Tools Needed:
- Jack and jack stands
- Lug wrench
- Socket wrench
- Flat-head screwdriver
- C-clamp
- New brake pads
- Brake grease
Steps to Replace Rear Brake Pads:
1. Park your car on a level surface and engage the parking brake. Make sure the car is in 'Park' if it's an automatic transmission. For safety, you can chock the front wheels to prevent the car from rolling.
2. Loosen the lug nuts on the rear wheels. Don't remove them completely at this point.
3. Jack up the car and secure it with jack stands. Make sure the jack stands are placed on sturdy parts of the car frame. Lift the car high enough so that the rear tires are off the ground.
4. Remove the lug nuts and take off the rear wheels. Now, you can completely remove the lug nuts and pull the wheels straight toward you to remove them.
5. Locate the brake caliper. It's the metal housing that encases the brake pads and the caliper piston.
6. Use a flat-head screwdriver to pry open the caliper pins' dust boots. This will expose the hex heads of the caliper pins.
7. Loosen the caliper pins using a socket wrench. Remove the pins and lift the caliper assembly off the rotor. Be careful not to let the caliper hang by the brake line; use a zip tie or bungee cord to hang it from the suspension for support.
8. Inspect the rotor for any damage or excessive wear. If the rotor is severely worn or damaged, you may need to replace it as well.
9. Push the caliper piston back into the caliper housing using a C-clamp. This will create space for the new brake pads.
10. Install the new brake pads. Make sure the new brake pads are positioned correctly and seated properly. Lightly apply brake grease to the metal backing of the brake pads. This helps reduce brake squeal.
11. Replace the caliper assembly and secure it with the caliper pins. Tighten the caliper pins snugly.
12. Reinstall the rear wheels and lug nuts. Hand-tighten the lug nuts first, then use the lug wrench to tighten them in a star pattern until they are snug.
13. Lower the car and remove the jack stands.
14. Test the brakes by depressing the brake pedal a few times. Ensure the brakes feel firm and responsive before driving.
Additional Notes:
- If you're not comfortable working on your brakes or don't have the necessary tools, it's best to have the brake pads replaced by a qualified mechanic.
- Brake dust and brake fluid can be harmful if ingested or absorbed through the skin, so it's essential to wear gloves and eye protection when handling these components.
- While replacing rear brake pads, it's a good idea to inspect the brake rotors and other components of the braking system for wear and damage. If necessary, you may also want to replace these parts to ensure optimal braking performance.
