BDifficulty 2/5

In a vehicle with hydraulic brakes, the pedal sinks to the floor without braking. Which of these actions may help recover pressure while you maintain control?

Correct answer

Pump the pedal to try to recover pressure while maintaining control.

You may try pumping the pedal to recover pressure, without a guarantee of success. Maintain control, release the accelerator, warn of danger and seek a safe stop according to the vehicle instructions. Do not jerk the parking brake or choose to strike any rigid object. This differs from emergency braking with functioning ABS, where the pedal is not pumped. Once stopped, do not continue with faulty brakes.
