Fig. 6.1. Scheme of the working brake system: 1 – disk brakes; 2 – signaling device; 3 – main cylinder; 4 – vacuum amplifier; 5 – drum brakes; 6 – pressure regulator


Technically serviceable brake system (fig. 6.1) provides uniform, without drift a car zatormazhivaniye. When braking from the speed of 50 km/h on the horizontal section of the road with a dry concrete covering delay has to make 8 m / с2 at effort to a brake pedal of 300 N (30 kgfs). The working course of a pedal at the same time should not exceed 100 mm.
The parking brake has to hold the car on a bias not less than 25%, at the same time the lever of the parking brake has to move no more than to six clicks. Specialized stands are used to control of efficiency of operation of the brake system.
The nominal sizes, admissions and landings of the main interfaced details of the brake system are specified in tab. 6.1.
