Assuming you went furthest from master cylinder to front, everything you did sounds correct however, the output of your effort points to air in the system.

Since the air/gas is MORE (thanks admranger!) compressible than the fluid, it would make sense that you can eventually build up pressure.

There COULD be some other issue causing your symptom like a leaking master cylinder. The caliper you replaced could also still have air in it since it was new.
I think activating the ABS is the key...working on the software install. I'll let you know how it turns out.
