    So I hate to sound stupid, but this MC has a proportioning valve already in it, right? specifically for a disc drum setup. Also, did the actuating rod need any modification?

    If you look at the link, there is a kit that includes it all. I am not Herm, nor do I have any affiliation with him or his products. You might want to point your questions to him, as he builds these kits. I made my own before I installed hanging pedals, power brakes and 4 wheel disks on mine.

    It took me much longer than expected, but I finally got my brakes working again. I used an MC from a 1975 Chevy Monza, which required me to swap out the push rod, enlarge the mounting holes, and make new brake lines. The ports are on the driver's side, so it is a pretty tight fit. I also had grind a bit on the lid because it was contacting the frame. This MC has no residual valves built in, so I added Wilwood inline valves - 2 psi for the front, and 15psi for the rear. After that, I found that my rear brakes locked up long before the fronts, so I added an adjustable proportioning valve to the rear brake line.

    With everything dialed in, my brakes are working better than ever. The 3/4" bore MC requires about half the pedal pressure as the stock 1" MC for the same braking performance. This also means twice as much pedal travel, but with properly adjusted drums that is not an issue. I am very satisfied with this setup.

    I should be able to get some pictures up soon.
