Diagnostic Steps

1
Inspect brake calipers visually for signs of rust or physical damage.
2
Check brake fluid levels and condition in the master cylinder.
3
Use a multimeter to test the caliper's electrical connections if it is electronically controlled.
4
Measure the temperature of the brake components using an infrared thermometer after a test drive.
5
Remove the wheel and inspect brake pads and rotors for wear patterns.
6
Check for proper movement of the caliper piston by manually retracting it.

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, socket set, caliper tool, torque wrench, multimeter (if needed).
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery to avoid any electrical issues during repair.

2. Remove Wheel

Loosen the lug nuts using a lug wrench.
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Clean Caliper

Spray brake cleaner on the caliper to remove dirt and debris.
Inspect the caliper for any signs of leaking brake fluid or physical damage.
Check the caliper slide pins for corrosion or dirt; clean them with a wire brush if necessary.

4. Remove and Repair Caliper

Using a socket set, remove the caliper mounting bolts.
Carefully slide the caliper off the rotor.
If the piston is stuck, use a caliper tool to gently retract the piston. If it does not move, it may need replacing.
Inspect the rubber seals around the piston; replace if damaged.

5. Reassemble Components

If the caliper is functioning correctly, apply high-temperature brake grease to the caliper slide pins and reinstall the caliper.
Torque the caliper bolts to the manufacturer's specifications (typically around 20-30 ft-lbs, verify with specific Tesla guidelines).
Reinstall the wheel and torque the lug nuts in a crisscross pattern to the recommended specifications (usually 80-100 ft-lbs).

6. Final Checks

Reconnect the battery and check for any error codes.
Perform a test drive to ensure the brakes are functioning properly without sticking.
