Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Raise Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle with jack stands.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the braking components.

4. Inspect and Replace Brake Pads

Inspection:
- Check the brake pads for wear; replace if less than 3mm thick.
- Look for uneven wear or damage to the pads.
Replacement:
- Remove caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord or rope.
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring proper orientation.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically around 20-30 lb-ft).

5. Inspect and Replace Rotors (if necessary)

Inspection:
- Check rotors for grooves or scoring; replace if deeper than 0.5mm.
Replacement:
- Remove the caliper bracket if necessary.
- Unbolt and remove the rotor.
- Install the new rotor, ensuring it is properly seated.
- Reassemble caliper and bracket.

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle off the jack stands and torque the lug nuts to manufacturer specifications (typically around 80-100 lb-ft).
