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.

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.
What is a sorcerer on a VAZ 2114
As just said, every machine has such an important element as a sorcerer. Its correct name sounds like a rear brake pressure regulator. The sorcerer of the VAZ 2114 is responsible for reducing the braking distance and for the absence of skidding during emergency braking, which is extremely important both for the safety of the car and for the safety of its passengers.
This element should be adjusted after any intervention in the car that entailed replacing springs or other suspension elements (which, in turn, could lead to a change in ground clearance). In some cases, it may be necessary not only to make adjustments, but also to completely replace the sorcerer with a VAZ 2114.
You can determine that this part has become unusable by three signs:
- The cuffs have worn out, resulting in a leak of brake fluid.
- In case of sudden braking, the car began to skid strongly.
- The piston of the device has soured.
The first two signs are quite easy to identify, but to identify the last one, you should invite an assistant and conduct a small experiment. One of its participants must press the brake pedal, and the second must monitor the sorcerer's rod.
If it is working properly, the rod should periodically extend (at the moment of pressing) and press on the spring plate, pressing it against the drive lever. If this does not happen, it means the piston is rusty and the sorcerer will have to be replaced.
You should absolutely not ignore the malfunction of the sorcerer, as well as completely dismantle it (as other motorists sometimes advise), since without it the car will lose control when braking and will often skid.
Possible malfunctions of the regulator
In general, there are few malfunctions that can occur in the sorcerer. These include:
- Valve jamming;
- Misalignment of position;
- Brake fluid leaks.
A deregulated sorcerer can be adjusted. You can determine the need for adjustment by the behavior of the car when you press the brake. If the regulator is set incorrectly, the car starts to toss to the side.
If the valve jams or fluid leaks, the mechanism must be replaced. Theoretically, it can be repaired. However, the process of such repairs is complex and expensive, which makes it unprofitable.
How to change the sorcerer
In order to replace a damaged sorcerer, you will first need to purchase a new one. One of the best of this kind is considered to be the brake regulator from. In addition to this, you will also need to purchase a canister of brake fluid, since during the repair process a significant leakage from the system may occur.
To perform the replacement you will need an appropriate set of tools, which includes:
- wrenches “10” (it is highly recommended to use special ones designed for unscrewing brake pipe fittings);
- wrenches “13” (socket and socket);
- a screwdriver with a large blade or a steel spatula;
- feeler gauge (a drill or a 2 mm thick steel plate will also work).
The replacement and adjustment of the VAZ 2114 sorcerer itself should be carried out in the following order:
- Place the vehicle on an overpass or inspection hole.
- Clean the pipe fittings and other threaded connections with a wire brush, then fill them with kerosene or WD-40 and leave it like that for a while.
- Using a screwdriver or a spatula, use a screwdriver or a spatula to pry the clamp-retainer of the regulator drive lever and remove it.
- Disconnect and dismantle the sorcerer lever.
- Unscrew the fittings using a special “10” wrench and immediately plug them with rubber plugs (if you are unable to move the fittings out of place, you should once again flush the threads with “Vedeshka” or kerosene and wait some more time, then try again).
- Unscrew the two sorcerer fastening nuts from the body using a “13” wrench.
- Remove the sorcerer along with its bracket.
- Disconnect the brake pressure regulator from the bracket.
- Attach the new sorcerer to the bracket (there is no need to tighten the bolts all the way).
- Place the bracket with the regulator in its original place, connect the tubes to it and tighten the fittings.
- Connect the lever from the rear beam to the sorcerer and secure it with a clamping bracket (it is important to ensure that the bracket securely grips the lever).
At this point, the installation of the sorcerer can be considered complete, all that remains is to bleed the brake system.
When dismantling the brake pipes when replacing the sorcerer, it is recommended to immediately mark them so as not to confuse them during reassembly.
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. 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.
Adjusting the sorcerer
After the regulator has been replaced, all that remains is to figure out how to adjust the sorcerer on the VAZ 2114.
This should be done as follows:
- Rock the car from side to side several times.
- Use a screwdriver to press the sorcerer pin with such force that the gap between it and the spring is 2 mm (you can check this using a feeler gauge or, more conveniently, the shank of a drill of the appropriate diameter).
- Tighten the first adjusting bolt.
- Check the size of the gap again.
- If it remains unchanged, then tighten the second adjusting bolt.
At this point, the configuration of the sorcerer can also be considered complete.
As you can see, replacing and adjusting the sorcerer will not be difficult for a motorist even with little experience. The only thing worth remembering once again when finishing this article is that you should check the condition of the brake pressure regulator periodically, and if obvious signs of malfunction appear, replace it immediately.
DEVICE OF BRAKE MECHANISMS
Many people wonder what is the difference between the brake mechanisms of the front wheels and the rear ones. The fact is that when braking, they are subject to different loads, and they do not operate synchronously. But this is not the main reason for the differences.
The front mechanisms consist of:
- Brake disc of classic design;
- Direction pads;
- Calipers;
- Directly the pads themselves;
- Cylinder;
- Piston;
- Seal rings;
- Protection casing;
- Direction finger;
- And its cover, which performs a protective function.
The design of the front brakes is a little simpler than the rear, however, this does not mean that they play a lesser role in braking. After all, these are the mechanisms that work first.
- Nuts that secure the hub;
- Actually, the hub itself;
- Tension springs (lower and upper);
- Brake pads;
- Directional springs;
- Wheel cylinder;
- Expansion bar;
- Handbrake lever finger;
- Handbrake lever;
- Mechanism casing.
As we can see, this difference in design is caused by the presence of parking brake elements in the rear mechanism. Therefore, the part itself looks much more massive. The operating principle of the hydraulic part is the same as in the front. The only difference between the rear brakes is this.
A simple diagram of the VAZ 2114 brake system allows you to easily carry out any repairs yourself. Spare parts for domestic cars are inexpensive and quite common, which greatly simplifies operation and repair work. This is why VAZ cars are in such demand and provide good competition to foreign cars.

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.
