What was your bleeding method?  May not have got all of the air.

The method that I use for bleeding brakes:
1. Start at the wheel farthest from the Master Cyl.
2. Pump the brakes until they are rock hard (If they dont get hard, just
pump 20~30 times.  After repeating several times, they will get harder.)
3. Hold the pedal to the floor.
4. Loosen the bleed valve only until the fluid stops gushing.  It should
be pretty foamy until you get the air out.  (Remember to put a tube over
the valve so that the fluid doesn't get everywhere)
5. Repeat 2~4 several times.
6. Move to the next closest wheel.
7. When all brakes are done, do 1~6  one more time.

It takes a while, but it's worth it to be able to stop.  If through the
process, you find that the brakes never get hard or pumped up, bleeding
probably isn't your problem.
