Disc Brake
The disc brake assembly consists of a caliper, piston, rotor, pad assembly and support bracket. On 2002 models, the caliper assembly has a single bore. On 2003-04 models, the caliper assembly has a front dual bore and rear single bore. The caliper assembly is mounted to the support bracket with 2 mounting bolts. The support bracket allows the caliper to move laterally against the rotor. The caliper is a one-piece casting with the inboard side containing the piston bore. A square cut rubber seal is located in a groove in the piston bore which provides the hydraulic seal between the piston and the cylinder wall.
Hydraulic pressure, created by applying the brake pedal, is converted by the caliper to a stopping force. This force creates a clamping action of the piston pressing towards the rotors (outward) and the caliper slides inward toward the vehicle. This clamping action forces the linings against the rotor, creating friction to stop vehicle.
