If air pressure is not built up in time, what may occur?

The vehicle will accelerate uncontrollably
Brakes will become overly sensitive
Air pressure may drop to a low point, requiring an emergency stop
The safety valve will engage

The correct answer is: Air pressure may drop to a low point, requiring an emergency stop

When air pressure is not built up in time in an air brake system, it can lead to a drop in pressure that compromises the braking system’s effectiveness. In this scenario, if the air pressure falls to a low point, the brakes may not engage properly, which can necessitate an emergency stop to prevent an accident or loss of control of the vehicle. The air brake system relies on adequate pressure to function effectively; insufficient pressure can mean that you won’t have the required stopping power. Therefore, managing air pressure is crucial for safe vehicle operation, making the need for an emergency stop a significant concern when pressure is not adequately built up.
