brake pressure

alright... so I was having an ABS problem. but that was solved when I replaced my hub assembly/sensor, so here's the issue, cause I"m honestly not sure, and was to get a shout on here before I get a diagnostics done at the dealer, so my brakes work.. but they loose pressure, and I have to push them down more and more as i'm stopping, and once I stop they still loose pressure op to about 2 inches from the bottom... it shouldn't be doing this.. even if I"m just backing out of the drive, to go to work, when I stop in reverse to put'er in drive, pedal still goes WAY down... however, I thought that it might be my master cylinder but, I don't completely lose pressure, I almost feel like theres air in the brake lines, but I bleeded them already, I guess I can try again, maybe I didn't get it out.. but I really feel like it's something else.. any ideas would be greatly appreciated, and thanks in advance.

-Josh

also, once i come to a stop, I let off the brake and quickly apply pressure again so that my pedal isn't bottomed out, cause I'll start moving again while trying to be stopped..

With constant foot pressure, does it stop sinking at some point before it reaches the floor?

Yes: Still air in the lines.
No, it sinks to the floor and then even after repumping, it keeps sinking: Leak.
