I'd say your sucking air from somewhere, if you pump up the brake pedal, does it go anything but to the floor? If it will not pump up after opening the blled valves with pressure on the brake pedal, I'd say look at all the wheel cylinders, if you have a leak there you will know it. Vaccum bleeders have been around a long time, but I still like the manul bleed with two guys and pumping the brake pedal.
