What should be done if the air pressure drops rapidly?

If the air pressure drops rapidly, it is critical to immediately pull over and inspect for a leak. The air brake system relies on a specific level of air pressure to function effectively. A rapid drop in air pressure indicates a potential malfunction, such as a leak in the air lines or a failure in the compressor. This situation poses a significant safety risk, as inadequate pressure can lead to brake failure, thereby compromising the safety of the driver, passengers, and other road users.

Pulling over allows for a thorough inspection of the system to identify any issues that need addressing before continuing to drive. Ensuring that the air brake system is in proper working order is essential for safe operation, especially when navigating heavy vehicles that rely on air brakes for effective stopping power. Consequently, taking prompt action to investigate and resolve any pressure loss is vital for maintaining safety on the road.
