Sectional fragment of the front disc brake caliper
1 – brake caliper; 2 – piston; 3 – rubber sealing ring; 4 – protective dust cuff; 5 – friction segments
The front wheel brakes are disc, caliper, single-piston finger (usually called "with floating pads"). The principle of operation of the brakes is based on the fact that during braking, the fluid pressure acts on the piston located in the caliper, which, shifting, presses the friction segment to the disk. The reaction to this force acts on the bottom of the working cylinder, shifting the caliper in the opposite direction, and thereby pressing the opposite friction segment to the back of the disk. The gap between the disk and the friction segment after releasing the brakes is established automatically due to the springiness of the sealing ring in the cylinder.
Worn friction segments are replaced with similar ones of the same brand and designation and always on both front brakes at the same time (4 pieces). The friction material does not contain asbestos. In order for the brake to work well, the clamp must move smoothly in the guide pins.
The moving surfaces are covered with rubber seals, which must be monitored to ensure that they are not damaged.

The front wheel disks are made of grey cast iron. The disks always have cavities for air cooling from the inside.
