Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, infrared thermometer, torque wrench.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the negative terminal of the battery as a safety precaution.

2. Lift the Vehicle

Use the jack to lift the front or rear of the Tesla, depending on which calipers you are inspecting.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts from the wheel.
Take off the wheel to expose the brake caliper.

4. Inspect Calipers

Visually inspect the caliper for any signs of damage or corrosion.
Check the caliper piston for proper movement; it should retract smoothly when pressed.
If the caliper appears stuck, proceed to remove it for further inspection.

5. Remove Caliper

Use the appropriate socket to remove the bolts securing the caliper to the bracket.
Carefully slide the caliper off the rotor, ensuring not to damage the brake line.
Support the caliper with a bungee cord or a suitable hanger to avoid stressing the brake line.

6. Inspect and Clean

Check the caliper slide pins for seizing; they should move freely.
Clean the caliper bracket and slide pin recesses with brake cleaner.
Apply brake grease to the slide pins and ensure they are lubricated for smooth operation.

7. Reassemble

Reinstall the caliper onto the rotor and secure it with the bolts. Use a torque wrench to tighten to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the recommended specifications.

8. Final Checks

Reconnect the negative terminal of the battery.
Pump the brake pedal to restore brake pressure before driving.
