Front Disc Brakes
Front disc brakes are standard on all models. A dual piston front caliper assembly is used on all models. On 2WD models, the disc brake caliper bolts to the front wheel spindles. The brake disc and hub is an integrally cast assembly. See Fig 1. On 4WD models, the disc brake caliper bolts to the front wheel knuckle. A separate brake disc attaches to the wheel hub. See Fig 2.
On all models, the disc brake caliper is a pin slider, dual piston type and 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 brake disc shield bolts to the front wheel spindle and protects the bearings and inboard surface of the brake disc. The pads are contained within the front disc brake caliper anchor plate and are held to the front disc brake caliper anchor plate abutments by disc brake anti-rattle clips.
