Front brake caliper

Front brake caliper


Each brake caliper consists of a hydraulic body with brake piston and two brake pads in a carrier. The front hydraulic body slides on two guide pins mounted on the carrier. The guide pins are manufactured in stainless steel and should not be lubricated.

There is one version of the hydraulic body, with a piston with two recesses to give a smaller area of contact with the brake pad and improved piston cooling. This design transfers only a small amount of heat to the brake fluid. The brakes are therefore able to withstand high thermal loads. However, it is important that the brake piston is fitted correctly after being dismantled so that correct cooling is attained. See .

When the brakes are applied, the hydraulic pressure acts partly on the brake piston directly and partly on the walls of the brake cylinder. The brake piston presses the inner brake pad against the brake disc. At the same time, the hydraulic body slides to the side and presses the outer brake pad against the brake disc as well. When the hydraulic pressure ceases, the brake piston in each cylinder is returned to its rest position by the piston ring.
