What should you do if your brakes fail while driving?

If your brakes fail while driving, shifting to a lower gear and pumping the brakes is the best response. This action helps to slow the vehicle down using engine braking, which can be effective when the brake system is not responding as it should. By downshifting, you take advantage of the engine's resistance, thereby reducing speed gradually. Additionally, pumping the brakes in case of a partial brake failure can sometimes build up pressure in the brake lines, potentially allowing for some brake function.

While other options may seem like they could assist in a brake failure situation, they are not the best initial steps to ensure safety. For instance, pulling the emergency brake immediately can cause skidding or loss of control if done abruptly. Turning off the engine would disable power steering and other vehicle functions, leading to greater difficulty in steering and control. Ignoring the situation is never advisable, as it could lead to dangerous consequences. Thus, shifting to a lower gear and pumping the brakes optimally addresses the immediate need for controlled deceleration.
