Steps
Raise and remove the wheel
Loosen the wheel nuts slightly on the ground, then lift and support the rear of the vehicle at approved points. Remove the wheel and keep the hardware together.
Check the brake assembly
Inspect pad thickness, rotor condition, hose routing, and the caliper for fluid leakage. Replace damaged friction parts in axle pairs when appropriate.
Disconnect the old caliper
Remove the caliper fasteners and lift the caliper from the bracket. Cap or plug the hose to limit fluid loss, then remove the hose connection without twisting the hose.
Fit the replacement caliper
Install the hose using new sealing washers and seat the connection squarely. Mount the caliper and pads or slides in their original arrangement; tighten fasteners to the vehicle specification.
Bleed and inspect the brakes
Bleed the opened circuit using the correct procedure and specified fluid. Check the hose and bleeder for leaks, then confirm the pedal becomes firm; do not drive with a soft pedal.
Reinstall the wheel and verify
Refit the wheel, lower the vehicle, and tighten the wheel nuts in a crossing pattern to specification. Pump the pedal, check fluid level, and perform a cautious low-speed brake check.
Check your vehicle’s repair manual for exact specifications and fit.
