1. Gather Proper Tools:
- Floor Jack & Jack Stands
- 17mm hex/Allen key
- Wheel chock or parking break to prevent car from rolling
- Lug wrench to remove wheel lug nuts
- C-clamp or caliper wind-back tool
- Safety goggles and gloves
2. Prepare the Car:
- Engage parking break.
- Chock the front wheels.
- Jack up your car at a designated jacking point.
- Securely place the car on jack stands.
3. Remove the Wheel:
- Loosen the lug nuts on the rear wheel you're working on, but don't remove them completely yet.
- Jack the car up until the tire is off the ground.
- Remove lug nuts and take off the wheel.
4. Access the Caliper:
- Locate the brake caliper behind the wheel.
5. Remove caliper:
- Remove the bolts holding the caliper to its mounting bracket.
- Check for any signs of uneven or excessive wear on the brake pads and rotors.
- Use a C-clamp (or similar tool) to slowly depress the caliper piston towards the caliper body to make more room for removal.
- Lift off the caliper and place it aside; be cautious not to strain the brake line.
6. Remove the brake disc:
- Use the 17mm hex key to turn and remove the retaining hex bolt on the rear of the disc (or any bolts that hold the rotor to the hub).
- Once free, slide off the brake disc.
7. Clean and Inspect:
- Inspect the disc for grooves or excessive wear.
- Also check the hub and caliper assembly for any issues.
- Clean both surfaces with brake cleaner and/or wire brush (if needed).
8. Reinstall:
- Slide the new or cleaned disc back in place.
- Install the retaining bolt onto the disc and tighten it securely.
- Reattach the caliper and insert the mounting bolts, tightening securely.
- Replace the wheel and lug nuts but do not tighten fully.
- Lower the car but leave it jacked up off the ground.
- Lightly press the brake pedal a few times to seat the pads and pistons properly.
- Tighten the lug nuts further while the car is still jacked up.
- Lower the car gently to the ground.
- Tighten the lug nuts one last time.
9. Test Brakes:
- Test drive gently and carefully. Apply the brakes firmly to check that everything functions as expected.
Remember, if you're unsure or uncomfortable performing any maintenance or repairs, it's best to seek assistance from a qualified mechanic.
