Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Brake cleaner
- Torque wrench
- Socket set
- C-clamp or brake caliper tool
Safety Warnings:
- Ensure the vehicle is on a flat surface before lifting.
- Use jack stands to support the vehicle securely.

2. Remove Wheel

Loosen the lug nuts on the affected wheel with a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake assembly.

3. Inspect Brake Components

Brake Pads: Check the thickness of the brake pads. Replace if less than 3mm.
Brake Rotors: Inspect for warping or scoring. If damaged, replace them.
Calipers: Ensure calipers are not sticking. If they are, clean and lubricate the slide pins.

4. Clean and Lubricate

Use brake cleaner to remove dust and debris from the brake pads, rotors, and calipers.
Apply brake lubricant to the back of the brake pads and on the caliper slide pins to prevent squeaking.

5. Reassemble and Install Wheel

Place the brake components back in their original position.
Reinstall the wheel, hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs for Model 3).

6. Test Brake Function

Pump the brake pedal several times to ensure proper engagement of the brake pads.
Perform a test drive to verify that the squeaking noise has been resolved.
