A parking brake is an essential automotive feature used when the main brakes fail. It can also keep your car stationary, especially when parked on a steep incline. However, just like any car mechanism, parking brakes can malfunction. A stuck parking brake is a frustrating issue, but understanding how this essential component works can help you perform some basic troubleshooting.

How Parking Brakes Work

A parking brake is a system of cables that connects the rear wheel brakes to a lever operated by hand. It’s also called the emergency brake, e-brake, or handbrake. The parking brake prevents a car from rolling forward or backward when the vehicle is not in motion. Applying the brake involves holding the hand grip, pressing the button at the end of the grip, and raising the lever. Releasing the parking brake entails slightly raising the grip, pressing the button, and then lowering it forward.

What Causes a Stuck Parking Brake

If you find yourself with a stuck parking brake, correctly diagnosing the cause of the problem may allow you to resolve it on your own.

Freezing

Cold weather can freeze brake cables in place. If this is the problem, try turning on the engine and letting the car warm up for a few minutes to melt the ice on the cables. You can then try releasing the handbrake several times to break up the remaining ice.

Corrosion

Another possible reason for a stuck parking brake is corrosion or rusting of the cable. In this instance, you could try getting it unstuck by applying and releasing the brake several times. You could also try slightly rocking the car back and forth a few times. Both methods might help dislodge some of the rust buildup. However, you should have an auto repair professional examine your brake to ensure that the component is in good condition.

Harsh Pulling

A handbrake can get stuck is if it’s pulled too high or with too much force. This could cause the brakes to get jammed against the walls of the wheel. Try gently releasing the handbrake several times. If this doesn’t work, it’s best to seek help from an auto professional to avoid further damage to the car.
