New brake system - no pressure...

RRR - I'll check the attitude of the master. I know it's supposed to be parallel by it's design but the car is on stands and may be biased nose up. Not being hard headed about stroke but if it pushes fluid from beginning of pedal contact and goes to the floor an adjustable actuator pin does help and that's why I eliminated that early on.
Rick - Funny you mentioned that. I do have the calipers switched because when you convert a drum car to disc with early 70's single pot calipers you have to if you run a sway bar. I may have to put a block in the calipers and leave them unmounted to optimize the bleeder attitude. Wouldn't I still get pressure from the rear brake circuit?
