crack the line from the frame mounted booster to the brakes and see if it has pressure on it. Then do the same to the line from the master to the booster. If ,aster to the booster has pressure the master cylinder is not releasing. If only the booster to brakes shows pressure then the vacuum booster is sticking and not releasing.
