Brake system

The general information

All models of cars considered in the present Management are equipped by hydraulic brake system with vacuum strengthening. On forward wheels disk brake mechanisms, on back - both disk, and drum-type are always established.
All brake mechanisms are equipped by self-regulators. Thus indemnification of deterioration brake колодок disk mechanisms is carried out automatically whereas, on drum-type mechanisms the special adjusting devices which activation occurs at raising of a lay brake are established.

The main brake cylinder (ГТЦ) is established on assemblage of the servo-driver of the vacuum amplifier of the brakes, fixed on a back partition of an impellent compartment. From above on the cylinder the big tank of a hydraulic liquid equipped with a plastic cover is located.

ГТЦ has the dual design providing functioning of two independent hydraulic contours (forward and back). Pressure of a liquid in each of contours is forced by the individual piston in separate chambers of the main cylinder. As primary piston GTTS directly (through a metal rod) is connected to a pedal of a foot brake moving of last inevitably conducts to increase of hydraulic pressure in brake lines. Instant increase of pressure in lines leads to moving of pistons to supports / wheel cylinders of brake mechanisms, and the size of effort developed by last increases proportionally to an increment of the area of their pistons concerning the area of pistons GTTS.

Wheel cylinders of drum-type brake mechanisms are equipped by two pistons which are pushed out in opposite directions and brake boots providing a clip to a working surface of a drum. In disk mechanisms cylinders are built in assemblages of supports and provide possibility сжимания a brake disk between two frictional колодками.

Brake kolodki/boots, and also pistons GTTS are equipped by returnable springs that guarantees system transition in an initial condition at отпускании pedals of a foot brake.

Tightness of planting of pistons in cylinders is provided at the expense of use of rubber sealing cuffs, for protection of cylinders against a dirt and a moisture are provided special пыльники.

The main brake cylinder

In the main brake cylinders of two-planimetric brake systems two pistons established directly one after another are used. The primary piston by means of a metal rod is directly connected to a brake pedal. The drive of the secondary piston is carried out by hydraulic image at the expense of the prisoner between pistons of volume of a liquid. At formation of leaks ahead of the secondary piston, last is displaced forward against the stop in a face wall of the cylinder and the liquid being between pistons gets only to a b
