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 directly on the brake piston and also on the walls of the brake cylinder. The brake piston presses the inboard brake pad against the brake disc while at the same time the hydraulic body slides sideways and presses the outboard brake pad also against the brake disc. When the hydraulic pressure is released, the piston sealing ring (3) retracts the brake piston in each brake cylinder to the rest (brake off) position.
