The hydraulic brake system consists of the main brake cylinder, the amplifier of a brake and disk brakes of lobbies and back wheels. The brake system has two contours. One contour influences forward brakes, another - on back. At refusal of one of contours, for example, owing to leakage of liquid braking of the car is carried out by other contour. Pressure of liquid in both contours is created by the doubled main brake cylinder operating from a pedal of a brake.
The description of work of systems of anti-blocking of brakes of ABS, the amplifier of emergency braking of BAS and the electronic program of stabilization of stability (Protivozanosny system) is provided in the Operation manual.
The tank with brake liquid is under the main brake cylinder, it supplies with liquid all hydrosystem of braking.
The amplifier of a brake accumulates a part of the vacuum created in the soaked-up pipeline of the engine. As the diesel engine has no necessary vacuum on absorption, cars with the diesel engine have the special vacuum pump. By means of the corresponding valve if necessary the effort to pedals of a brake increases thanks to vacuum action.
The parking brake with a pedal drive influences through cables brakes of back wheels. As as the parking brake the disk brake does not work, on back wheels the drum-type brakes which have been built in disk brakes are in addition established. Drum-type brakes are put in action only from a pedal of the parking brake.
In the course of wheel rotation moisture under the influence of centrifugal force is dumped from brake disks, but there is a silicone film, products of an istiraniye of rubber, greasing and the other pollution reducing efficiency of brakes.
