Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, caliper or ruler, flashlight, torque wrench.
Park the vehicle on a level surface and turn off the ignition.
Engage the parking brake and put on safety glasses and gloves.

2. Raise the Vehicle

Loosen the lug nuts on the front or rear wheel where brake pads are being checked.
Use the jack to lift the vehicle and securely place jack stands underneath.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect Brake Pads

Using the flashlight, visually inspect the brake pads.
Measure the thickness of the pads with the caliper. The minimum thickness should be at least 3 mm; replace if thinner.
Check the pad surface for cracks or uneven wear patterns.

4. Inspect Brake Rotors

Examine the rotors for any signs of scoring, rust, or warping.
If the rotor surface looks damaged, consider resurfacing or replacing it along with the pads.

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the jack.
Torque the lug nuts to the manufacturer’s specifications (typically around 100-110 ft-lbs for a Tesla Model 3).
Dispose of any waste materials properly if brake pads are replaced.
