Cover the open cylinder with a clean rag. Stuff old rags around and under the cylinder, to catch any brake fluid that overflows.
Loosen the lug nuts on all the rear wheel lugs. Raise the rear of the car, and support it with a jack stand on each side. Remove the lug nuts and both rear wheels.
Place a drip pan or newspapers below the brake assembly. Spray the entire front brake assembly with a liberal amount of brake cleaner, and allow the parts to dry.
Use a socket to remove the upper sliding pin bolt from the caliper.
Rotate the caliper downward and out of the torque member. Use a piece of wire to support the caliber, so the brake line is not stretched.
