What should a driver do if they experience brake failure while going downhill?

When a driver encounters brake failure while descending a hill, safety is the foremost concern. The best course of action is to utilize the escape ramp or reduce speed using engine braking. Escape ramps are designed specifically for emergencies like brake failure, providing a safe area for vehicles to come to a stop without the risk of a serious accident. By using engine braking, the driver can effectively slow the vehicle down by downshifting and allowing the engine to help control the speed, reducing dependence on the brakes which are compromised.

This method is not only effective but also helps to maintain control of the vehicle, allowing the driver more time to react and make decisions in a potentially dangerous situation. Shifting into a lower gear helps to increase the engine's resistance and further aids in slowing the vehicle safely.

In contrast, attempting to drive faster to regain control only exacerbates the risk, as increased speed makes stopping or maneuvering more difficult and can lead to loss of control. Pumping the brakes may not be effective if the brakes have completely failed. Contacting roadside assistance is important, but it is secondary to immediately addressing the brake failure and ensuring safety through effective maneuvering.
