A: If replacement is indicated, explore all options before beginning this procedure. New and factory rebuilt calipers are available on an exchange basis, which makes this job quite easy. Always replace the calipers in pairs - never replace just one of them. Loosen the front wheel lug nuts, raise the vehicle and support it securely on jackstands. Remove the front wheels. Unscrew the banjo bolt from the caliper and detach the hose. Discard the sealing washers on each side of the fitting and use new ones during installation. Plug the hose to prevent fluid loss and contamination. Clean the caliper assembly with brake system cleaner. Install the Brake Pads and caliper. Tighten the caliper guide pin bolts. Connect the brake hose to the caliper using new sealing washers. Tighten the banjo bolt. Firmly depress the brake pedal a few times to bring the pads into contact with the disc. Check the fluid level in the master cylinder reservoir and add more if necessary. Bleed the brakes. Install the wheels and lug nuts. Lower the vehicle and tighten the lug nuts. Carefully check for fluid leaks and test the operation of the brakes before resuming normal operation.
