The main brake cylinder is intended for a two-planimetric brake drive with the diagonal scheme of division of contours. The two-section brake cylinder is in addition equipped by the gauge of level of a brake liquid in a tank and regulators of brake forces (proportional valves).

By pressing a brake pedal pressure of a working liquid simultaneously operates both on the piston, and on a mobile support of the disk brake mechanism. Under the influence of a pressure force of a liquid the piston presses internal колодку to one party of a brake disk. The same force on size operates and on a mobile support in which cylinder the piston is established. A support, being displaced on directing fingers, presses to other party of a disk external brake колодку. The increase in force of influence at a brake pedal leads to pressure growth in a brake hydrodrive and to corresponding growth of the brake moments on wheels which provide delay and a car stop. At release a brake pedal pressure in a brake hydrodrive decreases to zero. At the expense of elasticity of consolidations the piston and a support depart from a brake disk a little, releasing Pads. In отторможенном a condition between friction surfaces колодок and a disk there are small backlashes. Such device of a support provides automatic indemnification of deterioration of overlays and maintenance of a stable backlash between a disk and колодками while in service.

On the car back brake mechanisms of drum-type type with active and passive колодками are established. In отторможен ном a condition the top ends колодок are pressed by springs to pistons, and the bottom ends – to an emphasis located on a basic brake disk. By pressing a brake pedal pistons press Pads to an internal surface of a friction of a drum. The lobby active колодка in addition nestles on a drum the friction moment, than self-strengthening or серводействие Pads is provided. Force of pressing to a drum back passive Pads, on the contrary, decreases because of action of the moment of a friction. At braking of the car, moving a backing, back колодка the lobby – passive is active, and.

Regulators are intended for restriction of rate of increase of pressure in a brake hydrodrive of back wheels after achievement in the main brake cylinder of certain size of pressure. It limits the brake moments of back wheels and probability of their blocking at intensive enough braking. Similar regulators of brake forces apply usually on the cars equipped with disk forward and drum-type back brake mechanisms.

The main brake cylinder is equipped by the gauge of level of a brake liquid. At falling of level of a liquid below norm the gauge includes signalling device BRAKE (Brake system). After долива a brake liquid and restoration of normal level the signalling device is switched off.
