Testing the output pressure of a Master cylinder

First test on a brand new AC/Delco unit provide the required psi and then some. I think it tested 1100/800.
After reading this thread, I need to bring it back to the top with a few questions. How do you actually test the output pressure to these master cylinders? Is there a "test kit" sold at the auto parts stores that screws into the master cylinder ports to test the output of a master cylinder?
I put a re-manufactured 10-1371 on my M725 last fall, and now I'm seeing that I should have used a 10-1331 which has a 1.125 bore. And, with the 10-1371 with a 1" bore, I do not have aggressive braking that I think I should have. I have HUMMER tires and recentered rims on my truck that I am trying to stop. Am I asking this master cylinder to do too much? Are these two master cylinders inadequate for this larger tire application?
Any advice? Thanks in Advance,
What vacuum booster would you pair with the 10-1331?
This is a great write-up. Thanks for sharing these details. I'm renovating the brake system in my M715 and following your instructions. If you were to add a vacuum booster, is there a booster that would pair nicely with the 10-1331 master cylinder and fit into the M715 without modification?
Any advice is appreciated.
