Technical Update: 1948 oldsmobile brakes

Ok double bowl mc under floor new rear drum brakes front disc brake conversion residual valves installed new lines adjusted brake pedal bled system 100 times still no pedal still no brakes ????

 

Residual valves in backwards flow position ? (Installed wrong) I wish I was at your place right now to help double check the brake system and bleed brakes again.

 

How about some measurements so the experts can give some helpful advice?

 

I have seen some bad masters lately, right out of the box, NG.
