Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Loosen lug nuts slightly before raising the vehicle.
Use a jack to lift the vehicle and place jack stands for safety.
Remove the wheel completely to access brake components.

3. Inspect and Replace Components

Brake Rotors:
- Measure rotor thickness with a micrometer; replace if below specifications.
- Check for warping using a dial indicator; replace if warped beyond tolerance.
Brake Pads:
- Inspect for even wear; replace if worn unevenly or below minimum thickness.
- Clean caliper mounting brackets with brake cleaner.

4. Reassemble

Reinstall Components:
- Install new rotors and brake pads if necessary.
- Reinstall the wheel and hand-tighten lug nuts.
Lower Vehicle:
- Carefully lower the vehicle and remove the jack stands.
- Torque lug nuts to the manufacturer’s specifications (usually around 80-100 lb-ft).

5. Final Checks

Reconnect the battery and check for any warning lights.
Test brake function before driving.
