If your brakes fail while driving, using the emergency brake to stop the vehicle is a crucial and effective response. The emergency brake, also known as the parking brake, is designed to stop the vehicle when the primary brakes are not functioning. It operates independently of the primary braking system, allowing you to slow down the vehicle gradually.

When activating the emergency brake, it’s important to do so smoothly to avoid locking the rear wheels, which could lead to a loss of control. This method provides the best chance of safely bringing the vehicle to a stop without causing further hazards on the road.

Taking actions like panicking or making sudden moves can exacerbate the situation and lead to accidents or collisions. Coasting to a stop might not be practical depending on the circumstances, as it could allow the vehicle to gain speed or become less manageable. Continuing to drive without attempting to stop puts both the driver and others on the road at risk.
