Repair and car operation

By pressing a brake pedal pressure of working liquid at the same time affects both the piston, and on a mobile support of the disk brake mechanism. Under the influence of pressure force of liquid the piston presses an internal block to one party of a brake disk. The same force on size affects and a mobile support in which cylinder the piston is established. A support, being displaced on directing fingers, presses to other party of a disk an external brake shoe. The increase in force of influence at a brake pedal leads to pressure growth in a brake hydraulic actuator and to the corresponding growth of the brake moments on wheels which provide delay and a car stop. At an otpuskaniye of a brake pedal pressure in a brake hydraulic actuator decreases to zero. At the expense of elasticity of consolidations the piston and a support depart from a brake disk a little, releasing blocks. In an ottormozhenny condition between surfaces of a friction of blocks and a disk there are small gaps. Such device of a support provides automatic compensation of wear of slips and maintenance of a stable gap between a disk and blocks in use.

On the car back brake mechanisms of drum-type type with active and passive blocks are established. In отторможен in number a condition the top ends of blocks 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 blocks to an internal surface of a friction of a drum. The forward active block in addition nestles on a drum the friction moment, than self-strengthening or servodeystvy blocks is provided. Force of pressing to a drum of a back passive block, on the contrary, decreases because of action of the moment of a friction. When braking the car, moving a backing, the back block is active, and a lobby – passive.

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

The main brake cylinder is equipped with the sensor of level of brake liquid. When falling level of liquid below norm the sensor includes BRAKE signaling device (Brake system). After долива brake liquid and restoration of normal level the signaling device is switched off.
