brake booster

I have a 57,3100 chev pickup with a CPP firewall mount P/B kit. After two different boosters, from them,problem still remains. Brake pedal will not return last 1/4"-1/2" or so. Brakes bind. With vacuum disconnected,driving vehicle, brake pedal returns completely and firmly. Everything is new,no binding anywhere, pedal has return spring,etc. Booster pin is adjusted with a gauge. All the usual areas to check/confirm have been done. Brake system works great otherwise. I am convinced it's a cheap overseas booster that's the problem. CPP believes otherwise. I get, "there's nothing about a booster that could cause this". Well, then why does the pedal return VERY good with out vacuum applied, while idling/driving vehicle? Am I missing something here?

Talked to a booster rebuild shop, and they said definitely a booster issue.Maybe they said that in order to sell me a booster, but I'll give them the benefit of the doubt for now. Any thoughts?

Was looking at MBM brake boosters. USA made? Got to get this bullcrap resolved.
