Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks around the rear wheels.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts of the front wheel where the noise is occurring.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are below 3 mm, replace them.
Remove Brake Caliper:
- Use a socket set to remove the caliper bolts. Support the caliper with a bungee cord to avoid strain on the brake line.
Replace Brake Pads:
- Slide out the old pads and install new pads. Ensure any shims are in place.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotor Condition:
- Measure rotor thickness with a caliper. Replace if below manufacturer specifications or if they are warped/scored.
Remove Brake Rotor:
- Remove any retaining screws and slide the rotor off the hub.
Install New Rotor:
- Clean the hub surface, position the new rotor, and secure it with screws.

5. Reassemble and Test

Reattach the brake caliper over the new pads, tightening to manufacturer torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Repeat on the other side if necessary or as part of routine maintenance.
