Cool project !

I had a similar problem on my brakes that turned out to be a steel hardline was clogged going to the rear brakes, took forever to figure it out.

First If you haven't already, replace the rubber brake lines at each wheel. They like to swell on the inside restricting flow of the brake fluid.

Once I did that and the brakes still didn't work properly I disconnected all the hard lines and blew compressed air through them to make sure they were unobstructed and ah ha! the steel brake line was clogged. I replaced the hardline and the brakes started working as they were supposed to do.
