My guess is you have a large bubble somewhere in one of the lines.

This is where a mity vac helps because you have to push large amounts of fluid through.

I don't have one, and simply kept doing it by hand. I also took off the calipers and hung them up for awhile... basically trying anything to get the air to move.

Many people had success with tying the lever closed and let the bubble work to the top.

Did you add a bleeder at the top, near the master cylinder? That sometimes helps get air out.
