When I start truck up in the morning air leaks from the air dryer causing air pressure not to raise past 30psi . I give a few taps with a 3lb hammer and the air leaks stops and pressure builds up and will work for the rest of the day occasionally I will have to tap dryer after I had been shut down wondering why it is happen how to fix maybe or should I just replace Mack told me the carry a smaller air dryer in place of the old long air dryer I currently have and said some plumbing or air hose might have to be done . Any ideas or suggestions ? Thanks for any responses Sent from my iPhone using Tapatalk

I have 84dm688sx I had a rebuild on trans done I broke the main shaft on trans I had the same problem after rebuild brought back and it was leaking air bolt was missing installed bolt and it worked after that properly . Every once in a while it won't go I flip lever a couple times it will pop in check for missing bolts. does your truck drop air pressure quickly ? Sent from my iPhone using Tapatalk
