What Can Cause Your Brake Warning Light to Turn On?

Your car's brakes are some of the essential safety features that need to be fully functional at all times. As such, you need to take a brake warning light on your dashboard very seriously. In most cases, a brake warning light may mean replacing the brakes. However, sometimes it may indicate a leaking brake fluid, which is an emergency that needs immediate attention.

Most modern vehicles have three types of brake warning lights; one that indicates a problem with the anti-lock braking system (ABS), one that shows the parking brake is engaged, and finally one for the brakes themselves, which is the most serious one. Below are 3 of the reasons why your brake warning light may turn on.

Low/Leaking Brake Fluid

The brakes need enough brake fluid to operate well. When the brake fluid drops below the required level, a sensor in the master cylinder triggers the brake light on the dashboard to turn on. If your brake fluid has been leaking for a while, the brake fluid reservoir will be nearly empty. A low brake fluid level could also be a sign of worn-out brake pads. Ensure you take your vehicle to a reputable service center for inspection to help determine where the fluid is leaking from. A leaking brake fluid is a serious safety hazard.

A Malfunctioning Speed Sensor

A speed sensor reads the speed at which your car tires rotate and relays the information to the ABC control module. A faulty speed sensor will cause the ABS lights to come on and the anti-locking braking system to fail. As such, you may not be able to drive your car safely.

Worn-Out Brake Pads

When you step on the brake pedal, the brake pads press the disc rotors, causing friction to slow down your car. A problem with the brake pad will cause the brake warning lights to illuminate. If you suspect a problem with your brake pads, take your vehicle to a mechanic to replace them for you before your brakes stop working altogether.
