If replacement is indicated, typically due to fluid leakage, it is recommended that the calipers be replaced rather than overhauled, as new and factory rebuilt units are available on an exchange basis, simplifying the process. Always replace calipers in pairs. To begin, loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands while blocking the wheels at the opposite end before removing the wheels. For rear calipers, disconnect the parking brake cable from the caliper by detaching it from the lever and then removing it from the bracket. Use a C-clamp to depress the caliper piston just enough to allow the pad to clear the rotor, ensuring not to damage the caliper, especially since it contains an integral parking brake mechanism. Inspect the parking brake side of the caliper for any signs of brake fluid seepage, as any leakage indicates the need for replacement. Disconnect the
Brake Line from the caliper and plug it to prevent contamination and minimize brake fluid loss, unless the caliper is being removed solely for access to other components. Remove the caliper mounting bolts and detach the caliper from its mounting bracket. For installation, reverse the removal procedure, replacing the copper sealing washers on either side of the brake line fitting with new ones, and tighten the caliper mounting bolts and brake line banjo fitting bolt to the specified torque. Finally, bleed the brake system, install the wheels and lug nuts, lower the vehicle, and ensure the wheel lug nuts are tightened to the specified torque, checking the operation of the brakes thoroughly before returning the vehicle to normal service.
