When will it stop? Brake question

If your booster tests out okay, adjust the rod coming out from the booster out further (lengthen it) even if you don't see any slack. Try like a 1/4" and see if you get some assist. then another 1/4" if that didn't change pedal feel. I had to lengthen mine to get power assist feel and it took a few times. I could, however, feel a positive change as soon as I lengthened it. Perhaps vacuum it pulls back in somewhat when the engine is running? In any event, it worked for me and at this point you don't have anything to lose by trying it before you start throwing money into a new booster.
