Tools You'll Likely Need:
* Jack and jack stands
* Wheel chocks
* Lug wrench
* Socket wrench set (metric)
* Torque wrench
* Brake caliper piston compression tool
* C-clamp or similar tool (for caliper piston compression, if you don't have a specialized tool)
* Wire brush
* Brake cleaner
* New brake pads
* New rotors (often recommended when replacing pads)
* Possibly new caliper bolts (inspect for damage)
* Penetrating oil (like PB Blaster)
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the front wheels. Jack up the rear of the vehicle securely and support it with jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
3. Remove the Caliper:
* Locate the caliper mounting bolts. They are usually on the back of the caliper.
* Spray penetrating oil on the bolts if they're stubborn.
* Use the appropriate socket to remove the bolts.
* Carefully remove the caliper. You may need to support it with a bungee cord or wire to keep it from hanging by the brake line. Do not let the brake line hang freely.
4. Compress the Caliper Piston:
* Use a caliper piston compression tool to push the piston back into the caliper bore. This creates space for the new, thicker brake pads. A C-clamp can be used, but a specialized tool is safer and more effective. Be careful not to damage the piston seal. Turn the piston slowly and evenly.
5. Remove the Old Brake Pads: The old brake pads should now be easily removable. Inspect the caliper bracket and slide pins for wear or damage. Clean them thoroughly. Lubricate the slide pins with brake caliper grease (not regular grease).
6. Replace the Rotors (Optional but Recommended): If the rotors are worn or scored, replace them now. They are usually secured with bolts or screws.
7. Install the New Brake Pads: Carefully install the new brake pads into the caliper bracket.
8. Install the Caliper: Reinstall the caliper onto the caliper bracket, making sure the pads are correctly seated. Tighten the mounting bolts to the manufacturer's specified torque.
9. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts.
10. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Torque Lug Nuts: Use a torque wrench to tighten the lug nuts to the manufacturer's specifications.
12. Pump the Brakes: Pump the brake pedal several times to ensure the brakes are working properly. Have someone pump the brakes while you monitor the fluid level in the master cylinder; top off as necessary.
13. Test Drive: Take a short test drive to verify the brakes are functioning correctly.
Important Notes:
* Brake fluid is corrosive and can damage paint. Be careful when handling it.
* Bleeding the brakes may be necessary if you've opened the brake system. This is a more advanced procedure; if you are unfamiliar with bleeding brakes, consult a professional.
* Always consult your vehicle's repair manual for specific torque specifications, part numbers, and detailed instructions. Improperly installed brakes can be dangerous.
* If you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. Brake repair is crucial for safety.
