To begin the brake removal process, start by removing the cap from the brake fluid reservoir and draining about two-thirds of the fluid. Then, loosen the wheel lug nuts, raise the vehicle, and secure it on jackstands, and remove the wheels.

To begin the brake removal process, start by removing the cap from the brake fluid reservoir and draining about two-thirds of the fluid. Then, loosen the wheel lug nuts, raise the vehicle and secure it on jackstands, and remove the wheels. Work on one brake assembly at a time, positioning a drain pan underneath and cleaning the caliper and surrounding area with brake system cleaner. Use a C-clamp to push the piston back into its bore, being careful not to overflow the fluid in the master cylinder. On older models, remove the caliper mounting bolts and lift the caliper off the disc, removing the outer and inner pads. Remove the mounting bolt seals and rubber bushings from inside the caliper ears, clean and inspect the caliper and mounting bolts, and replace them if necessary. Install new rubber bushings and seals in the caliper, filling the space between the bushings with silicone grease. Apply anti-squeal compound to the backing plates of the new brake pads and position the inner and outer pads in the caliper. Hold the caliper in position over the disc, insert and tighten the mounting bolts. For installation, repeat the process on the opposite wheel, install the wheels, and lower the vehicle. Add brake fluid to the reservoir and pump the brakes to seat the pads against the disc. Check the fluid level and test the brakes before driving. On newer models, pivot the caliper up to expose the brake pads and follow the same steps. Finally, tighten the mounting bolts and wheel lug nuts to the proper torque specifications, depress the brake pedal to bring the pads into contact with the disc, and check the brake fluid level and operation of the brakes before normal use.
