What is the first step in handling brake failure?

The first step in handling brake failure is to activate the parking brake or turn off the engine. In a situation where the brakes fail, it is crucial to slow down the vehicle as quickly and safely as possible to prevent a potential accident. Engaging the parking brake allows the driver to decelerate the vehicle progressively. This action provides an alternative means of slowing down, especially if the regular brakes are unresponsive.

Turning off the engine can help reduce the speed of the vehicle, though it should be done with caution since it removes power steering and power braking, making the vehicle harder to control. Nonetheless, reducing speed and coasting to a stop is essential, and activating the parking brake is the most immediate and effective first measure a driver can take in this emergency situation.

Other steps, such as shifting to different gears or activating the horn, may be appropriate later in the process or for signaling to others on the road, but they do not directly address the immediate need to reduce speed and control the vehicle in the event of brake failure.
