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?

Yes I am using a factory style Proportioning valve, i am not sure if it's actually considered a combination valve... I would have to go back and study the many Richard Ehernberg articles on that one to be sure of the correct vocabulary.

I removed the t from the old single pot system that was on the driver's frame rail.
The brass prop valve gets plumbed in as any typical one would. Yes it splits the front brakes for LF/RF.

The rear outlet goes into the adjustable Prop. Valve and then the output of the adjustable Prop valve goes to the existing rear brake line.

I am not 100% sure that's the best / most correct way to do it. It works fine for me and has hauled the car down from 100 mph on the straights at CMP in April 2022 so I would say its safe and functional.
