When brakes fail while driving, the recommended action is to downshift to a lower gear and apply the emergency brake. This method helps to gradually slow down the vehicle, leveraging engine braking from the lower gear to reduce speed. By downshifting, you engage the engine's resistance, which can assist in controlling the vehicle's speed. Simultaneously, utilizing the emergency brake provides an additional means to decelerate without abruptly stopping, which can be crucial in maintaining vehicle control. This approach is vital for safety, as it allows for a more controlled descent or stopping of the vehicle rather than a sudden halt, which could lead to loss of control or an accident. It’s important to be mindful of the condition of the emergency brake and to apply it smoothly to avoid skidding or losing traction.
