Steps
Lift the rear and remove the wheel
Loosen wheel nuts on the ground, raise the rear at approved points, and support it with jack stands. Remove the wheel and inspect brake wear.
Remove caliper and rotor
Hold the slide pin while removing caliper fasteners, then support the caliper so its hose is not loaded. Remove pads, bracket, and rotor.
Retract the rear piston
Use a rear caliper rewind tool to rotate and retract the piston while aligning its face as required. Do not press it straight in, which may damage the parking-brake mechanism.
Install the new brakes
Seat the replacement rotor, clean the pad slides, and install the pads. Align and refit the caliper, tightening all fasteners to the vehicle specification.
Refit the wheel and verify operation
Tighten wheel nuts in a star pattern to specification. Pump the pedal until firm, check parking-brake release, and do a cautious low-speed test before driving normally.
Check your vehicle’s repair manual for exact specifications and fit.
