Hey, I've got some questions about making my own brake system. I've never done it, but I'm gonna learn, so here goes.
I'm planning on running all new brake line. Actually, a whole new system from MC to axle. But my main question is this:

I need to install an adjustable proportioning valve in my system. All the valves I can find have 1/8 NPT fittings. I have a 3/16 system. How does that work, or where can I get a valve with 3/16?
