What should you do if your brakes fail while driving?

When faced with brake failure while driving, the appropriate response is to pump the brakes, downshift to lower gears, and if needed, utilize the emergency brake. Pumping the brakes can sometimes build up brake fluid pressure, which may help slow the vehicle down if the issue is a minor brake failure.

Downshifting is crucial as it allows the engine to help slow the car, utilizing engine braking. This method provides an additional layer of deceleration before reaching a complete stop. Lastly, engaging the emergency brake gives you a backup method to stop the vehicle, though it should be used carefully to avoid skidding.

The other options do not provide safe or effective means to cope with brake failure. For instance, steering off the road could lead to losing control, while panicking and pressing the gas pedal would only exacerbate the situation, increasing speed and the likelihood of a collision. Putting the car in neutral might prevent further driving momentum, but it also removes engine braking benefits and could lead to loss of control. Thus, the correct approach combines multiple techniques ensuring the driver maintains control and safely brings the vehicle to a stop.
