Replacing brake discs on a VAZ 2114 - step-by-step guide

Welcome! Brake discs - they are replaced in pairs and they must be installed identically (so that the manufacturer is the same) and after installation, when braking, the car will not pull to the side and the discs will wear out equally, at the moment there are a lot of underground companies that are engaged in the manufacture of counterfeit parts, The brake system is counterfeited very often and most often these are brake pads, so when purchasing parts related to the brake system, take into account everything from the availability of the box to the place where you purchased the auto parts.

Note! To replace the brake discs, you will need: Socket wrenches and wrenches, as well as a couple of screwdrivers and be sure to stock up on WD-40 fluid or some kind of penetrating lubricant like it, and you will also need to use tools to remove the wheels, such tools include a jack and a balloon wrench!

When should you change a brake disc? If mechanical damage appears on the disk (Mechanical damage includes chips, cracks and scuffs) or if the thickness of the disk is less than the minimum permissible thickness (And the minimum permissible thickness is 10.8 mm for a non-ventilated disk and 17 mm for a ventilated one), the thickness should be checked as in at least three places), then the disc must be replaced; if this is neglected, the disc may split in half or the pistons will be pushed out of the brake cylinders, and therefore the wheel will immediately stop braking, and if the pistons are pushed out and all the brake fluid will leak out , then the car will be left without brakes at all, so be careful and remove the wheels from time to time and check the thickness of the brake discs using a ruler.

Note! If chips, cracks and similar damage were found on the surface of the disc, but the thickness of the disc is even greater, then you can not change it, but turn it on a lathe, but only skilled people should do this, after turning, the thickness of the brake disc should not become less minimum acceptable, if this is the case, then the disk can be reused!

How to replace a brake disc on a VAZ 2113-VAZ 2115?

Note! Before changing discs (And you only need to change them in pairs, do not skimp on this, because this will lead to uneven braking and more force will be applied to the new disc, because of this, rapid wear will result and the need for an early replacement), think about buying brake pads, consult with a consultant, they will tell you which pads are best combined with these brake discs; if the pads were replaced recently, then you don’t have to change them to new ones!

1. First, jack up the car and remove the wheel from it, place stops (Rocks, shoes, etc.) under the rear wheels and apply penetrating lubricant to the pins that secure the brake disc (Indicated by red arrows), then take the key and unscrew the pins beyond their edges, they are unscrewed counterclockwise; if the pins suddenly become very acidic, then a hammer will help you, from the vibrations of which all the rust will fall off and the pins will unscrew without much effort.

2. Now you will need to remove the brake caliper from the disc, it would be more correct to do this from the very beginning, after removing the wheel, but even after turning out the pins, the disc will sit very well, just don’t make sudden movements (don’t pull the disc) so that it doesn’t flew off the hub, otherwise the brake hose that is connected to the caliper may break (You will find more detailed information on how to remove the brake caliper in the article entitled: “Replacing the caliper on a VAZ”).

Note! When the caliper is removed from the brake disc, you do not need to unscrew the brake hose from it and completely remove the caliper, because in this case all the brake fluid will leak out and the brake system will become airy, the easiest way to do this is this, or hang the caliper from the spring by a wire, only make sure that it does not fall down and the brake hose does not break, or the second option, place the caliper carefully on a lever of some kind and also make sure that it does not fall and most importantly, do not leave the caliper hanging purely on the brake hose, the hose may not withstand and tear, be careful!

3. Completion, grab the back side of the disk with your hands and remove it from the hub with sharp movements (If that doesn’t work, then gently tap the back side of the disk with a hammer in different places and it will come off the hub), sometimes the disk sticks to its seat and for it To remove it, you will need a hammer, you need to hit it with a hammer in the very center, as close as possible to the seat of the disk (see photo below), thereby the rust will disappear and it can be easily removed, if the disk is still used in the future, then in this case it will not damage replace it with a metal hammer, replace it with a rubber one, or just bring a spacer when you hit the brake disc.

4. The disc is installed in the reverse order, on the hub, or more precisely, on the seat where the brake disc sits, grease is smeared (Indicated by the arrow), but before applying it, using a metal brush, clean the seat from rust and dirt (This is mandatory) and then there will be no problems with installation, and if you ever decide to remove the brake disc, then thanks to the grease, there will be no special problems with removal.

Note! When everything is installed, at first avoid sharp braking, there is no need to check how the car will brake on new brake discs, because this can lead to their overheating, for the first time, for 250-300 kilometers, drive calmly, brake calmly, and in general, sharply We do not recommend braking, only in emergency cases, since heavily worn discs or discs made of weak metal (Fake) may crack, which will lead to their immediate replacement!

Additional video: On most cars, discs are changed completely identically, so look at the replacement process using the VAZ 2109 as an example.

Is it financially profitable?

When the owner of the car imagines how much work he has to do, willy-nilly he begins to calculate whether it makes sense to change the brake discs himself, or whether it is easier to take the car to a service station.

Depending on the manufacturer and the place where you purchase new brake discs, their price can range from 1 to 2 thousand rubles. Add to this minor expenses on consumables. Surely you have tools, a jack, and the same WD40 in your garage. That is, additional costs, in addition to the purchase of brake discs themselves, are minimal.

Now we invite you to familiarize yourself with the cost of services of professional service centers for the repair and replacement of various components of the brake system.

How to change brake discs on a VAZ 2114

Replacing brake discs on a VAZ 2114 is not such a complicated process; you can do it yourself. The only thing is that it takes a lot of time - 4-5 hours - but for those who love their car, it won’t seem like hard labor.

Replacing brake discs VAZ 2114

Usually, together with the brake units, they look at the condition of the pads, which they also try to change together with them. There may be a thousand and one reasons for replacement, but a special symptom indicating the replacement is in effect is the knocking (or beating) of the brake pedal when you actually brake.

The beating of the pedal is a kind of pranking, jolting. Feels good at high speed (during hard braking). If you suddenly decide that the brake discs will last a little longer, or wait for the fourteenth to simply stand up, you are making a big mistake! Such expectations will lead you straight to the emergency room.

If the pedal is acting up, there may be several reasons for the breakdown:

• The brake disc of the VAZ 2114 is warped - this is the most common fault. Such a misfortune happens to it due to temperature changes: sudden heating and cooling when braking, natural wear. The unit needs to be replaced, and it must be paired with another, even if the second one feels fine.
• The front pads may break, which also cannot be restored.
• Most often there are drum brakes at the rear (since it is front-wheel drive, it is not entirely reasonable to shell out for discs at the rear), and they fail.

It is important to understand that all manufacturers who make brake discs for the VAZ 2114 cannot guarantee a certain shelf life. Failure of an important part of the brake mechanism is almost always an unexpected situation. Their health directly depends on the quality of components and the quality of roads. The best thing you can do is to check their condition periodically.

Signs and causes of the problem

You can feel that the brake discs are already at the limit of their professional suitability by the beating of the pedal. She will, as they say, be naughty. This is easy to determine at high speeds when braking.

Don't think that "tired" disks will be able to work for some time. Such frivolity often leads to a hospital bed. And that's the best case scenario. We don’t want to scare anyone, but brakes are still an incredibly important safety system.

There may be several reasons why the pedal does not behave naturally.

1. The brake disc is deformed. This can happen due to temperature changes, sudden braking and normal wear and tear. If only one disk is damaged, the second one is replaced at the same time as the first. This is a rule that should be followed always and everywhere.
2. Broken front pads. It is impossible to restore their functionality, therefore they must be replaced.
3. The rear drums have failed. The VAZ 2114 has drums at the rear, although some install disc brakes. Think for yourself how justified such a decision is.

Checking the wear of discs and pads in the brake system

There are certain dimensions below which it is unacceptable to drive on existing brake units:

1. Brake disc thickness – 10.8 mm
2. Axial runout on the surface – 0.15 mm
3. Overlay on the block – 1.5 mm
4. Brake drum diameter – 201.5 mm

You cannot determine such dimensions by eye. Therefore, we jack up the fourteenth wheel, clean the entire unit from dirt, after removing the wheel, of course, and use a simple caliper to measure the thickness of the disc, pads and drum brake at the rear (if you have them). We compare all indicators with acceptable numbers.

Another important step is to check how the pads move: poke them with a screwdriver, if they move too hard, then they can clamp the disk, you need to change them, otherwise you will ruin them.

In general, it is good to remember the following parameters that require replacing the brake disc on a VAZ 2114:

1. Invalid thickness value (erased)
2. The pad linings are oily
3. There is a gap between the pads and the base
4. You hear a squeaking sound when you brake
5. Hit the brake pedal
6. If you have drum brakes at the rear, they can stick to the pads, which can lead to double replacement and expense.
7. The brake cylinders (front and rear) may become damaged - there is an option to revive them with a WD tool, but this will only temporarily delay the replacement

As soon as any of the above happens, the brake discs need to be replaced.

It also happens that all the main brake components have been changed, including the brake pads, but the situation has not changed for the better. Then look at the accompanying components and adjacent spare parts: hub bearing, front wheel arms (they are also called daisies). It is not necessary, but it is very advisable to do a wheel alignment.

Replacing disks

Now let's talk about how to change brake discs on a VAZ 2114. The removal and installation process are directly proportional to each other. The main thing in this whole event is to take into account the human factor - inattention. Remember what went where and check yourself carefully.

How to remove a brake disc:

• We place the car on a flat surface, having previously put the handbrake on
• Jack up and remove the wheel
• Loosen the brake cylinder fasteners
• Use a screwdriver to pry out the boot from the upper guide of the brake pad
• We remove the pads and caliper (for the caliper you will need a 17mm wrench; before unscrewing it, you need to remove the brake hose fasteners. But the pads are a separate matter, if you don’t know how to remove them, there is a separate material for enlightenment)
• To prevent the brake fluid from escaping, place a container under the hose (when you put everything back together, don’t forget to add the leaked fluid back into place!)
• Next, we do some general cleaning - we remove dirt and traces of rust on the surface of the brake disc (don’t even think about scratching its working surface!)
• Then everything needs to be treated with WD (pay special attention to the hub bearing)
• Using a size 8 wrench, you need to unscrew all the wheel pins, but the disk should not turn during this action.
• Before removing the disk itself, knock on it (knock on the plane, not on the working surface)
• Let's take it off.

As already mentioned, we put everything in reverse order. The main thing is that before installing all parts of the brake system, lubricate the hub itself, and the working surface of the disc must be lubricated with a special product that will degrease it. Another point, if you have replaced the brake cylinders, you must bleed the brake pedal.

Front wheel brake

Removal and installation

Withdrawal. Raise the front of the car and place it on stands and remove the wheel. Unscrew the pipeline fitting and disconnect the flexible hose from the line; Plug the holes in the hose and tube to prevent brake fluid from leaking. Remove the hose from the guide bracket.

After unscrewing the two bolts that secure the shoe guide to the steering knuckle, remove the guide assembly with the caliper and working cylinder.

Installation of the brake mechanism is carried out in the reverse order of removal. After installation, restore the brake fluid level in the reservoir and bleed the hydraulic drive system to remove air.

Price

If we talk about the current price of VAZ 2114 brake discs, then we need to estimate the region of the country. On average, from 1000 to 2000 rubles. Having found out how much brake discs cost on a VAZ 2114, it would be logical to take into account the average cost of installing them, as well as a summary of prices for installing components (by the way, do not forget a simple regularity: installing a spare part on the fourteenth is almost always equal to or slightly less than the cost of the spare part itself parts). This understanding will be the most justified argument to figure it out yourself and save money.

Service professionals are ready to take on work at the following prices (on average):

• Removing and installing a brake drum - from 300 rubles
• Removing and installing rear brake disc – from 800 rubles
• Removing and installing the front brake disc – from 1000 rubles (they change it more often, that’s where the cost comes from)
• Replacement of drum pads – from 800 rubles
• Replacement of disc pads – from 500 rubles

What are the best brake discs for a VAZ 2114?

A properly functioning car brake system is the key to safety and good maneuverability on the road.

Despite the relative simplicity of the design of the VAZ-2114, the unit requires systematic care and maintenance. Scheduled technical inspections will help prevent sudden breakdowns and defects.

The repair process is not at all complicated; the task is within the driver’s power. There is no need for special equipment or tools, a standard set is enough. If you don’t have time for self-prevention, visit a service station to order services and comprehensive diagnostics.

What front brake discs can be installed on a VAZ 2114

In cars of the VAZ family of most modifications, the front braking system is presented in the form of disc brakes. By default, the VAZ-2114 is equipped with domestic components, but their quality does not always satisfy the requirements of motorists. Some use spare parts from foreign manufacturers.

The average service life of brake pads does not exceed 30 - 40 thousand km, discs 75 - 85 thousand km.
