Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Use wheel chocks to prevent movement.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the braking components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts with a socket set.
- Carefully lift the caliper off the rotor.
- Inspect the brake pads for wear; replace if thickness is below 3mm.
Brake Rotors:
- Check rotors for uneven wear, scoring, or warping.
- If damaged, either resurface or replace the rotors.

4. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Apply brake grease to the backing plates of the new pads.
Install new brake pads, ensuring they are seated properly.

5. Reassemble Braking System

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to the manufacturer's specified torque (typically 20-30 ft-lbs).
Reinstall the wheel and tighten lug nuts in a star pattern to the specified torque (typically 80-100 ft-lbs).

6. Lower Vehicle and Test

Carefully lower the vehicle from the jack stands.
Test the brakes by pressing the pedal a few times to seat the pads.
Take the vehicle for a test drive to ensure the noise has been resolved.
