Another brake question

[Ghost's68]

Hey guys I got a question about my brakes. I posted earlier asking for help ID'ing some rear components. I was able to replace all the parts but here's is where my question comes into play.

So after power bleeding my brake system using a motive bleeder, I can't get the brake pedal to stiffen up. It just keeps going to the floor and when I try to stop the vehicle I put my foot damn near the floor with no lock up what so ever.

My dual M/C has a separate lines that runs to the front and the other to the rear. The lines from M/C do not go to Prop valve of any type. They go straight to the caliper. Am I missing something?
