The hydraulic brake system consists of the main brake cylinder, the amplifier of a brake and disk brakes of forward 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 liquid leak braking of the car is carried out by other contour. Liquid pressure in both contours is created by the doubled main brake cylinder operating from a brake pedal.
The description of work of systems of anti-blocking of brakes of ABS, the amplifier of emergency brake application of BAS and the electronic program of stabilization of stability (antistrange system) is provided to the Operation manual.
The tank with brake fluid is under the main brake cylinder, it supplies with liquid all hydraulic system of braking.
The amplifier of a brake accumulates a part of the vacuum created in the soaked-up engine pipeline. 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 effect of vacuum.
The parking brake with the 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 brakes which are built in disk brakes are in addition established. Drum brakes are put in action only from a pedal of the parking brake.
In the course of rotation of a wheel moisture under the influence of centrifugal force is dumped from brake disks, but there is a silicone film, rubber attrition products, lubricant and other pollution reducing efficiency of brakes.
