Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Raise the vehicle using a jack and secure it with jack stands.

2. Remove Wheels

Use a lug wrench to loosen the lug nuts on the front or rear wheels where the noise is occurring.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
- Inspect the brake pads for wear; if they are worn down to the indicators, replace them.
- If replacing, remove the old pads and install new ones, ensuring they are seated correctly.
- Apply brake grease to the back of the pads to prevent noise.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the surface of the rotor for grooves or scoring.
- If damaged, remove the rotor by unscrewing the retaining screws or bolts.
- Replace with a new rotor, ensuring it is properly aligned and secured.

5. Reassemble Brake Components

Sub-steps:
- Reattach the caliper over the new pads and rotor, securing it with the caliper bolts to the manufacturer’s torque specifications.
- Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and tighten the lug nuts in a crisscross pattern to the specified torque.
Pump the brake pedal a few times to seat the new brake pads properly.
