Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Set the parking brake and wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket using a socket set.
Slide the caliper off the rotor, supporting it with a bungee cord to avoid strain on the brake line.
Inspect the brake pads for wear. If they are worn down to the metal, replace them.
Install new brake pads, ensuring they are correctly oriented.

5. Inspect and Resurface/Replace Rotors

Check the rotors for any visible damage.
If the rotors are scored or warped, either resurface them or replace with new rotors.
Clean the rotor surface with brake cleaner before assembly.

6. Reassemble Brake Components

Reattach the caliper over the new brake pads and torque the caliper bolts to manufacturer's specifications (typically 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle and Test

Carefully lower the vehicle and remove jack stands.
Tighten the lug nuts to the correct torque specification (typically 100-120 ft-lbs).
Pump the brake pedal to ensure proper brake pad seating before test driving.
