No Break Pedal
Have you made a brake test on test stand?
I think you also have to rebuild at least your driver side caliper, if a piston is clamped inside.
Sorry for my bad english... I'm from Germany.
If your pedal was soft before the pad swap it is likely a bad calipar or master cylinder seal. Is there any sign of leaking brake fluid? If not, it is probably a bleed issue with trapped air in the lines. You can bleed like hell but not get all the air out.
Try a reverse brake bleeder that forces new fluid up from the caliper bleed screw up to the master/reservor.... these tools are cheap ($25 USD) and work very well. I would never bleed without this inexpensive tool again.
