Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Ensure the vehicle is parked on a flat surface and the engine is off.
Engage the parking brake and wear safety goggles for protection.

2. Raise the Vehicle

Loosen the lug nuts on the affected wheel slightly while the vehicle is still on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel completely after fully loosening the lug nuts.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Remove the brake caliper by unscrewing the bolts with a socket wrench. Check the thickness of the brake pads.
Replace Brake Pads: If pads are worn down (less than 3mm), replace them. Remove the old pads, and install new pads ensuring they are seated properly.
Tools Required for this Step: Socket set, brake grease.

4. Check and Resurface Brake Rotors

Inspect Rotors: Check the rotors for any grooves or scoring. If damaged, they may need to be resurfaced or replaced.
Resurface or Replace: If the rotors are within spec, you can resurface them; otherwise, replace them with new rotors.
Tools Required for this Step: Torque wrench, brake cleaner.

5. Reassemble and Test

Reattach the brake caliper, ensuring it operates smoothly without binding. Tighten the caliper bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and torque the lug nuts to the specified value.
Start the vehicle and test the brakes at low speed to ensure the noise is eliminated.
