6.2.3. Disk brake mechanisms of forward wheels

The support of the brake mechanism fastens on a rotary fist two bolts. The liquid pressure created by pressing of a pedal of a brake will be transformed to brake force. This force affects equally the piston and a support. As a result the piston starts outside, and the support moves inside, clamping a brake disk. When tightening friction force between frictional overlays of brake shoes and brake disks which promotes a car stop is created.

ATTENTION
Surely replace all blocks even if only one is worn-out. If brake shoes are established repeatedly, before removal they need to be marked.

By pressing a brake pedal brake fluid presses on the piston, moving it from the cylinder. The piston epiploon at action of considerable pressure upon the piston moves together with the cylinder. However, as a part of an epiploon of the piston is recorded in a flute which form corresponds to a sealant form, the top part of an epiploon is deformed in the direction of the movement of the piston.
At a brake pedal otpuskaniye pressure of brake fluid decreases, and the elastic force created by deformation of an epiploon of the piston returns the piston in a starting position.
In process of wear of brake slips and increase in a gap between a brake disk and slips the piston moves even more, thereby keeping a gap former. The epiploon form can change further, but as an internal part of an epiploon is fixed in a cylinder flute, the size of deformation remains former. The piston moves further for overlapping of a gap. As the piston comes back to a starting position, the gap between a brake disk and brake slips is supported at the required level.
