Solution

1. Preparation

Gather tools and safety equipment: gloves, safety glasses, and a floor jack.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel where the squeaking is suspected.
Lift the vehicle with a floor jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake pads for wear; they should be no less than 3mm thick.
Check the rotors for any scoring or irregularities and use a rotor gauge if necessary.
Look for signs of rust or debris on the brake components.

4. Replace Brake Pads (if necessary)

If brake pads are worn:
- Remove the caliper bolts with a socket wrench and carefully slide the caliper off.
- Replace old brake pads with new ones, ensuring they are properly seated.
- Use high-temperature brake grease on the back of the pads to reduce noise.

5. Reassemble and Test

Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s specified torque settings.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications.
