...first question is how old is your air dryer??
Brett mine goes from 110-130. Not as much braking at 95. I do not need the retarder much at the higher air pressure
sitting at idle here in yard the back gauge reads 128 and the front 105 but no cyclingguess I need to replace the purge valve
Doug the "cans" on the wheels receive the chassis air. I think the system has metered flows. Being fed from a higher pressure reservoir made a noticable increase in my same pedal efforts...
OK anybody have a part number for a d2 govenor had this problem on my other coach
