Loosen the wheel lug nuts, raise the front or rear of the vehicle and support it securely on jackstands. Release the parking brake lever if you're working on the rear brakes and remove the disc brake pads. Place a container under the caliper and have some rags handy to catch any spilled brake fluid. On non-Brembo models, clean the caliper lock pin and guide pin, then lubricate the pin with high-temperature grease. On Brembo models, clean the locking clips, pad pins and cross spring. Install the caliper assembly and, if necessary, reconnect the 
Brake Line to the caliper using new sealing washers and tighten the banjo bolt and the caliper bolts. Install the wheel and lug nuts, lower the vehicle and tighten the lug nuts. Finally, bleed the brake system.
