Tri5 Drum to disc conversion bleeding problem

I bought the drum to disc conversion for the front of my 55 Chevy and changed out the hardware that came with the kit and I also changed the rear drum wheel cylinders for good measure. I am now having trouble getting the system bled and the pedal will go to the floor on the first push and then will stop about an inch from the floor on the second push of the pedal. I have bled the master cylinder again and the wheels multiple times, still the same result. Has anyone else has this problem and what was the solution?
