition of all rubber tubes. If there is damage on them, even small cracks, it is imperative to install new elements. Such breakdowns can lead to the brake system depressurizing while driving.

Installing the brake caliper

Installation of the brake caliper on the VAZ 2107 is carried out in the reverse order of its dismantling.

After installing the brake caliper, it is imperative to bleed the brake system, removing air from it. Until this operation is completed, operating the vehicle is strictly prohibited.

The left and right wheel calipers are slightly different, so you need to pay attention to this when purchasing new ones. After repairing and installing the VAZ 2107 brake caliper, it is necessary to check the brake system for fluid leaks and, if necessary, repair them
