The brake system warning light is one of the most important warning lights on your dashboard. It can illuminate for a variety of reasons, ranging from a simple reminder to engage the parking brake to a serious issue with your braking system. Understanding what the brake system warning light means can help you address the problem promptly and safely.
Common Reasons Why Your Brake System Warning Light is On
There are several reasons why your brake system warning light might be on. Some of the most common causes include:
- Parking brake is engaged: This is the most common reason for the brake system warning light to come on. Always double-check your parking brake before driving.
- Low brake fluid level: Brake fluid is essential for your brakes to function properly. A leak in the brake lines or worn brake pads can cause the fluid level to drop, triggering the warning light.
- Worn brake pads: Your brake pads have wear indicators that make a noise when they are getting thin. If you ignore this noise, the brake system warning light may illuminate.
- ABS issue: If there’s a problem with your Anti-lock Braking System (ABS), the warning light dedicated to ABS might turn on, often accompanied by the general brake system warning light.
- Brake system malfunction: A faulty brake caliper, brake hose, or master cylinder can also trigger the warning light.
