- 17mm socket
- 13mm socket
- Flat-head screwdriver
- Jack
- Jack stands
- Wheel chocks
- Safety goggles
2. Safety First:
- Park the car on a level surface, turn off the engine, and engage the parking brake. Use wheel chocks to secure the front wheels.
3. Remove the Rear Wheels:
- Use the 17mm socket to loosen and remove the lug nuts on one of the rear wheels.
- Place a jack under the car, near the rear wheel you are working on, and raise the vehicle until the tire is off the ground.
- Secure the jack with jack stands.
- Remove all lug nuts and the rear wheel.
4. Remove the Brake Caliper:
- Locate the brake caliper, which is connected to the rear brake disc.
- Use the 13mm socket to remove the two bolts holding the caliper in place.
- Carefully lift the caliper off the brake disc and suspend it using a piece of wire or string. Make sure not to damage the brake line.
5. Remove the Brake Disc:
- Inspect the condition of the old brake disc. Look for deep grooves or significant wear.
- Use the flat-head screwdriver to pry out the two retaining screws holding the brake disc to the hub.
- Gently pull the brake disc off the hub.
6. Clean and Inspect:
- Clean the hub thoroughly to remove any dirt or debris.
- Inspect the hub for any damage, such as deep scratches or pitting. If necessary, replace the hub.
7. Install New Brake Disc:
- Position the new brake disc onto the hub, ensuring it sits correctly.
- Thread and tighten the two retaining screws back into the hub.
8. Reinstall the Brake Caliper:
- Carefully place the brake caliper back over the brake disc.
- Secure the caliper with the two bolts previously removed. Tighten the bolts securely.
9. Reinstall the Wheel:
- Place the rear wheel back onto the hub. Hand-tighten the lug nuts.
- Lower the car off the jack stands, then remove them.
- Tighten the lug nuts with the 17mm socket in a star pattern to an appropriate torque.
10. Repeat on the Other Side:
- Repeat steps 3-9 for the other rear wheel.
11. Test the Brakes:
- Gently depress the brake pedal several times to ensure that the brakes are functioning properly.
Remember, if you are not confident or comfortable performing this procedure yourself, it is best to seek assistance from a qualified mechanic or automotive specialist.
