This is a general guide. Always consult your vehicle's repair manual for specific instructions and torque specifications. These specifications are crucial for safety.
Tools You'll Need:
* Jack and jack stands (Safety First: Never work under a car supported only by a jack)
* Lug wrench
* Wheel chocks
* Socket wrench and sockets (various sizes, including likely 15mm and 13mm for caliper bolts and possibly others)
* C-clamp or brake caliper compression tool
* Wrench for brake line bleeder screw
* Brake cleaner
* New brake pads
* New rotors (if needed – inspect for wear and scoring)
* Possibly a caliper rebuild kit (if calipers are seized or leaking)
* Penetrating oil (like PB Blaster)
* Gloves
* Safety glasses
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and chock the front wheels. Raise the vehicle using the jack and securely support it with jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Inspect the Brakes: Carefully inspect the brake pads for wear. Replace them if they're worn below the minimum thickness (check your owner's manual or parts store). Inspect the rotors for scoring, grooves, or excessive wear. If damaged, they need to be replaced.
4. Compress the Caliper Piston: Using a C-clamp or brake caliper compression tool, carefully compress the caliper piston. This will give you enough space to install the new brake pads. Be careful not to damage the piston seal. Some pistons rotate while compressing.
5. Remove the Brake Pads: Usually, there are pins or clips holding the brake pads in place. Remove these to release the old pads. Clean the caliper and slider pins thoroughly with brake cleaner.
6. Lubricate and Install: Lightly lubricate the caliper slider pins with brake caliper grease (Do not use general purpose grease). Install the new brake pads.
7. Reinstall the Wheel: Make sure everything is in place. Put the wheel back on and tighten the lug nuts.
8. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
9. Bleed the Brakes (Important!): Because you've disturbed the brake system, you'll likely need to bleed the brakes to remove any air that may have entered the lines. This is crucial for proper braking performance. You'll need a second person to help with this step, or use a pressure bleeder. Consult your owner's manual for bleeding procedure.
Important Considerations:
* Rotor Replacement: If your rotors are worn, scored, or excessively rusty, replace them. They need to be resurfaced or replaced if the minimum thickness has been reached.
* Caliper Issues: If the calipers are seized, leaking, or otherwise damaged, you may need to replace them or rebuild them with a caliper rebuild kit. This is a more involved repair.
* Brake Fluid: Check your brake fluid level regularly, and top it off if needed. Brake fluid absorbs moisture over time, so it's a good idea to flush and replace the brake fluid periodically.
Disclaimer: This is a general guide. The exact procedure may vary slightly depending on your specific vehicle. Always consult your vehicle's repair manual for detailed instructions and safety precautions. Improper brake repair can be extremely dangerous. If you're unsure about any step, it's best to seek professional help from a qualified mechanic.
