To remove and refit the caliper, raise and safely support the rear of the car, then take off the road wheel. If the caliper is being removed for access to other components, detach the two mounting bolts and carefully support the brake caliper to avoid straining the brake pipe. For dismantling, plug the fluid reservoir outlets, remove the brake pads, and then disconnect the brake pipe from the rear of the caliper, ensuring to plug the end of the pipe to keep dirt out. Lift the caliper from its mountings and refit it in the reverse order, bleeding the brake if the brake line was disconnected. The rear caliper, having two pistons instead of four, shares a similar design and construction with the front caliper, so follow the same dismantling and overhaul procedures, ensuring proper alignment of the piston face cut-outs during reassembly. For brake disc removal, detach the rear brake caliper without disconnecting the brake pipe, ensure the handbrake is fully released, and then separate the brake disc from the axle shaft, refitting it in reverse order while aligning the holes in the brake disc assembly with the stub axle flange.

Dip internal parts in clean brake fluid or apply ATE brake cylinder paste, then use new rubber parts and expansion bolts if the halves were separated. Ensure seals are fully seated, fit the pistons, and install new dust covers with clamp rings.
