Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system to avoid electrical shock.
•Allow the brake components to cool before handling after driving.

Symptoms

•Vibration felt through the steering wheel during braking
•Pulsating brake pedal feedback
•Uneven brake wear noticeable on inspection
•Increased stopping distance
•Possible noise (grinding or squeaking) when braking

Diagnostic Steps

1
Inspect brake pads for wear and condition.
2
Check brake rotors for warping or uneven surfaces using a runout gauge.
3
Examine wheel alignment and suspension components for damage or misalignment.
4
Scan for any fault codes related to the braking system using an OBD-II scanner.
5
Inspect tire condition and balance.

Solution

Solution

1. Preparation

Gather tools and safety gear.
Ensure the vehicle is on a flat surface and securely engage the parking brake.
Disconnect the vehicle's battery to prevent any electrical issues.

2. Inspect and Replace Brake Pads

Remove Wheel
- Use a socket set to remove the lug nuts and take off the wheel.
Inspect Brake Pads
- Check for uneven wear; replace if they are worn below the manufacturer's specifications.
Install New Brake Pads
- If replacement is necessary, install new brake pads ensuring they are properly seated.
- Torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 Nm).

3. Check and Replace Brake Rotors

Inspect Rotors
- Use a runout gauge to measure rotor thickness and warping; replace if necessary.
Remove Caliper
- Take off the caliper by removing caliper bolts with a socket set.
Replace Rotor
- Remove old rotor and install new rotor, ensuring it is secure.
- Torque the rotor retaining screws to the manufacturer's specifications (typically around 10-15 Nm).

4. Brake System Bleeding

Bleed the Brakes
- Reconnect the brake lines and bleed the brake system to remove any air bubbles.
- Use a brake bleeder kit or vacuum pump, following the specific process for the Tesla braking system.

5. Reassemble and Test

Reinstall Wheel
- Place the wheel back on and torque the lug nuts to the manufacturer’s specifications (typically around 110-130 Nm).
Reconnect Battery
- Reconnect the battery terminals and ensure all electrical systems are functioning.
Test Drive
- Conduct a test drive to ensure that the shaking during braking is resolved.
