64 Avanti brakes

[Shoovel]

Folks,

I need your help. I’m working on a 64 Avanti without the “anti roll” feature. 
I’ve replaced the front caliber blocks, rear wheel cyl, front & rear flex lines and master cyl. I don’t know what I have done wrong, cause I can’t get any pressure when bleeding. I tried having my helper push down on the pedal and hold it to the floor, I got air out of the RR, and LR, then RF and LF, but I cannot get any pedal. I had my helper pump the pedal with the same results. All parts from   Studebaker Intl.

Any help will be greatly appreciated. Thanks.

Being you changed the master cylinder, I'd probably start with assuring the clearance between the end of the booster rod and the seat of the master cylinder piston is within spec's.  If you're uncertain, a tool is available which is used for this.  Good luck.

I agree with Mel…. the booster rod is probably adjusted short.
