Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface.
Use wheel chocks to prevent movement.
Lift the vehicle using a jack and secure with jack stands.

2. Remove Wheel

Use a socket set to remove the lug nuts from the wheel.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; they should be at least 3mm thick.
- Look for uneven wear or cracks.
Replace Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and support it using a bungee cord (do not let it hang by the brake line).
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for uneven wear, scoring, or rust.
Replace Rotors:
- Remove the caliper bracket (if necessary) to access the rotor.
- Remove the old rotor from the hub.
- Clean the hub surface and install the new rotor.
- Torque the rotor to manufacturer specifications.

5. Reassemble and Test

Reattach the caliper and tighten the bolts to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a star pattern.
Lower the vehicle and pump the brake pedal to ensure proper contact with the pads.
Test drive the vehicle to ensure the noise is resolved.
