sounds like you may have air in the line..I ran into the same problom with manual brakes and the only way I got the air out was to jack up one end bleed it and then do the same to the other end ..

Like Pickel suggested you may have air in the entire brake system.Start by bleeding the master cylinder 1st.Do that the same way bleed the wheels. Have someone in the car pump up the brakes and then hold the pedal down while you loosen a brake line on the M/C.Do this to both the front and rear brake lines.When you start on each wheel we always let them "gravity" bleed 1st.Make sure the M/C is full of fluid and jack up either end of the car and open the bleeders on the wheels that are still on the ground.Let it sit like this for just a little bit then bleed each wheel.After you bleed the entire system you shouldn't need to bleed the M/C again.Try that and let us know what ya found out.
