Drag car brake/proportioning question
I built the brake system on my Duster and so far it seems to work but I haven't done any high speed full brake tests. I used 13 inch rotors up front with Viper calipers and a Ford Motorsports Explorer disc brake kit in the rear. I used a Baer billet master cylinder with a built in prop valve. At the moment I have the valve fully unscrewed so I have full pressure to the rear. I'm not sure that I need a prop valve in my Duster but the master cylinder came with one so I plumbed it in. When you custom build cars you have to be willing to try different things to find out what works since there isn't a blueprint. It isn't like restoring a factory car where someone has already done the design work. Store bought kits might not work since your car might have a different weight or a different weight distribution from what the kit was designed for.
