There are 3 tanks in all air brake systems. A wet tank that recieves air from the compressor.
That tank supplies the primary and secondary tanks. Each tank handles either the front or rear brakes.
Your air suspension is probably hooked to the tank that handles the front brakes because they use less air to work.
There is also going to be a protection valve in the air suspension supply. That will cut off the air to the suspension if the pressure drops below 70 PSI, saving the rest for stopping.
If the leak is large enough that the compressor can't keep up ( not likely with suspension plumbing ), once the air drops below 60 psi, alarms start going off, and at 45 PSI the rear brakes come on, stopping you where you in your tracks.
