Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen the lug nuts on the affected wheel before lifting the vehicle.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and secure it (do not let it hang by the brake line).
- Remove old brake pads and inspect for uneven wear. Replace with new pads if necessary.
Brake Rotors:
- Use a rotor puller if necessary to remove the rotor from the hub.
- Inspect the rotor for warping or scoring. If warped, replace with a new rotor.
- If the rotor is within specifications, consider resurfacing it if applicable.

4. Reassemble

Reattach the caliper with new or resurfaced rotors and pads.
Tighten caliper bolts to the manufacturer’s specified torque value (typically around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Test

Carefully lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer’s specifications (usually 75-90 ft-lbs).
Test drive the vehicle to ensure the problem is resolved.
