why does my Tesla Outback’s brake warning light keep coming on

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery to ensure safety while working with the braking system.

2. Check Brake Fluid

• Locate the brake fluid reservoir under the hood.
• Remove the cap and check the fluid level; add the appropriate brake fluid (DOT 3 or DOT 4) if low.
• Inspect the fluid for contaminants; if dirty, consider a brake fluid flush.

3. Inspect and Replace Brake Pads

• Remove the wheel using a lug wrench.
• Inspect the brake pads for thickness; if less than 3mm, replace them.
• Remove the caliper bolts with a socket set and carefully lift the caliper off the rotor.
• Remove old brake pads and install new ones, ensuring they are oriented correctly.
• Reinstall the caliper and torque the bolts to the manufacturer’s specifications.

4. Check Brake Rotors

• Inspect the rotors for scoring or warping.
• If rotors are damaged or worn beyond specifications, replace them.
• If they are still within specifications, consider resurfacing them if necessary.

5. Reassemble and Test

• Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.
• Reconnect the battery.
• Start the vehicle and pump the brakes to restore brake pressure.
• Test drive the vehicle to verify the brake warning light is no longer illuminated and braking performance is normal.
