Brake force regulator: overview, device, adjustment, prices

This device, which is popularly called the "sorcerer", is one of the important elements in the brake system of any car. The main function of the brake force regulator is to prevent the car from drifting. In more modern domestic and foreign models of cars, the traditional mechanical regulator is no longer there. His place was taken by electronic assistants. In particular, the function of the "sorcerer" performs the EBD system. But in the basic configurations, manufacturers save on everything, so sometimes mechanical regulators are found even in new foreign cars. Let's look at what a given element represents, what it is for in a car, how to tune it.

Functions and Purpose

The brake force regulator is used to automatically change the fluid pressure in the cylinders of the rear brakes of the car. In this case, the adjustment is carried out as the loads acting on the machine at a decrease in speed.Such regulators are used in systems with pneumatic or hydraulic drive. It is necessary to change the pressure of the cylinders in order to prevent complete locking of the rear wheels. If they are blocked, the car will go, the driver may lose control.

In some models of cars, in order to maintain controllability and stability, they additionally use similar mechanisms-regulators on the brake drives of the front wheels.

In addition, the brake force regulator is used to improve the efficiency of stopping an empty car. When the machine is not loaded, its grip will be different from the clutch of the loaded car. Therefore, it is very important to necessarily change the braking force on different axes. In cars, static devices are used as regulators. In trucks, automatic solutions are installed.

In the cars created for sport, apply another kind of "sorcerers". This is a screw regulator. What it is? It is located in the cabin, and with it you can adjust the balance of the brake system directly in the race.The settings depend on the weather, the condition of the track, and the condition of the rubber.

How is the mechanism?

It should be noted that the brake force regulator is not installed on machines with ABS, although the “warlock” is the ancestor of this system. It also protects the wheels from locking during braking.

In passenger cars, the “witch” has a fairly simple device. It consists of three elements - it is the housing, the pistons, and also the valves.

The case of the device inside is divided into two cavities. The first cavity of the regulator is connected to the master cylinder (GTZ). The second is connected to the rear brakes. When emergency braking is necessary, the front of the machine will tilt. With the help of pistons and valves due to this tilt access of the working fluid to the brake cylinder will be blocked.

Thus, the VAZ brake force regulator automatically controls and distributes the forces on the wheels of the rear axle. The machine does not go into a skid in case of an emergency pedal.

Where is the regulator

"Koldun" can be found in a passenger car mainly in the rear.It can be both on the left and the right on the bottom.

The regulator is in conjunction with the rear axle or beam by means of thrust and a special torsion lever. It is this lever that has an effect on the piston inside the regulator. The incoming part of the brake force regulator is connected to the GTZ, and the output part is connected to the working brake cylinders of the rear mechanisms.

Operating principle

When the driver makes a sharp push on the pedal, the car will “bite” the front end of the body. As a result, the back end will rise slightly. At the moment, and launched into the "sorcerer."

If the rear pair of wheels will brake together with the front ones, then in this case the probability of the vehicle skidding significantly increases. If the wheels on the rear axle will stop later than the front ones, then in this case the risks that the car will go into a skid are minimal.

When the braking process is carried out, the distance between the bottom and the rear axle of the car increases. Due to this, the piston of the brake force regulator VAZ-2110 is released. As a result, the line with the liquid inside overlaps. The wheels will not be locked, but will continue to rotate.

How to check the regulator?

"Sorcerer" this device is called for a reason. Although many beginners really do not know how it works. Let's see how to check the operation of the regulator to see if it is working properly.

For the test, you will need at least two people - one will drive the car, and the second will monitor the car. The driver during the test will have to accelerate an empty car on a flat stretch to a speed of about 60 kilometers per hour. Then you must perform a sharp braking. Further, at the moment, the observer should control how the rear wheels work. It is important to notice whether they are locked or rotate when you press the brake pedal.

If the rear wheels lock immediately or they continue to rotate and do not respond to the pedal being pressed, the brake force regulator 2110 is faulty.

What happens if you drive without a regulator?

If the check showed that the “sorcerer” is not working, then the owner of the car has two options. The first and most correct is the purchase and installation of a new regulator. The second option is to remove the “sorcerer” from the system. Let's see what threatens the operation of the car without this device. Some owners even deliberately remove the regulator to reduce the braking distance.

However, experts do not recommend removing the mechanism - this is the wrong way. Without a regulator, both the front and rear brakes will operate simultaneously. There is a growing risk of a possible accident - a driver moving behind may not be able to react correctly to the braking process.

The presence of a good brake force regulator at the 2114th VAZ is very important. Removing it from the system is prohibited - this is indicated in the SDA. If the mechanism does not work correctly, you can try to adjust it.

How to adjust the distributor VAZ?

In order to distribute the workload to the front and rear brake drives as correctly as possible, adjustments should be made periodically. Its principle is as follows. There is a gap between the end of the piston and the plate. It can be from two to three millimeters. However, the difficulty is that the size of the gap is inaccurate. It is determined by experience. To perform more precise adjustment of the brake force regulator, move the regulator along its bracket.

The parameters of the gap should be selected depending on how the rear wheels behave in each case.If it is not observed when braking the wheels of the rear axle, then the clearance can be reduced. If the rear brakes are applied earlier than the front brakes, then the clearance should be increased.

Service

This part is not subject to repair. But in order for it to work normally, it needs to be serviced. This is usually done before making adjustments. The node is installed in an unfavorable place - during operation, water, snow, dirt, reagents from the road fall on it. All this worsens the work. Gradually, water and snow are causes of corrosion.

General maintenance measures are to clean the “sorcerer” from rust, remove the old rubber boot and install a new one, replace the lubricant, clean all elements of the regulator from contamination. Pre-removal of old grease from the anther.

“Sorcerer” adjustment on “Logan”

Finding the brake regulator on Logan is not a problem. It is located on the bottom between the front and rear axles. Many claim that the right to set up the work of the distributor on this car is only for professionals, but this is not at all the case. Primary adjustment is performed by the manufacturer - a special installation is used, and the nut is pulled with a strictly defined moment.Only fixing the free thread on the nut is allowed.

For self-adjustment, you need to clean the “sorcerer” and replace the grease in it. Then make half a turn with an adjusting nut. Then you can go to the test. If the rear pair of wheels does not brake, then tighten the nut again.

If there is no ABS on the tested car, then even if you stretch the nut up to the stop, you may not achieve a result. Sometimes it may help to replace the sorcerer, but this does not always save the situation. The fact is that in 9 out of 10 “Logans” without ABS, the regulator does not work in principle. The reasons are weak spring. And the owner has two options again - he can change the springs for more rigid ones or install a rubber gasket to increase the pressure on the “sorcerer” mechanism.

Replacing the regulator on the tee

Motorists sometimes perform the replacement of the standard "sorcerer" on the tee. Among the reasons are the initial malfunction of the node, souring and failure, various other problems. Tee allows you to simultaneously block and evenly distribute the braking force between all wheels.

Among the minuses can be distinguished dangerous braking (especially in winter in ice), the risk of skidding.Among the advantages - a sharp and responsive brake pedal.

Price

Car manufacturers do not recommend excluding the “sorcerer” from the brake system of the car. Moreover, the price of the brake force regulator for VAZ models ranges from one and a half thousand rubles. This is a low cost, considering that security depends on the “sorcerer”.

Conclusion

So, we found out what the item is. As you can see, its presence is very important in the brake system of any car. Thanks to the "sorcerer" machine is not included in the skid during emergency braking. Therefore, it is definitely not worthwhile to get rid of such an element.
