Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts with a socket set.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and wheel to access the braking components.

3. Inspect Brake Components

Brake Pads:
- Remove the brake caliper by unbolting it from the bracket.
- Check the thickness of the brake pads; replace if below the manufacturer's minimum specification (usually around 3mm).
Brake Rotors:
- Inspect the rotors for grooves, cracks, or excessive wear. If damaged, replace the rotors.
- Measure rotor thickness with a micrometer; replace if below minimum thickness.

4. Replace Components

Brake Pads:
- If replacement is necessary, install new brake pads according to the manufacturer’s specifications.
Brake Rotors:
- If rotors are replaced, ensure they are cleaned with brake cleaner before installation.
- Torque rotor mounting bolts to the manufacturer’s specifications.

5. Reassemble Braking System

Reattach the brake caliper over the new pads and rotors.
Tighten caliper bolts to the specified torque value.
Reinstall the wheel and hand-tighten the lug nuts.

6. Test Brake System

Lower the vehicle and tighten the lug nuts to the specified torque.
Pump the brake pedal several times to seat the new pads.
Perform a test drive to ensure the noise is gone and braking is effective.
