my Tesla Outback's brake warning light is on, what should I do?

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
• Wear safety gloves and goggles.

2. Check Brake Fluid Level

• Sub-steps:
  • Open the hood and locate the brake fluid reservoir.
  • Inspect the fluid level; if low, top it off with the manufacturer-recommended brake fluid type (usually DOT 3 or DOT 4).

3. Inspect Brake Components

• Sub-steps:
  • Remove the wheel to access the brake assembly.
  • Check the brake pads for thickness; replace if less than 3mm.
  • Inspect the brake rotors for scoring or warping; replace if necessary.

4. Examine Brake Lines

• Sub-steps:
  • Visually inspect all brake lines for any signs of wear, corrosion, or leaks.
  • If damage is found, replace the affected brake line using appropriate fittings.

5. Replace Brake Pads and Rotors (if needed)

• Sub-steps:
  • Remove caliper bolts and slide the caliper off the rotor.
  • Replace old brake pads with new ones, ensuring they are properly seated.
  • If rotors are worn, remove the rotor and install a new one, torquing bolts to manufacturer specifications.

6. Reset Brake Warning Light

• Sub-steps:
  • Use the OBD-II scanner to clear any error codes related to the brake system.
  • Conduct a test drive to ensure the warning light does not reappear.

Tools Required:

• OBD-II scanner
• Socket set
• Torque wrench
• Brake fluid
• Brake pads and rotors (if replacement is necessary)
• Jack and jack stands

Parts Required:

• Brake fluid (DOT 3 or DOT 4)
• Brake pads (if worn)
• Brake rotors (if damaged)

Estimated Repair Time: 2-4 hours

Safety Warnings:

• Always disconnect the battery before working on electrical systems.
• Ensure vehicle is securely lifted and supported on jack stands before working under it.
