Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel corresponding to the affected brake.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for wear; if less than 1/8 inch thick or damaged, replace them.
Brake Rotors:
- Check the rotor surface for any scoring or grooves.
- If damaged, replace the rotors. If they are in good condition, clean them with brake cleaner.

4. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Apply brake grease to the back of the new pads (avoid contact with the pad surface).
Install the new brake pads into the caliper bracket.

5. Reassemble and Test

Reinstall the caliper over the new brake pads and tighten the caliper bolts to the manufacturer’s specified torque (typically 25-35 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a crisscross pattern.
Lower the vehicle and ensure that the brake pedal feels firm before taking the vehicle for a test drive.
