Brake caliper, front wheel
|
The brake caliper for each front wheel consists of a hydraulic body (2) with a brake piston (3), two brake pads (4) and a carrier (1). The hydraulic body slides on two guide pins mounted in this carrier. One version of the hydraulic body has a single brake piston and a characteristic of this design is that only a small amount of heat is transferred to the brake fluid. The brakes are therefore able to withstand a high thermal load.
When the brakes are applied, the hydraulic pressure acts partly directly on the brake piston and partly on the walls of the brake cylinder. The brake piston presses the inner brake pad against the disc. At the same time, the hydraulic body slides laterally so that the outer brake pad is also pressed against the brake disc. When the hydraulic pressure ceases, the brake piston is returned to its rest position by the piston sealing ring (5).
