Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Inspect Brake Components

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect the brake pads for thickness; replace if worn below the manufacturer's specifications (typically 3mm).
3. Check the brake rotors for any signs of warping or uneven wear using a dial indicator. Replace if necessary.

3. Replace Brake Pads and Rotors (if needed)

Sub-steps:
1. If brake pads need replacement, remove the caliper bolts and slide out the caliper.
2. Replace old pads with new ones, ensuring they are properly aligned.
3. If rotors are warped, remove the rotor screws and replace with new rotors, ensuring to torque bolts to the manufacturer's specifications (typically around 85 ft-lbs for Tesla).
4. Reinstall the caliper and wheel.

4. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure all alignment angles are within manufacturer specifications.
3. Balance the wheels if necessary.
