Since the car came with manuel drum brakes, I would go to NAPA and purchase a new stock master. Try to keep everything like it came from the factory. The drum brakes have like a 3lb. valve that keeps pressure on the lines that disk don't have. I think part or all of your problem has been intermingling drum and disk parts. Go back to the orginal setup and you should be fine. Make sure that the master is for 4 wheel drum brakes since some cars had disk on the rear and drums on the front or disk all around. None of these will work properly. Also, be carefull you don't get a master for power brakes, it won't work right either.
