47 brake problems

[exoilfld]

On my 47 pu, I have new drums, shoes, wheel cyls., line, hoses, and master cyl. Adjusted the shoes as tight as I can make them and bled the system 3 times. the first stroke of the pedal goes almost to the floor. The second stroke gives a good hard pedal. The only other adjustment I can think of is the master cyl rod. I left about 1/8 inch or less play before it starts pushing the cyl. Anyone have any ideas?
