Ensure the Tesla is parked on a level surface.
Turn off the vehicle and engage the parking brake.

2. Inspect Brake Components

Brake Pad Inspection
- Remove the wheel using a socket set.
- Visually inspect brake pads for thickness; replace if worn below manufacturer's specifications.
- Tools Required: Socket set, torque wrench.
Rotor Inspection
- Measure rotor thickness with a micrometer; check for warping using a dial gauge.
- If warped, replace rotors following manufacturer specifications for thickness.
- Tools Required: Micrometer, dial gauge.

3. Tire and Alignment Check

Tire Inspection
- Check tire pressure; inflate to recommended PSI.
- Inspect for uneven wear patterns; replace tires if necessary.
Wheel Alignment
- Adjust wheel alignment using a wheel alignment tool.
- Follow specifications provided by Tesla for camber, caster, and toe angles.
- Tools Required: Wheel alignment tool.

4. Reassemble and Test

Reinstall the wheels and torque to manufacturer's specifications.
Perform a test drive to ensure that vibrations during braking are resolved.
