Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Wear safety glasses and gloves for protection.

2. Remove Wheel

Loosen the lug nuts on the wheel where the noise is occurring using a socket wrench.
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 Pads: Check the thickness of the brake pads; if below 3mm, replace them.
Remove Pads: Use a caliper tool to retract the caliper piston, then remove the caliper bolts using a socket set.
Replace Pads: Slide out the old pads and replace them with new ones, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors: Measure rotor thickness with a micrometer; if below specifications or damaged, replace them.
Remove Rotors: If replacing, remove the caliper bracket and then the rotor.
Install New Rotors: Place the new rotor onto the hub and secure it.

5. Reassemble and Bleed Brakes

Reattach the caliper and caliper bracket using the specified torque settings (typically 25-35 ft-lbs).
Replace the wheel and lug nuts, tightening them in a star pattern.
Bleed the brake system to remove any air that may have entered during the repair.
