Procedure:
1. Prepare your vehicle.
- Engage the parking brake.
- Loosen the lug nuts on the rear wheels, but do not remove them completely.
2. Lift up your vehicle.
- Place the jack under the appropriate lifting point on the rear of your vehicle and raise it up until the rear wheels are off the ground.
3. Remove the lug nuts and wheel.
- Remove the lug nuts completely and take off the wheel.
4. Remove the brake caliper.
- Locate the brake caliper, which is the assembly that holds the brake pads and is mounted to the wheel hub.
- Use a socket wrench to remove the bolts that secure the brake caliper to the wheel hub.
- Carefully lift off the brake caliper and hang it out of the way with a bungee cord or string.
5. Remove the old brake disc.
- The brake disc should now be exposed.
- Use a socket wrench to remove the bolts that secure the brake disc to the wheel hub.
- Slide off the old brake disc.
6. Clean the brake hub.
- Use a wire brush and brake cleaner to clean the brake hub and remove any dirt, grease, or rust that may affect the performance of the new disc and pads.
7. Install the new brake disc.
- Slide the new brake disc onto the wheel hub.
- Make sure that the disc is properly seated and aligned.
- Reinstall the bolts and tighten them securely.
8. Reinstall the brake caliper.
- Carefully lift the brake caliper back into position and align the mounting holes.
- Reinstall the bolts and tighten them securely.
9. Compress the brake piston.
- Use a brake caliper wind-back tool to compress the brake piston.
- This will allow you to fit the new brake pads.
10. Install new brake pads (if needed).
- If you're replacing the brake pads, now is the time to do it.
- Check your vehicle's specific repair manual or online guides for instructions on how to do so.
11. Bleed the brakes.
- If you compressed the brake piston, you'll need to bleed the brakes to remove any air from the system.
- Consult your vehicle's repair manual or online guides for instructions on how to do so.
12. Reinstall the wheel and lug nuts.
- Position the wheel back onto the wheel hub.
- Reinstall the lug nuts and tighten them in a star pattern, tightening them a bit at a time until they are snug.
13. Lower the vehicle.
- Carefully lower the vehicle using the jack.
14. Test the brakes.
- Once the vehicle is back on the ground, press the brake pedal a few times to ensure the brakes are working properly.
Note:
- This guide is general and may vary depending on your specific vehicle model. It's important to refer to the repair manual or specific instructions for your vehicle. If you're not confident in performing this task, it's best to seek the help of a qualified mechanic. Brake work is crucial for your safety, and any mistakes can have serious consequences.
