See what I mean. The only effect would be if you were running the size of caliper pistons way different in size. That would make one brake much sooner than the other.
Next, you only need a 2 psi residual valve in line running 4 wheel disc. It looks like you have more than that by the picture. The last thing if you have a gauge, you can connect that to the master cylinder to check to make sure the master cylinder itself is not faulty. I asume you have the booster and master mounted on the firewall by your picture ?
If you were running rear brake shoes, the springs hold them off of the drum. And the travel is controlled by the adjustment of the rear shoes. I'm sure you know that, but thought I would throw that in as well. hahaha.
