⚠️ Safety Warnings

Important safety information - read before proceeding

•Always engage the parking brake and use jack stands when working under a vehicle.
•Allow the brakes to cool before inspection to avoid burns.

Symptoms

•Squeaking or squealing noise when braking
•Vibrations or pulsations when applying brakes
•Decreased braking performance
•Warning light for brake system on the dashboard
•Brake pads visibly worn down

Diagnostic Steps

1
Lift the vehicle using a jack and secure it with jack stands; remove the wheel to access the brake assembly.
2
Measure the thickness of the brake pads using a caliper; compare to manufacturer specifications for minimum thickness.
3
Look for any cracks, chips, or unusual wear patterns on the brake pads.
4
Inspect the rotors for grooves, scoring, or warping, which can affect pad performance.
5
Check around the brake calipers and brake lines for signs of brake fluid leaks.

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

Solution

1. Preparation

Gather tools: lug wrench, jack and jack stands, caliper gauge, flashlight, and cleaning cloth.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts slightly before lifting the vehicle.
Use the jack to lift the vehicle and place jack stands underneath for safety.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Pads

Visibility: Use a flashlight to illuminate the brake assembly.
Thickness Measurement: Use a caliper to measure the thickness of the brake pads, ensuring they are above the manufacturer's minimum threshold (typically around 3mm).
Visual Condition: Examine the pads for any signs of cracking or uneven wear.

4. Inspect Brake Rotors

Assess the surface of the brake rotors for any signs of wear, scoring, or warping.
If necessary, use a rotor gauge to measure rotor thickness and ensure it meets specifications.

5. Clean and Reassemble

Wipe any dust or debris from the brake components using a clean cloth.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque (usually 80-100 ft-lbs for Model 3).
