To remove and install, first raise the rear of the vehicle and support it securely on jackstands, then remove the rear wheels and brake drums. If the brake shoes are still in place, operate the ratchet on the adjuster to move the brake shoes apart enough to allow the wheel cylinder to be removed. Disconnect the brake pipe from the wheel cylinder, sealing the end of the brake pipe to prevent dirt entry and loss of brake fluid. Remove the retaining bolts and manoeuvre the wheel cylinder from the vehicle. For installation, reverse the removal procedure while ensuring to tighten the brake pipe fitting and the wheel cylinder retaining bolts to the specified torque, install the brake drum, and adjust the brakes. Bleed the brakes using new brake fluid. For overhauling, if a wheel cylinder is worn or leaking, it may be more economical to install a new or exchange cylinder rather than overhauling the original assembly, so check the price difference before proceeding. Remove the boots, pistons, and spring from the wheel cylinder, then take off the cap and bleeder valve, checking that the valve and port are clear. Clean all parts with methylated spirits or clean brake fluid, and inspect the bore of the wheel cylinder for scoring or pitting; lightly hone cast iron cylinders, while aluminium cylinders that are scored or pitted should be renewed. Lubricate the new seals and pistons with clean brake fluid or a small amount of rubber grease, install the seals to the pistons ensuring the lip faces toward the centre of the wheel cylinder, then install the boots to the pistons, ensuring the end of the boot is correctly located in the groove in the piston. Finally, install the pistons and boots to the wheel cylinder, ensuring the end of the boot correctly locates in the wheel cylinder groove.
