If replacement is indicated, usually due to fluid leakage, it is recommended that the calipers be replaced instead of overhauled, as new and factory rebuilt units are available on an exchange basis, making this job quite easy. Always replace the calipers in pairs and never just one. To remove, first loosen the front wheel lug nuts, raise the front of the vehicle, and securely place it on jackstands before removing the wheel. If the caliper is being removed to gain access to another component, do not disconnect the hose. Next, remove the bolt and disconnect the brake hose from the caliper, plugging the hose to keep contaminants out and to minimize brake fluid loss. Discard the sealing washers and use new ones during installation. Then, remove the caliper mounting bolts while holding the slide pin with an open-end wrench and using a socket or boxed-end wrench on the bolt. With the caliper mounting bolts removed and the line disconnected, take out the caliper. For installation, reverse the removal procedure, ensuring to replace the sealing washers at the brake hose-to-caliper connection, and tighten the caliper mounting bolts along with the brake hose banjo fitting bolt. Finally, bleed the brake circuit, checking for leaks from the hose connections, and test the brakes carefully before returning the vehicle to normal service.
