Looking at the pictures above, I am interested in your brake plumbing. I have purchased the same master, and I am switching to front disc brakes from a single master four wheel drum system, so I have to redo the plumbing. It looks like you are using an adjustable proportioning valve and a combination valve? Are you running the rear line directly and just using the combination valve to split the front lines?
