If replacement is indicated, usually 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, making the job easier. Always replace calipers in pairs. To remove, first loosen the wheel lug nuts, raise the vehicle, and securely place it on jackstands before removing the wheels. Disconnect the brake hose from the caliper by removing the banjo fitting bolt and caliper mounting bolts, discarding the sealing washers and plugging the brake hose to prevent contamination and fluid loss. If the caliper is removed for access to another component, hang it securely with wire, ensuring it does not hang by the brake hose. For rear calipers on 2012 and earlier models, disconnect the parking brake cable. For 2013 and later models, activate the Electronic Parking Brake service mode, disconnect the electrical connector to the EPB actuator, and remove the ERB actuator if necessary. To install, reverse the removal procedure, tightening the mounting bolts and banjo fitting bolt with new sealing washers. Bleed the brake system and check for leaks. For 2012 and earlier models, adjust the parking brake if needed, and for 2013 and later models, deactivate the EPB service mode after replacing the rear caliper. Finally, test the brakes carefully before returning the vehicle to normal service.
