Always replace the calipers in pairs - never replace just one of them. To remove the calipers, first loosen the wheel lug nuts, raise the vehicle, and securely support it on jackstands. Remove the wheels. Next, remove the brake hose banjo bolt and disconnect the hose from the caliper. Plug the hose to keep contaminants out of the brake system and prevent losing any more brake fluid than necessary. If you're just removing the caliper for access to other components, do not detach the hose. Then, remove the caliper mounting bolts and the caliper itself. If necessary, remove the caliper bracket from the steering knuckle or rear knuckle. To install the caliper, reverse the removal procedure. Tighten the caliper mounting bolts and bracket bolts. Install new sealing washers on either side of the brake hose banjo fitting, then tighten the banjo bolt. Bleed the brake system. Finally, install the wheels and lug nuts. Lower the vehicle and tighten the lug nuts.
