Brake fluid was at one time coming out, and then it stopped- I was using a vaccum bllder plus pushing the pedal. I did have a person pressing and holding the brake pedal it was not getting any better worse in fact - ( maybe it was sucking air in from my connection, then it just would not bleed out... I did take the bleed screw right out .. and no fluid was coming out ... I do believe i have a lot of air in the system.
