Disc Brake System: Description and Operation


Front Disc Brake Components:





The front disc brake hub and rotor is an integrally cast assembly.

The disc brake caliper:
- bolts to the front disc brake caliper anchor plate, which bolts to the front wheel spindle.
- is a pin slider, dual piston type.

The caliper housing has a fluid inlet at the center of the bore. A square section seal fitted into an annular groove in the caliper bore seals against hydraulic pressure, while rubber boots seal the caliper pistons and caliper bore from contamination.

The front disc brake rotor shield:
- bolts to the front wheel spindle.
- protects the bearings and inboard surface of the front disc brake hub and rotor.

The pads are:
- contained within the front disc brake caliper anchor plate.
- held to the front disc brake caliper anchor plate abutments by disc brake anti-rattle clips.
