Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel where the squeaking is occurring.
Raise the vehicle with a jack and secure it on jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Check the thickness of the brake pads. If they are worn down to 3mm or less, they need replacement.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Apply brake grease to the backing of the new pads (avoid contact with the friction surface).
- Install the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for scoring or uneven wear; if present, replacement is necessary.
Replace Rotors:
- Remove the caliper bracket and the rotor by unscrewing the retaining screws (if equipped).
- Install the new rotor, ensuring it is properly seated against the hub.
- Reattach the caliper bracket.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer specifications.
Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Test the brakes gently before driving normally.
