According to the destination and to the carried-out functions the brake system of the car is subdivided on working, spare, parking and emergency.

The working brake system provides regulation of speed of the car and its stop with necessary efficiency. Spare serves for a car stop with necessary efficiency at failure of the working brake system.

Parking serves for deduction of the car not movably concerning the road. Generally use it for deduction of the standing car, but it can be applied also as the working brake system, emergency at failure.

On the car the working brake system with the hydraulic drive and diagonal division of contours is used that considerably increases safety of driving of the car. At refusal of one of contours as the spare brake system the second contour providing a car stop with sufficient efficiency is used.

The brake system consists of the main brake cylinder, the vacuum amplifier of brakes, disk brakes on forward wheels and drum or disk brakes on back wheels.

The vacuum amplifier of brakes reduces effort a brake pedal, facilitating thereby driving.

The regulator of pressure of back brakes is located in a hydraulic actuator on each back brake. On the majority of models regulators of pressure are located separately, but on some models with back brake drums regulators of pressure are combined with back working cylinders.

On cars with diesel engines the separate vacuum pump which is installed on the end of a head of the block of cylinders is used to creation of the vacuum ensuring functioning of the vacuum amplifier of brakes and put in action directly from the camshaft.

At movement along the damp road it is recommended to press a brake pedal from time to time to remove harmful inclusions from brake disks. Due to centrifugal force water at the movement is dumped from brake disks, however on them there is a thin film from fats, silicones, the remains of rubber, lubricant and dirt which reduce efficiency of braking.

After installation of new brake shoes they have to be earned extra. On the first 200–300 km of a run it is not recommended without need to make the maximum braking.

Corroded brake disks cause vibration effect which does not disappear at long braking when braking. In this case brake disks are subject to replacement.
