Solution

1. Preparation

Gather necessary tools and safety equipment.
Tools Required:
- Jack and jack stands
- Lug wrench
- Caliper or measuring tool
- Safety goggles
- Gloves

2. Lift the Vehicle

Use the jack to lift the front or rear of the Tesla Model S Plaid, depending on which brakes you are inspecting.
Place jack stands under the vehicle to securely support it.

3. Remove Wheel

Using the lug wrench, loosen and remove the lug nuts on the wheel.
Carefully take off the wheel and set it aside in a safe location.

4. Inspect Brake Pads

Visually inspect the brake pads for wear, looking for cracks, uneven wear, or significant thinning.
If visible, check the wear indicator tabs; replace pads if they are worn down to the indicator.

5. Measure Pad Thickness

Using a caliper, measure the thickness of the brake pads.
Compare the measurement to the manufacturer's specifications (typically, pads should be replaced when they reach around 3mm thickness).

6. Reassemble

Reattach the wheel and tighten lug nuts to the manufacturer's torque specifications.
Lower the vehicle back to the ground.
