Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear protective gloves and eyewear.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the rear or front wheel where the noise is originating using a lug wrench.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper by unscrewing the caliper bolts with a socket set.
2. Slide the caliper off the rotor and support it with a hanger or bungee cord to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pads for thickness; replace if they are below manufacturer specifications (usually around 3mm).
5. Apply brake grease to the back of the new pads and install them into the caliper bracket.

4. Inspect Brake Rotors

Sub-steps:
1. Check the surface of the rotor for grooves or damage.
2. If warped, replace the rotor with a new one; if not, clean the surface with brake cleaner and a non-abrasive pad.
3. Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).

5. Reassemble

Sub-steps:
1. Put the wheel back on and hand-tighten the lug nuts.
2. Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically 100-120 ft-lbs).
3. Repeat the process for the opposite side if needed.
4. Finally, check the brake fluid level and top off if necessary.
