If your brakes fail while driving, which of the following must be done FIRST?

In the event of brake failure while driving, the first action to take is to pump the brakes several times. This technique can often help build up brake pressure in the system, especially if the brake failure is due to air in the brake lines or if there is a temporary loss of fluid pressure. By pumping the brakes, a driver may be able to regain some braking function, allowing for better control of the vehicle and possibly bringing it to a stop.

Pumping the brakes is a critical first step because it may provide the driver with a chance to reduce speed or stop safely before moving on to other emergency responses. It's important to remember that this approach should be the initial reaction, as it can be effective for certain scenarios of brake failure.

The subsequent actions, such as shifting into neutral or applying the parking brake, may be necessary later on, but if the brakes can be engaged even slightly by pumping, the situation can potentially be managed more effectively. Steering towards a safe area is also a prudent action, but it should be a response to the brake situation after attempting to regain control.
