What is an appropriate action if your brakes fail?

When brakes fail, the most appropriate action is to downshift to lower gears and use the emergency brake. This method helps slow down the vehicle gradually and allows for better control while managing the situation. Downshifting to lower gears utilizes engine braking, which adds a level of resistance as the vehicle's speed decreases. Simultaneously, engaging the emergency brake can further aid in deceleration without causing a sudden stop that could lead to loss of control.

Turning off the ignition can be dangerous as it may disable the steering and brake systems, leaving the driver unable to control the vehicle effectively. Pushing the brake pedal harder is unlikely to help since the brakes have already failed, and trying to force them may result in unnecessary wear or complete failure. Letting go of the steering wheel is counterproductive and would lead to a total loss of vehicle control, increasing the risk of collision or accident.
