Solution

1. Preparation

Tools Required: Socket set, torque wrench, flathead screwdriver, brake pad spreader tool, jack and jack stands.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the 12V battery to disable the electrical systems.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads you are replacing.
Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brake assembly.

4. Remove the Brake Caliper

Locate the caliper bolts and use a socket to remove them.
Carefully slide the caliper off the rotor and suspend it using a bungee cord or rope to avoid straining the brake line.

5. Replace the Brake Pads

Remove the old brake pads from the caliper bracket.
Use a brake pad spreader tool to compress the caliper piston back into the caliper to accommodate the new pads.
Install the new brake pads into the caliper bracket, ensuring they are seated securely.

6. Reinstall the Brake Caliper

Slide the caliper back over the new brake pads and rotor.
Reinstall and torque the caliper bolts to the manufacturer’s specifications (typically 25-30 ft-lbs for Tesla).

7. Reattach the Wheel

Place the wheel back on the hub and hand-tighten the lug nuts in a star pattern.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (typically 129-145 ft-lbs for Tesla).

8. Reconnect the Battery

Reconnect the 12V battery and ensure all electrical systems are functioning properly.
