Problem Statement

Learn how to diagnose and fix shaking when braking in Tesla Model 3 Highland. Step-by-step guide with diagnostic procedures and repair instructions.

Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Allow the vehicle to cool down before working on brake components.

Symptoms

•Steering wheel shakes during braking
•Vehicle vibrations felt through the floor or seats
•Increased stopping distance
•Brake pedal pulsation
•Noise from the brakes (squeaking or grinding)

Diagnostic Steps

1
Inspect brake components visually for wear or damage, including rotors, pads, and calipers.
2
Check brake rotor thickness using a micrometer to ensure they are within specifications.
3
Examine suspension components (control arms, bushings, struts) for wear or damage.
4
Perform a road test to observe the conditions under which the shaking occurs (speed, braking intensity).
5
Scan the vehicle’s onboard computer for any error codes related to the braking system.

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

Tools & Equipment Required

•Lug wrench
•Jack and jack stands
•Socket set
•Torque wrench
•Micrometer (for rotor measurement)
•OBD-II scanner (for code reading)

Parts Required

•Brake rotors (if warped or worn)
•Brake pads (if worn)

Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the vehicle from power if necessary.

2. Remove Front Brake Wheels

Loosen the lug nuts on the front wheels using a lug wrench.
Raise the vehicle with a jack and secure it on jack stands.
Completely remove the front wheels.

3. Inspect and Replace Brake Rotors and Pads

Remove the brake caliper by unbolting it from the mounting bracket.
- Tools required: Socket set, torque wrench.
Carefully hang the caliper using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Measure the brake rotors for thickness and inspect for warping.
- If the rotors are worn beyond specifications or warped, replace them.
Install new brake pads into the caliper bracket.
Install new brake rotors (if applicable) and ensure they are properly seated.

4. Reassemble Brake Components

Reattach the brake caliper to the mounting bracket, tightening to manufacturer specifications.
Reinstall the front wheels and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the specified value.

5. Test Drive

Conduct a test drive to ensure that the shaking during braking has been resolved.
Monitor the vehicle for any additional sounds or vibrations.
