Solution

1. Preparation

Gather required tools and materials.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

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 to ensure safety.

3. Remove Wheel

Use a lug wrench to remove the wheel(s) for access to the brake components.
Place the removed wheel in a safe location.

4. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket wrench.
Slide the caliper off the rotor and support it to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Check the backing plates for damage; replace if necessary.
Install new brake pads, ensuring they are properly aligned.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for scoring and thickness; replace if they are below the manufacturer's minimum thickness or damaged.
Use a rotor removal tool if necessary to remove the rotors.
Clean the hub surface before installing new rotors to ensure proper fit.

6. Reassemble Components

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque settings.
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle from the jack stands with the jack.
Fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
