When faced with brake failure, the recommended action is to pump the brakes to build pressure and then gradually use the parking brake. This method can help restore some level of braking capability by allowing the driver to attempt to slow the vehicle while maintaining control. Pumping the brakes may help create pressure in the brake system if it has simply lost hydraulic pressure. If the brakes fail completely, gradually applying the parking brake can bring the vehicle to a stop while minimizing the risk of skidding or losing control.

In contrast, attempting to accelerate or turning off the engine could lead to a loss of control and serious consequences. Steering sharply to the side of the road may create an additional risk of causing an accident, as it could lead to losing traction or colliding with roadside objects or vehicles. Thus, option B provides a clear, controlled approach to managing a brake failure situation.
