Drum brake issues

Hi all, I'm posting this in this board as I think it sees more traffic. This is a drum/drum 69 Blazer.

On my Blazer, I'm trying to get the drum brakes to work, but I'm not having any luck with the Master Cylinder. Its new, but I'm not sure if its good or not. Had to adjust the length of the push rod and it doesn't seem like I'm getting fluid out to the front brakes. When I try to bleed them, no matter how much I pump, I never get pressure and only a little fluid comes out at the bleeders.

What am I doing wrong? The backs work fine, pump up, bleed no problems. Is my push rod length off? How can I check to see if its long enough to be activating the front brakes?

Thanks for any help, Jeff.
