CAUTION: The brake caliper is aligned / centralized to the brake disc when the vehicle is built. The vehicle may

have shims fitted between the brake caliper anchor plate and the wheel knuckle. Care must be taken not to disturb this
alignment. When removing caliper; remove only the bolts that secure the brake caliper to the brake caliper anchor plate.
DO NOT loosen any other caliper bolts. This alignment / centralization MUST be checked / set when the wheel knuckle is
replaced. Failure to follow this instruction may result in damage to the vehicle.

The rear disc brake system consists of the following components:



Brake pads



Four piston, apposed brake calipers



Ventilated brake discs



Brake caliper anchor plates



Steel braided brake hoses



Tamper proof brake bleeding screw shields

The brake caliper has two retaining bolts that attach the brake caliper to the brake caliper anchor plate. The
brake caliper anchor plate is attached to the wheel knuckle with two bolts. The hydraulic system provides
separate circuits for each pair of diagonally opposed wheels (i.e. left front, right rear and right front, left
rear).

The brake disc is manufactured from cast iron and is of the grooved vented type. It is retained on the hub by
two retaining clips and the wheel studs.
