Brake Caliper: Description and Operation

Disc Brake Caliper Assembly:

This caliper has a single bore and is mounted to the support bracket with two mounting bolts. Hydraulic pressure, created by applying force to the brake pedal, is converted by the caliper into friction. The hydraulic pressure is applied equally against the piston and the bottom of the caliper bore moving the piston outward, resulting in a clamping action on the brake rotor.
