Disc Brake System: Description and Operation

The disc brake caliper bolts to the front wheel knuckle.
A separate front disc brake rotor attaches to the wheel hub.

The disc brake caliper:
- is a pin slider, dual piston type.
- has two caliper pistons.

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 cylinder 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

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.
