Tools and Materials Needed:
- Jack and jack stands
- Socket wrench or impact wrench
- Metric socket set
- C-clamp or large pliers
- Flathead screwdriver or brake caliper tool
- Brake cleaner
- New brake pads
- New brake rotors (if necessary)
- Brake grease
Before You Begin:
- Engage the parking brake and chock the rear wheels to ensure the vehicle stays in place during the repair.
- Consult your vehicle owner's manual to verify any specific precautions or procedures for your car model.
Procedure:
1. Loosen the Lug Nuts: Use a lug wrench or impact wrench to loosen the lug nuts on the front wheels, but do not remove them completely.
2. Raise the Vehicle: Position a jack under the designated lift point on the front of the vehicle and raise it until the affected wheel is off the ground. Support the vehicle securely with jack stands.
3. Remove the Wheel: Unscrew and remove the lug nuts, then gently pull the wheel towards you to disengage it from the hub. Set the wheel aside safely.
4. Remove the Brake Caliper Assembly:
- Using the appropriate socket wrench and sockets, remove the bolts holding the brake caliper in place.
- Be careful not to let the caliper hang by the brake line. Rest it securely on the steering knuckle or control arm to prevent damage.
5. Inspect the Brake Components:
- Remove the old brake pads from the caliper.
- Examine the brake rotors for wear or damage. Replace them if necessary.
6. Clean the Caliper: Spray the interior of the brake caliper with brake cleaner to remove dirt and debris.
7. Apply Brake Grease: Apply a thin coat of brake grease to the new brake pad backing plates where they contact the caliper. This ensures smooth movement and prevents squealing.
8. Replace the Brake Pads: Slide the new brake pads into the caliper and insert the anti-rattle shims, if provided with your new brake pads.
9. Reinstall the Caliper Assembly: Position the caliper over the brake pads and reattach it using the bolts you removed earlier. Tighten securely.
10. Replace the Wheel: Reattach the wheel by hand-tightening the lug nuts. Lower the vehicle and thoroughly tighten the lug nuts in a star pattern using a lug wrench or impact wrench.
11. Perform a Brake Test:
- Test the brakes by gently applying pressure to the brake pedal. Verify that the pedal feels firm and the vehicle stops safely.
Additional Tips:
- If you don't have experience performing brake work, it's a good idea to consult a professional mechanic to ensure the repairs are done correctly.
- Brake fluid may leak out while you remove the caliper, so have a container ready to catch the fluid.
- Dispose of the old brake pads and brake fluid properly as they may be contaminated.
Remember, brake repairs are crucial for your safety on the road, so if you are uncertain about any part of the process, it's better to seek professional assistance.
