Here's a general outline. This is not a comprehensive guide and may not cover all variations. Always refer to a repair manual for your specific vehicle year and model:
Tools You'll Likely Need:
* Jack and jack stands (SAFETY FIRST! Always use jack stands, never rely solely on a jack.)
* Wheel chocks
* Lug wrench
* Socket wrench set (metric)
* Brake caliper compression tool
* Wrenches (metric)
* C-clamp or similar tool (for piston compression, if needed)
* Brake cleaner
* New brake pads and potentially rotors (inspect the rotors for wear before starting)
* Gloves
* Safety glasses
Steps (General):
1. Safety First: Park on a level surface, engage the parking brake, and chock the front wheels. Raise the rear of the vehicle securely using the jack and jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Caliper: You'll likely need to remove caliper bolts (usually 14mm or 17mm) holding the caliper to the caliper bracket. Sometimes you need to compress the brake caliper piston to provide clearance for the new pads. Use a caliper compression tool—this is crucial to avoid damage. Carefully support the caliper with a bungee cord or wire to prevent it from hanging by the brake line.
4. Remove the Brake Pads: The pads should now be accessible. They're usually held in place by clips or pins. Carefully remove the old pads. Inspect the pad wear indicators.
5. Inspect the Rotors: Carefully inspect the brake rotors for wear, scoring, or excessive rust. If they're worn or damaged, they need to be replaced.
6. Reinstall the Brake Pads: Install the new brake pads, ensuring they're seated correctly.
7. Reinstall the Caliper: Carefully reinstall the caliper onto the caliper bracket, ensuring the bolts are tightened to the manufacturer's specifications (consult your repair manual).
8. Bleed the Brakes (Important!): After working on the brakes, it's crucial to bleed the brakes to remove any air that may have entered the system. This is best done with a helper. You'll need a wrench to open the bleeder valve on the caliper and a hose to collect the fluid. Again, consult your repair manual for the proper bleeding procedure.
9. Reassemble: Reinstall the wheel and tighten the lug nuts to the correct torque specification (consult your repair manual). Lower the vehicle.
10. Test the Brakes: Before driving, carefully test the brakes several times to ensure they are functioning properly.
