Thanks for the input. I have been delayed in breaking this open due to family obligations..... I was moving it today to a better area to work and as I pressed the brake i heard a couple of little pops and now when I press the brake I can hear constant vacuum sucking at the vacuum vent in the cab and the engine roughs up so I'm gathering my diaphragm has been compromised........ On that note.... does anyone have a recommended booster parts supply house? My normal avenues have told me its obsolete. I would like to rebuild this unit myself to better understand the system. Thanks again for the collected knowledge of this forum.
