Suspension dump

[Zondo956]

I’ve had suspension stay down on tractor when I start truck a couple times before. I just flip the suspension dump switch and airs up normally.
Today I started noticing a loud air leak when driving. Only happens when compressor fills air tanks to maximum(@130). Stops leaking when I press brake pedal.
Turns out it’s the solenoid that leaks.
Could it be that it’s just faulty or should I be worried it’s an electrical problem?
Also plan on changing out the leveling valve due to it leaking in cold weather. Could that cause the solenoid to act up?
Has anyone experienced similar situation
