You say you're using a "stock style" master cylinder. Is it a disk/disk master or disk/drum?
I got the MC/booster combo from O'reilly's and I ordered it for disc/drum.
That's your problem. You will never get the brakes working properly if you're using a master cylinder designed for rear drum brakes when you're actually using rear disks. You NEED a Disk/Disk master cylinder. That will solve your problem.
