breaks, vacuum, and holly....

O.k... she's running good. But I think I need a vacuum canister for it. Cm must be a bit more then she wanted ;)

Basicly. The car runs great, and stops good at first, but at the end of the stopping. The power breaks quit and all I have left are standard breaks. The Master is connected to the Intake. Would it be beter in the carb? or do I just need to buy the vacuum canister for the car?
