Tools You'll Need:
* Jack and jack stands (essential for safety!)
* Lug wrench
* Wheel chocks
* Socket wrench set (metric) with extensions and ratchets
* Brake caliper C-clamp or brake caliper compression tool (essential to retract the piston)
* Pliers or a wire brush (to clean brake parts)
* New brake pads
* New rotors (recommended, but sometimes reusable; inspect carefully)
* Penetrating lubricant (like PB Blaster)
* Torque wrench (highly recommended)
* Gloves
* Safety glasses
Steps:
1. Safety First: Park on a level surface, engage the parking brake firmly, and use wheel chocks on the rear wheels. Jack up the front of the vehicle and securely support it on jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts using the lug wrench. Then, carefully remove the wheel.
3. Remove the Caliper:
* Locate the caliper mounting bolts. They are usually on the back of the caliper.
* Spray penetrating lubricant on the bolts if they're stubborn.
* Use the appropriate socket to remove the bolts.
* Carefully remove the caliper. It may be easier to hang it from the suspension using a piece of wire or a bungee cord to keep it out of the way and prevent damage to the brake line. Do not let the brake line hang freely.
4. Compress the Caliper Piston: Use a C-clamp or caliper compression tool to push the caliper piston back into the caliper housing. This creates space for the new, thicker brake pads. You'll need to turn the piston as you compress it. Be careful not to damage the piston or boot.
5. Remove the Old Brake Pads: The old brake pads should simply slide out from the caliper.
6. Inspect and Replace Rotors (Optional but Recommended): Inspect the rotors for scoring, grooves, or excessive wear. If they are worn or damaged, replace them. If reusing rotors, clean them thoroughly with a wire brush.
7. Install New Brake Pads: Slide the new brake pads into the caliper.
8. Install the Caliper: Carefully reinstall the caliper onto the mounting brackets. Tighten the mounting bolts to the manufacturer's specified torque.
9. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts. Do not fully tighten them yet.
10. Lower the Vehicle: Carefully lower the vehicle to the ground using the jack.
11. Tighten Lug Nuts: Fully tighten the lug nuts in a star pattern to ensure even pressure.
12. Repeat for the Other Side: Repeat steps 2-11 for the other front wheel.
13. Test Brakes: Before driving, pump the brake pedal several times to ensure the brakes are working properly. Take the vehicle for a short test drive, and ensure you feel a firm and responsive brake pedal. If anything feels off, have a professional inspect your brakes immediately.
Important Considerations:
* Bleeding the Brakes: In most cases, you don't need to bleed the brakes after changing the pads, but if you have any concerns or if the brake pedal feels spongy, it's a good idea to bleed them. This is best done with a second person. See your owner's manual or an online resource for bleeding procedures.
* Brake Fluid: Check your brake fluid level in the master cylinder. Top off if necessary.
* Torque Specifications: Always consult your vehicle's repair manual for the correct torque specifications for lug nuts and caliper bolts. Using the wrong torque can damage your vehicle.
* Professional Help: If you're uncomfortable performing any of these steps, take your vehicle to a qualified mechanic. Brakes are a critical safety system, and improper installation can have serious consequences.
This guide provides a general overview. Always consult your vehicle's repair manual for specific instructions and diagrams. Remember safety is paramount. If you are not experienced with automotive repair, it is strongly recommended to seek professional help.
