how to tell if my Tesla Model 3 Highland (2024-present) calipers are causing uneven brake wear

Solution

1. Preparation

• Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, caliper tool, multimeter, inspection mirror.
• Safely park the vehicle on a flat surface and engage the parking brake.
• Disconnect the battery to prevent any electrical issues during the process.

2. Raise the Vehicle

• Use a jack to lift the vehicle at the designated lift points.
• Securely place jack stands under the vehicle for safety.
• Remove the wheel using a lug wrench.

3. Inspect the Calipers

• Visually inspect the calipers for signs of sticking or damage.
• Use an inspection mirror to check the piston movement; it should extend and retract smoothly.
• Clean any dirt or debris on the calipers using brake cleaner.

4. Examine Brake Pads

• Measure the thickness of each brake pad using a caliper tool.
• Identify any uneven wear patterns. Replace any pads that are worn beyond manufacturer specifications.
• If the pads are uneven, check the caliper movement.

5. Check Rotor Condition

• Measure the rotor thickness using a micrometer.
• Inspect for warping or scoring. Replace rotors that are below the minimum thickness or have significant damage.

6. Reassemble and Torque

• Reinstall the calipers and ensure they are properly aligned.
• Use a torque wrench to tighten bolts to manufacturer's specifications.
• Reattach the wheel and lower the vehicle.
