I just had the same problem with my camry.. I know you said you checked everything, and no leaks (that you can see).. But the pedal would go all the way to the floor and then finally get some braking power.. I had a leak in a brake line.. Are you losing any brake fluid, or is it staying at the same level?

Walk us through your bleeding sequence and what your problems were before the bleed and what you did to fix them.

If your sure there are no loeaks and bled it properly check the adjustment of the rod connected to the brake pedal. For whatever MC you have installed you may have to adjust it so the length is longer pushing into the MC further.
Just something to check along with everything else.

calipers
No mention of what kind of car you are working on..but I assume that it has disc-brakes at least up front. With the wheels off and applying the pedal, do the calipers close evenly or do they look like they are rocking or tilting? If the caliper sliders are rusted (and stuck), you'll have the symptoms you mentioned. Won't bleed, will pump up a little, but will eventually go back to the floor.
This goes for brake cylinders also...but I suspect the front calipers are stuck. New pads and rotors won't make a difference. Rebuilt calipers aren't really that expensive anymore (for most GM stuff anyway)

I have a feeing you have a lot of air in the system. Keep in mind that with excess air it may take four or even five good bleeds to get all the air out.
Buying a bleeding system like a vac gin or a Motive is a good idea, but you can get the same result from a good old fashioned bleed.
I'd bet the guy that replaced the master did not bench bleed and there was a TON of air trapped in the system after that. You bled, but maybe only got a fraction of what's in the system.
Bench bleeding while the master is in the car is a good idea too.

Another thought here....if your M/C was "by-passing" it's seals, after sometime the brake fluid would warm up,and seals would expand and your pedal would pump up.....on the other hand,if your pedal stays soft...(low to floor) even after driving, then I would agree your "bleed" is not complete,and air is still in your system....
I just learned that recently....
