Seriously, please, i have a similar booster. all you have to do is pop the master off. You'll see a small stub in the booster hole that should have a hex shaft. That's adjustable. It actually pushes the master's shaft. You should feel it make contact juuuuuust before the master bottoms out on the booster, but you should feel it. Look up master cylinder/booster engagement. They make a tool, but I just did it by feel. I had mine way too far engaged, and the fronts would lock themselves in a couple of miles. I got it all set right, much better now.
