If you experience brake failure while driving, shifting to a lower gear and trying to slow down is a critical action to take because it utilizes the vehicle's engine to assist in reducing speed. By downshifting, the engine helps create resistance that can gradually slow the vehicle down, providing you more control while you assess the situation. This technique, called engine braking, can be especially effective in large vehicles or trucks.

It's also important to note that turning off the engine immediately can lead to a loss of steering and other systems, making it more difficult to control the vehicle. Calling for help while driving would divert your attention away from the necessary immediate actions to maintain control and manage the vehicle safely. Continuously pumping the brakes may be effective in some situations, but if the brake system has failed completely, it might not provide any stopping power and could waste valuable time. Thus, downshifting to lower gears offers a practical way to enhance control and safety in an emergency scenario like brake failure.
