What is the Parking Brake Light?
The parking brake light, also known as the brake warning light, is a critical safety feature in your vehicle. It’s designed to alert you when there’s a problem with your parking brake or brake system. The light is usually located on your dashboard and is typically yellow or amber in color. When the light is on, it’s a sign that there’s an issue that needs to be addressed.
Why Does My Parking Brake Light Stay On?
There are several reasons why your parking brake light might be staying on. Here are some of the most common causes:
1. Parking Brake Not Fully Released
One of the most common reasons for a parking brake light to stay on is that the parking brake hasn’t been fully released. This can happen if you’ve parked your car on an incline and the parking brake is still engaged. To fix this issue, simply pull the parking brake lever all the way back to release the brake.
2. Faulty Parking Brake Sensor
Another common cause of a parking brake light staying on is a faulty parking brake sensor. This sensor is responsible for detecting whether the parking brake is engaged or not. If the sensor is faulty, it may trigger the parking brake light to stay on even when the brake is fully released. In this case, you may need to have the sensor replaced by a professional mechanic.
3. Brake Fluid Level Low
If your brake fluid level is low, it can cause the parking brake light to stay on. This is because the brake fluid level sensor is connected to the parking brake light. To fix this issue, you’ll need to have your brake fluid level checked and topped off if necessary.
4. Brake Pads Worn Out
Worn-out brake pads can also cause the parking brake light to stay on. This is because the brake pads are responsible for applying pressure to the brake rotors to slow down the vehicle. If the brake pads are worn out, it can cause the parking brake light to stay on. In this case, you’ll need to have your brake pads replaced by a professional mechanic.

5. Brake Master Cylinder Faulty
A faulty brake master cylinder can also cause the parking brake light to stay on. The brake master cylinder is responsible for distributing brake fluid to the brake calipers. If the master cylinder is faulty, it can cause the parking brake light to stay on. In this case, you’ll need to have the master cylinder replaced by a professional mechanic.
6. ABS Sensor Faulty
A faulty ABS sensor can also cause the parking brake light to stay on. The ABS sensor is responsible for detecting wheel speed and applying the brakes when necessary. If the sensor is faulty, it can cause the parking brake light to stay on. In this case, you’ll need to have the sensor replaced by a professional mechanic.
