ok car is a crx w/ integra suspention

problem....cant seem to get enough pressure on the brakes

brand new booster and master from a crx si

car has been sitting for about two years now...im thinking the callipers froze on me.... ive bled the system about five times now, and the pedal has pressure when the car is off, but when you turn it on it seems to loose it.....the pedal wont go all the way to the floor, but its not far off car still stops, but i dont think i could lock up the brakes even if i tried..... any ideas cause im about out?
