Are the typical adjustable valves like Wilwood etc. Just a needle valve ? Reason for asking is that I have a 1/4" stainless 6000psi Hoke needle valve in my shop. If this can be used I don't see any reason getting another one.

Here are a couple of articles that explain brake front to rear bias and why proportioning valves can be required:

I will not or don't have any intetnions of doing a short cut. I found the speedway motors valve http://www.speedwaymotors.com/Speedway-Compact-Adjustable-Brake-Proportioning-Valve,1979.html and it made me thinking. I also saw a valve of same design as the one on link i posted. (The small one on bottom of page) fitted to a camaro a few weekends ago.
