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

The working brake system provides regulation of speed of the car and its stop with necessary efficiency.

The spare system provides a car stop with necessary efficiency at failure of the working brake system.

The parking system serves for keeping of the car in motionless, concerning the road, a state. This system can be used 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. 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. On forward wheels not ventilated brake disks, and on cars with engines over 79 kW (107 h.p.) — the ventilated brake disks are established. On back wheels the self-established drum brakes, and on cars with engines over 79 kW (107 h.p.) — disk are applied.

The tank of the main brake cylinder is in a motor compartment, supplying the brake system and coupling with brake fluid. The vacuum amplifier of brakes reduces effort on a brake pedal, facilitating thereby driving.

The brake mechanism of a forward wheel disk with a mobile bracket. He well fits into a wheel, has a small amount of details, including consolidations, and small weight. As in the course of a thermolysis only one cylinder is involved, brake fluid heats up less.

The parking brake influences back wheels via the hummock drive. Blocks of forward and back brakes are regulated automatically.

Some models of cars are equipped with ABS including the hydraulic modulator, an electronic control unit, the relay and sensors of speed of rotation of wheels. The system prevents blocking of wheels at sharp braking. Control lamps of the parking brake, low level of brake fluid and the ABS system warn about a condition of the brake system.

PREVENTION During the work of brake shoes brake dust which contains asbestos, unhealthy is formed. Therefore when cleaning brake shoes do not use compressed air and try not to breathe air from a working zone.

PREVENTION At movement along the damp road due to centrifugal force water is dumped from brake disks, however on them there is a thin film from fats, silicones, the remains of rubber, lubricant and dirt reducing efficiency of braking. Therefore during a car stop after the movement in the rain dry brakes pressing a brake pedal.

PREVENTION New brake shoes have to pass the period "extra earnings". On the first 200 km of a run avoid sharp braking. Corroded brake disks cause when braking vibration effect, not disappearing and at long braking. Such brake disks need to be replaced.
