A car’s dashboard brake warning light can be found on the instrument panel and usually indicates that there’s an issue related to the car’s braking system. As a means of quick diagnostics, a brake light warning will tell you where the problem is, however, it doesn’t tell you exactly what the problem is. So, how do you fix the problem if the brake system warning light appears?

How Do You Fix a Brake Light Warning?

If your brake light is on, the problem can range from a mild wiring problem to a more serious brake-related issue that needs immediate attention. Here’s how to diagnose the most common causes of brake light warnings.

Pull Over Safely

Most of the tests for brake light warnings can’t (and shouldn’t) be conducted when you’re on the road. If you suspect that there’s an issue with your brakes, the first thing to do is to carefully press the brake pedal to test the brakes. If the brakes have cut out completely, steer the car to safety as best you can or engage the emergency brake once the car has slowed down enough.

Pull over safely before attempting to test anything else.

Restart the Vehicle and/or Dashboard

Sometimes the problem isn’t with the brakes. Instead, the ABS warning light on the dashboard may indicate that the instrument panel itself needs a reset. For this, the car should be switched off and restarted. This will allow the dashboard a moment to go back to normal. If the brake system light is still on warning you of an issue, move to the next step in diagnosing the problem.

Replace the Brake Pads

Brake pads are the component bringing the car to a standstill. Worn brake pads are one of the first reasons that a brake light might go on. Replacing the brake pads should be done every 10,000 to 20,000 miles. If you notice that braking the car has become tougher, have your brake pads replaced immediately.

Check the Brake Fluid

Brake fluid being empty (or close to it) is a common reason for a brake warning light to appear. Check your brake fluid periodically to ensure it is full. Remember to check the cable that takes brake fluid to the right place at the same time. Sometimes a hole or an obstruction can stop the travel of brake fluid, which poses a real danger on the road.

Check or Replace the Bulbs

If there’s no obvious issue with the brakes themselves, then check or replace the bulbs, as brake lights that are out can also cause the pane light to go on. Depending on the vehicle, if a brake light is out the brake warning light will appear due to the danger that it creates for you and other drivers on the road.

Check for a Blown Fuse

A blown fuse in the braking system can sometimes trigger the brake warning light. Modern vehicles rely on electrical components to manage brake functions, including the anti-lock braking system (ABS) and brake lights. Locate the fuse box (typically under the dashboard or hood) and check for any blown fuses related to the braking system. Replacing a faulty fuse may resolve the issue and turn off the warning light.

Stop the vehicle and check the Parking Brake

Wiring or physical issues with the parking brake can also be a reason for the indicator light to come on. Stop and check to see if the parking brake is engaged or if the parking brake light is on if no other obvious issue with the brakes of the car can be found. If needed, disengage the parking brake and check if the warning light turns off.

Monitor the ABS Light and Brake Pedal Feel

The ABS (Anti-lock Braking System) warning light, often displayed alongside the brake warning light, could indicate a malfunction in the ABS system. While the ABS doesn’t affect normal braking directly, it helps prevent wheel lockup during hard braking. If the ABS light comes on in conjunction with the brake system warning light, it’s crucial to have the ABS system inspected as soon as possible.

Additionally, pay attention to any changes in how the brake pedal feels when you apply pressure. If the pedal feels spongy or unusually firm, or if there is increased resistance, this could be a sign of an underlying issue such as air in the brake lines, worn brake components, or a hydraulic failure.

Take Your Car to an Auto Shop

Depending on your experience level, there are some vehicle-related issues that can be fixed at home, and there are others that require professional attention. If you can’t figure out why your brake light warning signal is on, visit to a professional auto shop near you to diagnose and fix the issue.

A brake system failure is a serious matter, and ensuring that all safety features are functioning correctly is crucial before you drive the car again.
