Car Won’t Start, Says “Check Brake System”
What This Means
When you see the message “Check Brake System” on your car’s dashboard, it means that the car’s computer has detected a problem with the brake system. This could be a minor problem, such as a low brake fluid level, or it could be a more serious problem, such as a faulty brake booster.
Regardless of the cause, it’s important to take this warning seriously and have your car checked out by a qualified mechanic as soon as possible.
What to Do
- Check your brake fluid level. The brake fluid reservoir is usually located under the hood, near the firewall. The fluid level should be between the “MIN” and “MAX” marks on the reservoir.
- Inspect your brake pads and rotors. The brake pads and rotors are located inside the wheels. You can inspect them by removing the wheels and looking for any signs of wear or damage.
- Have your brake system inspected by a mechanic. If you’re not comfortable checking your brake system yourself, or if you find any problems during your inspection, it’s important to have your car inspected by a qualified mechanic.
