If you experience brake failure while driving, downshifting and steering to a safe area is a critical action. This technique allows you to reduce your speed by using the engine to help slow the vehicle down. It not only provides a smoother deceleration but also helps maintain control of the vehicle, making it easier to maneuver towards a safe area, such as the side of the road or an open space away from traffic.

By downshifting, you are using the vehicle's transmission to assist in slowing down, which can prevent a complete loss of control often associated with sudden stops. It is also important to maintain awareness of your surroundings during this maneuver, allowing you to make quick decisions as needed.

Engaging the emergency brake can also be a part of your response, as it provides an additional means to slow down. However, using it too abruptly might lead to skidding or losing control. Therefore, the most effective immediate response is to downshift while steering carefully.
