I assume you used all the other existing gear ... so the leak could be in the banjos, the lines, or the master cylinder !
Remember that the seals on the piston will not want to move by themselves (especially not if they are new and nice and tight), so as you release the lever, there is suction on the _whole_ system, not just the seals.
Sorry, sounds to me as if you replaced the wrong bit.
