When faced with brake failure while driving, the appropriate action is to shift to a lower gear and use the emergency brake. This method utilizes the vehicle’s engine resistance to slow down gradually, providing better control and preventing a sudden stop that could lead to a collision or loss of control. Engaging the emergency brake can further assist in bringing the vehicle to a halt, especially if done smoothly to avoid skidding.

In contrast, panicking and pulling the parking brake compromises your ability to make sound decisions and risks an abrupt stop, which could result in an accident. Simply accelerating to find a safe spot is dangerous, as this does not address the immediate problem of losing braking ability. Finally, turning on hazard lights is helpful for alerting other drivers, but it does not effectively address the need to stop your vehicle safely. Thus, utilizing both the lower gear and emergency brake represents a strategic approach to managing brake failure.
