In a Dual Air System, if one of the two air systems loses pressure, the result is that either the front or the rear brakes will not be fully operational. This design allows for redundancy; if one system fails, the other system can still function to some degree.

When pressure is lost in one part of the Dual Air System, the brakes may still operate, but they will not have the full braking power that they would under normal circumstances. Depending on which system loses pressure, either the front or rear brakes may have reduced functionality, leading to an uneven braking scenario. This is critical for maintaining some level of braking capability, which enhances safety compared to a single air system where complete failure would result in total loss of braking power. Thus, the correct understanding of the scenario in a Dual Air System is that one set of brakes could become less effective, while the other remains functional to some extent.
