What should a driver do if their foot brake fails?

If a driver experiences a failure of their foot brake, utilizing the parking brake is the most effective immediate response. The parking brake, also known as the emergency brake, is designed to hold the vehicle stationary when parked but can also be used to slow down or stop the vehicle in an emergency situation. Engaging the parking brake gradually will help to reduce the car's speed safely without causing the wheels to lock up or leading to loss of control.

It's important to apply the parking brake smoothly to prevent the vehicle from skidding. By doing so, the driver can avert a potentially dangerous situation and maintain better vehicle control. This action should be combined with efforts to steer the car to a safe area and signal to other drivers as needed.
