Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making noise.
Secure the vehicle with jack stands.
Remove the wheel using a lug wrench.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor; support it to prevent strain on the brake line.
- Check the brake pads for thickness; replace if less than 1/8 inch.
Replace Brake Pads:
- Remove old pads from the caliper bracket.
- Install new pads, ensuring they fit snugly into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Brake Rotors:
- Check for grooves or warping on the rotor surface.
- Use a micrometer to measure rotor thickness.
Replace Rotors:
- Remove the caliper bracket bolts and take off the bracket.
- Slide the rotor off the hub; if stuck, gently tap with a rubber mallet.
- Install new rotor, ensuring it is properly seated.

5. Reassemble and Test

Reattach the caliper bracket and caliper, tightening bolts to manufacturer specifications (typically 20-30 ft-lbs).
Reinstall the wheel and lower the vehicle.
Pump the brake pedal several times to seat the pads and check brake fluid level.
Test drive the vehicle at low speed to ensure the noise is gone.
