Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Torque wrench
- Brake cleaner
- Safety glasses
- Gloves
Safety Warnings:
- Ensure the vehicle is on a flat surface and securely supported by jack stands before working on the brakes.
- Wear safety glasses and gloves to protect from dust and debris.

2. Elevate the Vehicle

Loosen the lug nuts of the front or rear wheels (depending on which you are inspecting) slightly while the vehicle is still on the ground.
Use the jack to lift the vehicle and securely place it on jack stands.
Remove the wheel by fully unscrewing the lug nuts.

3. Inspect Brake Pads

Visually inspect the brake pads through the caliper. Use a flashlight if necessary to see the pad thickness.
If the pads are visibly worn down to or below 3mm, they need to be replaced.

4. Replace Brake Pads (if necessary)

Remove Caliper: Unscrew the caliper bolts and carefully lift the caliper off the rotor. Support the caliper with a bungee cord or similar to avoid stress on the brake line.
Remove Old Pads: Slide the old brake pads out from the caliper bracket.
Install New Pads: Insert new brake pads into the caliper bracket. Ensure they are oriented correctly and seated properly.
Reattach Caliper: Position the caliper back over the new pads and secure it by tightening the caliper bolts to the manufacturer’s torque specifications (usually around 20-25 ft-lbs for Tesla).

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and remove them.
Tighten the lug nuts to the manufacturer’s torque specifications (usually around 100-110 ft-lbs for Tesla).
