Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is secure on jack stands before working under it.
•Allow brakes to cool before inspection or repairs to avoid burns.

Symptoms

•Vehicle shakes or vibrates during braking
•Pulsating sensation felt through the brake pedal
•Increased braking distance
•Possible squeaking or grinding noises from brake components
•Uneven wear on brake pads or rotors

Diagnostic Steps

1
Inspect the brake rotors for warping or damage by visually examining the surface.
2
Check the brake pads for even wear and ensure they are not worn down below the manufacturer’s specifications.
3
Verify the condition of the brake calipers to ensure they are functioning properly and not sticking.
4
Inspect the wheel assembly for loose or damaged components, including lug nuts and suspension parts.
5
Scan for any error codes using the Tesla service diagnostic tool to identify potential electronic issues.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Solution

1. Preparation

Gather tools and materials: brake pad and rotor replacement kit, socket set, torque wrench, brake cleaner, jack stands, and a jack.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts with a socket set while the vehicle is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping by measuring with a dial indicator or visually inspecting for grooves.
- If warped, remove the rotor by loosening the caliper bolts and sliding the caliper off.
- Replace the rotor with a new one, ensuring it is properly aligned.
Inspect Brake Pads:
- Remove the old brake pads by sliding them out from the caliper bracket.
- Compare the thickness of the old pads to the new ones; replace if they are below specifications.
- Apply brake grease to the backing of the new pads to prevent noise during operation.
Caliper Inspection:
- Check for proper operation of the caliper piston by pressing it in and ensuring it retracts smoothly.
- If the caliper is sticking, consider rebuilding or replacing it.

4. Reassemble Components

Reinstall the caliper over the new pads and rotor, tightening the caliper bolts to the manufacturer's torque specifications.
Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value using a torque wrench.

5. Final Checks

Pump the brake pedal to ensure proper brake function before driving.
Test drive the vehicle to confirm that the shaking during braking has been resolved.
