Tools and Materials:
- Brake caliper compression tool
- C-clamp or woodworking clamp
- Flathead screwdriver
- Brake cleaner
- New brake pads
Procedure:
1. Prepare the Vehicle:
- Engage the parking brake to keep the vehicle from rolling.
- Chock the wheels to ensure the vehicle is stable and won't move while you're working.
- Jack up the vehicle and support it securely using jack stands.
- Remove the lug nuts and take off the wheel to access the brake caliper.
2. Locate the Brake Caliper:
- The brake caliper is the housing that encloses the brake pads and piston. It's typically located on the back side of the wheel hub.
3. Remove the Caliper:
- Use a socket wrench to loosen and remove the bolts holding the brake caliper in place. Be careful not to damage the brake line.
- Once the bolts are removed, gently lift the caliper off the brake rotor. Be mindful of the brake fluid that may leak out.
4. Compress the Piston:
- Place the brake caliper compression tool over the piston. Make sure the tool is properly aligned with the piston.
- Use a C-clamp or woodworking clamp to turn the compression tool clockwise. This will gradually retract the piston back into the caliper.
- Continue turning the compression tool until the piston is fully retracted and you can easily insert the new brake pads.
5. Clean the Caliper:
- Inspect the caliper for any dirt, debris, or corrosion.
- Use a flathead screwdriver to carefully remove any stuck debris from the caliper.
- Spray the caliper with brake cleaner to thoroughly clean it. Ensure the cleaner evaporates completely before proceeding.
6. Install New Brake Pads:
- Take the new brake pads and position them in the caliper. Make sure the pads are properly seated in place.
- If necessary, use a small amount of brake grease on the back of the pads to prevent squeaking.
7. Reattach the Caliper:
- Carefully align the caliper over the brake rotor and slide it back into position.
- Secure the caliper with the bolts you removed earlier. Tighten the bolts snugly but do not overtighten.
8. Test the Brakes:
- Once the caliper is secured, slowly lower the vehicle off the jack stands.
- Gently press on the brake pedal several times to ensure the pads are properly engaged and the brakes are functioning correctly.
Note:
- Always check your vehicle's owner's manual for specific instructions and safety guidelines related to brake caliper maintenance.
- If you're uncomfortable performing this procedure, it's best to take your vehicle to a qualified mechanic.
