Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Loosen lug nuts using a socket set while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads. If they are below 3mm, they need replacement.
Replacement:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor. Support it with a bungee cord or hang it to avoid strain on the brake line.
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly aligned.
- Reinstall the caliper over the new pads and tighten caliper bolts to manufacturer specifications (typically 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, they should be replaced.
Remove the caliper bracket by unscrewing the bolts.
Slide off the rotor; if it's stuck, tap gently with a rubber mallet.
Install new rotors and ensure they are properly seated.
Reinstall the caliper bracket.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts to the specified torque (usually 75-90 ft-lbs).
Pump the brake pedal to ensure pads seat properly before driving.
Test drive the vehicle to confirm the noise has stopped.
