Setting the brake pressure regulator VAZ 2109

adjusting the brake pressure regulator drive on VAZ 2108, VAZ 2109, VAZ 21099 cars

Improper adjustment of the brake pressure regulator drive can cause the vehicle to skid or pull to the side when braking, and also reduce braking efficiency. 1. Place the VAZ 2108, VAZ 2109, VAZ 21099 car on the inspection ditch and “push” the rear part of the car several times with a force of about 392-490 N (40-50 kgf) to install the rear suspension in the middle position.

2. Loosen the front bolt securing the brake adjuster to the bracket.

3. Using the wire as a feeler gauge, adjust the bracket so that the gap between the brake pressure regulator drive lever and the lever spring is 2.0-2.1 mm.

4. To do this, move the drive lever by the protrusion. In this position, tighten the bolt. 5. If the brake pressure regulator is correctly adjusted, when braking from a speed of about 40 km/h on a level section of paved road, the front wheels should lock slightly earlier than the rear wheels (this can be determined by an observer outside the vehicle). Otherwise, increase the gap (if the rear wheels lock earlier than the front ones) or decrease it (if the rear wheels lock much later than the front ones). After this, check the brake adjustment again and, if necessary, repeat the adjustment of the brake pressure regulator drive again.

What is a sorcerer for? Is it worth cleaning it up!?

Since ancient times, a brake pressure regulator has been installed on Soviet cars; in colloquial language it is called a sorcerer. This small invention serves to distribute the braking force of the wheels, although it is not for nothing that it was nicknamed the sorcerer because of its unpredictability. If the sorcerer is not working properly, when braking, the car may skid to the side or the brakes may not be effective. Incorrect braking can also be caused by incorrect settings of the sorcerer. The front wheels always start braking, and then the rear ones, but the transition delay time depends on the sorcerer.

To properly configure the sorcerer, load the rear of the car halfway, that is, as much as you usually carry, including passengers, divide in half. We climb into the inspection hole and, using any object two millimeters thick, create a gap between the plate and the sorcerer.

The sorcerer may be faulty due to souring of the rod or internal blockage; it is better not to delay repairs, because faulty brakes are dangerous!!!

When replacing the sorcerer, only the rear brake cylinders need to be bled. To bleed the brakes, unscrew the nipple (not completely) from the inside of the wheel, ask an assistant to press the brake pedal, and bleed air from the system. We press the brake pedal with three long presses and on the fourth press we press the pedal, at this time we loosen the nipple and then tighten it again.

You can remove the sorcerer at your own risk, but at the same time you will have an even distribution of braking force on all four wheels, which will need to be taken into account when braking. The sorcerer can be replaced with a tee (2101-3506091), or bypassed using two brake hoses from a VAZ 2108.

Pinout of the sorcerer tubes:

1. Highway

2. Right wheel

3. Left wheel

4. Highway

When hooking up brake hoses from a VAZ 2108, you just need to connect 1 and 2, 3 and 4. Using a tee, we combine 4 and 1 and hook up 2.3 into the tee.

Personally, I do not recommend removing the sorcerer, and if it is not working properly, then it is better to simply replace it with a new one.

Brake pressure regulator, or how the sorcerer works on VAZ cars

A brake force regulator, or sorcerer in common parlance, is a mechanical device designed to relieve excess pressure in the rear drum brakes.

On VAZ-2109, VAZ-2108, VAZ-2114 and other front-wheel drive models produced in Togliatti, it was installed in the rear left part of the body, under the bottom, in front of the rear suspension beam. The brake pressure regulator on the VAZ-2107 model and other “classics” is located on the right in the direction of travel of the car.

New vehicles equipped with ABS and EBD do not use the sorcerer.

Vacuum booster

This element of the nine's brake system is located between the passenger compartment and the engine compartment. It has a cylindrical shape and is connected via hoses to the carburetor and the brake master cylinder. The main purpose of this unit is to improve vehicle controllability. It is thanks to the vacuum booster that the brake pedal has a very soft stroke, and stopping the car becomes very easy

To truly appreciate the importance of this detail, it is necessary to compare the braking process of the Nine with that of older VAZ models, stopping which took more effort and the braking distance was much longer

Why do you need a brake force regulator?

The function of the regulator is to temporarily reduce the braking force during heavy braking. The fact is that force evenly distributed on the rear and front axles can lead to a skid of the car. If the rear brakes start working a little later and weaker than the front ones, this does not happen.

Based on the above, we can conclude that the sorcerer is an element of the car’s safety system, partly preserving its stability on the road when the brake pedal is pressed in an emergency. On modern models, this function is performed by ABS. That is why there is no need today to use a technically outdated device in production.

Why do you need a handbrake?

But in reality, why do you need a handbrake? If the parking brake is included in the design of the car, then it performs certain functions.

The parking (hand) brake keeps the car stationary on slopes and in parking lots.
In addition to this purpose, the handbrake is used to start and stop on an incline, as well as to enter a controlled skid, but this requires certain skills and experience.
Braking with the handbrake in this case will be carried out with a strong and sharp jerk of the brake lever.

How does a sorcerer work?

The regulator itself consists of a cylinder, valve, spring and rod. The latter is connected to the rear beam, which ensures the operation of the VAZ-2109 sorcerer. Also, brake fluid circuits pass through the rear brake pressure regulator. For their mounting on the device there are 4 threaded entries. » alt=»»> How does the sorcerer regulator work on a VAZ? During emergency braking, the front of the car is pressed to the ground, and the rear is raised. This causes the regulator rod to move, which blocks the flow of fluid to the rear cylinders. A spring located under the valve prevents it from closing completely. Therefore, the rear mechanisms still work, but later and weaker than the front ones.

rav />Neoline CUBEX V50 DVR review – reviews and features

Neoline CUBEX V50 is a fairly expensive DVR that boasts good characteristics and positive user reviews. First of all, you need to pay attention to the type of mounting - the bracket is designed in such a way that it is very easy for the driver to rotate the camera in the vertical and horizontal plane. If you need to quickly remove the camera and capture what is happening on the street, this can be achieved by simply turning the DVR to the side.

A 3-megapixel camera in combination with a powerful Ambarella processor provides good picture quality with a viewing angle of 130 degrees diagonally, that is, not only the roadway, but also the side of the road is captured in the frame. Video recording is cyclic, carried out in small fragments from two to five minutes, even if the power is turned off, the last file will be recorded to the end. In order not to press the buttons on the device body again, you can set the Autostop mode, and the recording will stop as soon as the motor is stopped.

To ensure that all moments are displayed on the video, and the most important recordings are not erased after the memory card is full, there is a G-sensor that can be turned on or off at your discretion. However, a common problem with DVRs on CIS roads is that the shock sensor is too sensitive; it even perceives collisions with bumps or holes as a danger and saves these files in a separate folder, which can only be cleared after removing the memory card.

Setting the brake force regulator

Adjustment of the sorcerer should be done on an overpass or inspection hole. At the same time, the car is unloaded and driven to the work site. To perform the manipulation you will need:

Socket wrench 13 or corresponding socket;
Drill diameter 2 mm.

To adjust the sorcerer, use a wrench to loosen the bolt securing it to the lever bracket. Next, use a screwdriver to move the bracket until the resulting gap allows you to insert a prepared two-millimeter drill into it. After this, the bolt is tightened.

Note: the brake pressure regulator of the VAZ-2110 and previous VAZ models turns sour during operation so that it is not possible to move its bracket. In such a situation, you should pour WD-40 liquid over the rusted area, wait 15-30 minutes, and then use a hammer to move the part to the side using a soft drift.

Replacing brake pipes

Communities VAZ Repair and Modification Blog Brake fluids VAZ 2108 brake pipelines include elements of two types:

rubber reinforced hoses;
steel tubes.

Both of them cannot be repaired. When they fail, they are replaced. If the pipeline leaks while on the move, it can be temporarily insulated with several layers of electrical tape, but only in order to get to the service center and replace the damaged element. Beware of buying hoses from unreliable sellers; there are a lot of crude fakes on the market. Try to purchase spare parts from branded stores and car service centers.

Some VAZ 2108 owners replace corrosion-prone steel tubes with more reliable copper ones. They cut off a copper tube of suitable length, flare the ends and install them in place of the standard ones. The corrosion resistance of such a pipeline increases significantly, but the justification of the costs remains controversial.

Replacing the brake pressure regulator

The replacement of the sorcerer on VAZ-2110 cars and other vehicles equipped with an RTD is carried out on an overpass. You need a 13 mm spanner, a powerful screwdriver and a special 10 mm wrench designed for unscrewing brake pipes. Before starting work, the assembly must be cleaned of dirt and rust, doused with WD-40 or another penetrating compound, and then wait half an hour.

Work begins by unscrewing the bolt securing the bracket to the spring. Afterwards, the brake pipes are dismantled, the position of which is recommended to be pre-marked.

You can also unscrew the tube fittings with a regular wrench. However, using a special tool makes the job easier and reduces the likelihood of “licking” the edges. After the fittings, unscrew the two bolts securing the sorcerer to the body and remove the part. » alt=»»> It is necessary to install the new VAZ-2110 sorcerer in strict reverse order. After installing it and before adjusting the RTD, you should bleed the rear brake circuits. Next, the above-described procedure for setting up the sorcerer is performed.

Examination

The operation of the VAZ-2109, 2110 and other AvtoVAZ models is checked on the move, in closed areas. To do this, accelerate the car to a speed of 40 km/h and sharply press the brake. The rear wheels should lock 1/2 second later than the front wheels.

The wheels are monitored by an assistant located outside the car. If wheel locking occurs noticeably later or does not occur at all, and also if the rear axle is locked simultaneously with the front, the sorcerer adjustment procedure is repeated.

To increase the response time of the rear brakes, the gap between the adjuster and the bracket is increased; to shorten it, it is reduced accordingly.

VAZ 2109: adjusting the brakes yourself is easy and simple

Adjusting the brakes of the VAZ 2109

When the car starts to move away, you often get the feeling that someone is holding it from behind. You need to stop and check the temperature of the rear drum with your hand. If it is heated, therefore, the rear pads jam when braking. Conclusion: it is necessary to adjust the brakes on the VAZ 2109. On a VAZ 2109, adjusting the rear brakes is not difficult. For this reason, repair and inspection work must be carried out to adjust the free play of the brake pedal. Free play adjustment is carried out in the garage. Before starting repairs, you need to check the condition and operation of the rear brake system.

How to determine brake pad wear

The question always arises of when to change the front brake pads; careless drivers begin to change them when they have worn down to metal, thereby creating a metallic squeak when braking.

And a good driver can easily determine the wear of the front brake pads by looking into the hole in the wheel disc, as shown in the photo below; if the pads are very worn, then the metal part of the brake pad will be very close to the brake disc, this is a sign that the brake pads need to be changed.

Examination

VAZ 2109 rear brake adjustment

Raise the rear axle of the car with a jack.
Remove the wheel rims.
Remove the brake drums.
Inspect the brake cylinders for leaks.
Also check their operation, the cylinders should extend to the required distance for braking.
After releasing the pedals, they should not jam. If this flaw is detected, the cylinders must be replaced.
Check the condition of the springs; they should not have any spiral bends. They must also have a flat surface.
Inspect the quality of the pads themselves. There should be no delamination on them, the thickness should be at least 2/3 of the standard.
Also inspect the spacer bar; it should not have any defects, since a damaged bar can interfere with the operation of the pads.
Check the brake drums. There should be no burrs or large grooves on them from the operation of the pads.

Attention. It is necessary to check both sides of the vehicle. After the inspection, replace worn or failed parts if necessary.

VAZ 2109 brake adjustment

To carry out regulation it is necessary:

plate 3 mm thick;
a set of keys;
portable lamp with a protective glass cover, with a protective steel mesh.

The process of adjusting the free play of the brake pedal is carried out to ensure the normal functionality of the entire system. If the stroke is reduced, then the rear pads do not fully return to their position. This causes them and the drums to heat up. Uneven acceleration also occurs at the beginning of movement. With increased free play, pressing the pedal causes the brake pads to incompletely expand.

Pedal adjustment

After the inspection, it is necessary to adjust the brake system:

Raise the hood.
Disconnect the negative terminal from the battery.
Move the front driver's seat from the instrument panel all the way to the rear passenger seats. This must be done for easy access under the steering column.
Hang the prepared lantern in the car to provide sufficient lighting in the area where the adjustment is being made.

Note. Carry out work carefully and consistently.

Press the brake pedal with the palm of your hand. Press without sharp jolts.
With your other free hand, try to install the plate in the space from the pedal bracket to the switch button.

If the plate does not enter or if a larger gap of more than 2 mm is detected, the following actions must be taken:

Hold the pedal with your hand without releasing it.
With your other hand, using a wrench, slightly unscrew the two nuts along the threads. To loosen the brake warning light switch.

Move it carefully to achieve the required space between it and the brake pedal:

Note: The distance should be no more than 5mm.

First tighten one nut, then tighten the second.
Remove your hand from the pedal.
Check the operations performed.
The switch buffer rests against the brake pedal bracket, the adjustment is considered complete.

Handbrake

VAZ 2109 brake regulator

garage room with inspection hole,
regular set of keys.

Engage forward gear.
Place stands under the front wheels for safety.
The rear suspension of the car must be jacked up and supported with reliable supports.

You need to start by checking the lever, which is located inside the car between the two front passenger seats. Raise it two or three clicks. When raised, one click is made, which means the handbrake cable is tightened. This causes the rear drums to become blocked by the brake pads. If more than 8 are produced, then the cable is weakened and the handbrake does not work:

With the handbrake on, go down into the inspection hole.
Loosen the first lock nut on the equalizer.
Tighten the second nut so that the cable is in a taut position.
If necessary, on the contrary, release it.
Check the operation of the lever. It should respond with two or three clicks.

Then tighten the first nut from the hole, tighten with two wrenches to get the effect of tightening two nuts:

After this, turn off the parking system.
Check the rotation of the rear wheel rims.

Make rotational movements with your hands. Their rotation should take place without a jerk, calmly scrolling along the axis of the car. The sound should come out rustling. Consequently, the adjustment of the vehicle's brake system was carried out successfully. The vehicle is ready for continued operation. The brakes can also be adjusted in a car workshop. You can entrust this work to specialists. But the motorist experiences reliability when this work is done independently. A car can be considered technically serviceable when it is inspected and repaired independently. He will never let you down in difficult, dangerous times. In addition, the price of repairs at a service station can be high. When doing the work yourself, you need to carefully watch the video. You also need to study the photos and, if necessary, take them to the repair site. Place it on a rack or in the back seat of the car. If necessary, review them again. Read the instructions for the operation and the location of the necessary structures. Finish the adjustment and check the work done on a free asphalt area.

Brake pressure regulator

Attention. If there are problems with the brake system, then the problem may be hidden in the pressure regulator itself.

VAZ 2109 rear brake pressure regulator

In order to regulate it, you need to know the basic principles of operation of this mechanism, popularly called a sorcerer. As a rule, the sorcerer is attached with two bolts from the bottom of the car. As for one of the bolts, it also simultaneously secures the fork element of the drive lever, which is responsible for pressure. This very element or bracket is the very object with which the movement is carried out and thus the pressure can be adjusted.

Rules for using the parking brake

Before you start driving, you should check the position of the handbrake. When driving with active brakes, the brake pads and discs overheat and wear out faster.

It is not recommended to park the car on the handbrake for more than two weeks, especially on the street. Humid air can lead to corrosion, resulting in a high risk of pads sticking to the wheel rims or drums.

The serviceability of the handbrake needs to be checked regularly (once a month). When the cables stretch, the parking brake needs to be tightened.

You should not leave your car on the handbrake in winter. In severe frosts, due to snow and dirt sticking to the wheels, even when parked for a short time, the brake discs and pads may freeze. It will be impossible to drive a car, and using force can cause serious damage.

In cars with automatic transmission, you should also use the handbrake. This increases the service life of the parking mechanism. In addition, the driver does not have to fear that his car will suddenly roll backwards, hitting a car standing next to him.

If the parking brake is faulty, you should not leave the car even on a slight slope. Failures are also possible with an automatic transmission, and first gear does not always guarantee complete immobilization of the car. Please note that a working handbrake serves as an additional guarantee of the safety of both the driver and passengers, as well as the safety of the vehicle.
