The handbrake, or parking brake is essential when it comes to keep a car stationary when idle or parked. Finding the handbrake has failed can be not only frustrating but if you’ve parked on a hill it could cause an accident. In this article we’ll investigate what causes handbrake failure and provide the key signs to recognise a failing parking brake.
1. Car isn’t stationary whilst handbrake is engaged
One sign of handbrake failure is when you engage the handbrake and the car continues to move along. This could be caused by wear over time, or a failure of the electronic system which controls the parking brake. Cars with a manual handbrake could also experience a ‘slack’ feeling to the handbrake, likely caused by a stretched cable.
2. Parking brake warning light appears
The clearest sign of handbrake failure is a flashing or constant ‘parking brake’ warning light being lit, even when the handbrake isn’t activated. Even attempting to engage the parking brake could provide a warning message indicating a fault with the brake system. However, sometimes warning lights can be faulty themselves, so it’s wise to check your manual. If you believe there is a fault then contact your local garage to help diagnose the issue. You could find that the cause is faulty electronics.
3. Slower acceleration than normal
Another telltale characteristic of a failed handbrake is a slower than normal acceleration of the vehicle. This could be caused by the parking brake being engaged constantly, providing increased friction to the wheels. Sometimes even your dashboard warning lights may not recognise this issue, as there could be an obstruction causing the sensors to miss this issue. Check the wheels when safe to see if there is anything obvious causing the issue.
