- Tools:
- Socket set
- Brake pad spreader/C-clamp
- Flathead screwdriver
- Pliers
- Materials:
- New rear brake pads (specific to your vehicle)
- Brake fluid
- Cleaning supplies
Instructions:
1. Safety First:
- Ensure the vehicle is in "Park" and the engine is turned off.
- Engage the parking brake.
- Lift the rear of the vehicle using jack stands or a car lift for safe access to the wheels.
- Locate the brake fluid reservoir and open it.
2. Remove the Wheel:
- Use the socket set to loosen and remove the lug nuts holding the wheel in place.
- Remove the wheel and set it aside.
3. Remove the Caliper:
- Locate the caliper and remove the two guide pins holding it to the caliper bracket.
- Carefully remove the caliper by pulling it away from the rotor.
- Rest the caliper on a stable surface, ensuring the brake line is not stretched or damaged.
4. Remove Old Brake Pads:
- There will be two brake pads (inner and outer) held by retaining clips.
- Lift the brake pad away from the rotor to release it from the retainer, and then pull it out.
- Remove both the outer and inner brake pads.
5. Inspect the Rotor:
- While the brake pads are out, check the brake rotor for any wear, grooves, or other signs of damage. If necessary, the rotor may also need replacement.
6. Compress the Piston (Using C-Clamp Method):
- Use a C-clamp or brake pad spreader specifically designed for compressing brake pistons.
- Place the spreader between the brake pads and the old piston.
- Slowly rotate the spreader's screw mechanism to compress the piston back into the caliper housing.
7. Install New Brake Pads:
- Insert the new brake pads into the caliper, ensuring the backing plate is properly seated.
- Secure the brake pads with the retaining clips or guide pins if applicable.
8. Reinstall the Caliper:
- Carefully reinstall the caliper over the rotor, aligning it with the pin guides.
- Secure the caliper with the removed guide pins.
- Tighten the guide pins to the specified torque.
9. Reinstall the Wheel:
- Replace the wheel onto the lug nuts and tighten them by hand.
- Lower the vehicle back to the ground, ensuring the parking brake is still engaged.
- Use the socket set to tighten the lug nuts in a star pattern with the specified torque.
10. Refill the Brake Fluid Reservoir (If Necessary):
- If you had to compress the piston back into the caliper, the brake fluid level in the reservoir may have dropped.
- Check the level and if needed, slowly top it off with the same type of brake fluid as recommended for your vehicle.
11. Test the Brakes:
- Before driving, gently apply the brakes to ensure the brake pedal feels firm and functions properly.
Remember, if you're not comfortable with any of the above steps or encounter any difficulties during the process, it's best to seek professional assistance from a qualified mechanic. The brake system directly impacts your safety while driving, so proper installation and maintenance are crucial.
