Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pad condition for wear and proper installation.
3
Examine brake calipers for proper function and alignment.
4
Inspect the wheel assembly and suspension components for loose or damaged parts.
5
Perform a test drive to confirm braking behavior under different conditions.

Solution

1. Preparation

Tools Required: Wheel lug wrench, jack, jack stands, dial indicator, torque wrench.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and place it securely on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

A. Brake Rotor Inspection

Use a dial indicator to measure rotor runout. If the runout exceeds specifications (usually 0.002-0.005 inches), the rotor may be warped.
If warped, proceed to replace the rotor.

B. Brake Pad Inspection

Inspect for uneven wear or damage. Replace pads if necessary.

4. Replace Brake Rotor (if required)

Remove caliper bolts and slide the caliper off the rotor.
Remove the rotor from the hub.
Install the new rotor, ensuring it sits flush against the hub.
Reinstall the caliper and torque bolts to manufacturer's specifications (typically around 79-89 lb-ft for Tesla).

5. Reinstall Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts, then lower the vehicle from the jack stands.
Torque lug nuts to manufacturer's specifications (around 129 lb-ft for Tesla).

6. Final Inspection

Double-check all fasteners and components for secure installation.
Reinstall the wheel and perform a test drive to confirm repair effectiveness.
