What should you do if you experience hydraulic brake failure?

Answer: C — Pump the brake pedal

If you experience hydraulic brake failure, one of the immediate actions you should take is to pump the brake pedal. This technique can help build up some hydraulic pressure in the brake system, which might allow you to regain partial braking control. In many cases, this action can activate the braking system enough to slow down the vehicle, giving you a better chance of coming to a safe stop. When hydraulic brake failure occurs, the brake pedal may go to the floor without slowing the vehicle effectively. Pumping the brake pedal can create a temporary increase in pressure that sometimes allows the brakes to function, enabling you to reduce your speed. It's important to remain calm and handle the situation safely. While activating hazard lights or using the handbrake can also be part of a broader response for safety, pumping the brake pedal directly addresses the issue of losing braking ability and can provide a crucial moment to manage the situation effectively.
