Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface.
Disconnect the 12V battery for safety.
Tools Required: Jack, jack stands, wheel chocks, torque wrench, dial indicator.

2. Remove the Wheels

Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to raise the vehicle and secure it with jack stands.
Remove the wheels completely.

3. Inspect and Replace Brake Rotors (if needed)

Sub-steps:
- Use a dial indicator to measure rotor runout; anything over 0.002 inches indicates warping.
- If warped, remove caliper bolts and slide the caliper off the rotor.
- Remove the rotor by unscrewing any retaining screws if present.
- Replace with new rotors that meet OEM specifications.
Safety Warnings: Always use jack stands; do not rely solely on a jack.

4. Inspect and Replace Brake Pads (if needed)

Sub-steps:
- Remove the caliper from the rotor by unbolting it.
- Slide out old brake pads and inspect them for wear.
- Install new brake pads, ensuring they are oriented correctly.
- Reinstall the caliper over the new pads and torque the bolts to manufacturer specifications.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Torque the lug nuts to the specified value (typically 100-110 lb-ft for Tesla).
