⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow the brakes to cool before servicing.
•Disconnect the vehicle battery before working on electrical components if applicable.

Symptoms

•Vibration felt in the steering wheel when braking
•Pulsation in the brake pedal
•Uneven wear on brake pads or rotors
•Increased stopping distance
•Noise during braking (squeaking or grinding)

Diagnostic Steps

1
Inspect brake pads for uneven wear and thickness.
2
Check brake rotors for warping or scoring.
3
Examine brake calipers for proper operation and any sticking issues.
4
Assess tire conditions, including balance and alignment.
5
Scan for any error codes related to the braking system using an OBD-II scanner.
6
Test brake fluid level and condition.

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

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, caliper tool.
Raise the vehicle using a jack and support it securely with jack stands.
Remove the wheel using a lug wrench.

2. Inspect Brake Pads and Rotors

Sub-steps:
1. Remove the brake caliper by loosening the caliper bolts with the appropriate socket.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid stress on the brake line.
3. Inspect the brake pads for uneven wear; replace if thickness is less than 3mm.
4. Use a caliper gauge to measure rotor thickness and check for warping by running a straightedge across the rotor surface. Replace if warping exceeds manufacturer specifications (typically 0.002 inches).

3. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. If pads or rotors are worn, remove old pads and rotor.
2. Clean the caliper bracket and apply anti-squeal grease to the contact points.
3. Install new rotors, ensuring they are properly aligned.
4. Place new brake pads in the caliper bracket and reattach the caliper, tightening bolts to the manufacturer’s torque specification.

4. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle to the ground.
3. Torque lug nuts to the manufacturer’s specifications (usually around 100-110 ft-lbs for Tesla Model 3).
4. Pump the brake pedal to seat the pads against the rotors before driving.
