2012 Cascadia owners

How often does your air compressor cycle? 2012 cascadia uses air pressure for the def pump. Mine cycles Every 4-6min which I think is too often. Curious to see what others do?

Brake chamber would leak as soon as I released the brakes. My leaks only when moving. I really think that my def pump is using too much air

Well, then, replace the DEF pump.

When that doesn't work, look at the governor and brake system.
