Solution

1. Preparation

Gather necessary tools and materials.
Tools Required: Socket set, torque wrench, brake cleaner, multimeter, jack and jack stands, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts on the affected wheel while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel by fully unscrewing the lug nuts.

3. Inspect and Clean

Inspect Brake Pads and Rotors:
- Check the thickness of the brake pads; replace if below manufacturer specifications.
- Inspect the rotors for any grooves or excessive wear.
Clean Components:
- Use brake cleaner to remove dust and debris from the brake pads and rotors.
- Wipe down the calipers and remove any rust or buildup.

4. Replace Brake Pads and/or Rotors (if necessary)

Replace Brake Pads:
- Remove the caliper bolts and gently lift the caliper away from the rotor.
- Slide out the old brake pads and replace them with new ones.
- Reattach the caliper and torque the bolts to manufacturer specifications (usually around 25-30 ft-lbs).
Replace Rotors (if needed):
- Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
- Install the new rotor, ensuring it is seated properly.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to manufacturer specifications (usually around 100-110 ft-lbs).
Test the brakes gently to ensure proper function before driving.
