Hi everyone, I have a 89 camaro that came stock with disc/drums. Now it has c6 dual piston corvette fronts, 4th gen rear with pbr pistons out back, and a 4th gen MC. Now Ive searched everything and everywhere but can't find an answer. Do I need a prop valve if I have an adjustable one on the rear? Like can I run straight line to the fronts and have the adjustable in the rear? And if I can't, will the 1le prop valve work with my setup. I've looked for 4th gen prop valves but all of the are ran thru the abs module. Car stops amazing now. Do I even need to change. Any help is appreciated.

 

If it stops amazing now I would just leave it alone. The C6 fronts and the pbr rears probably are happy with the same pressure difference the original disc drum combo had.

 

race cars don't have prop valves.. street cars have prop valves to make it easy to mount the federally mandated brake warning light switch and cut down pressure to the rear brakes to keep Joe Average Dirtball Wanna Be Race Car Driver American from killing himself and other people when he slams on the brakes in a corner and loses control..
