the proportioning valve is for emergency braking in oem application.

if you break a rear line, inside the valve a piston moves and blocks the rear line, so you still have front brakes...

thats all it does in stock form.

take it completely out for race use. if its in you need to read a chiltons manual on proper brake bleeding. theres a button on the valve like a reset.

Has anybody run a residual valve for the back brakes ? and is it worth puting one in ? this is a metric with front rotors and drum rears. thanks Jim

Yes, run the residual valve. Without it you will have more front than rear brake. I've fought that problem for years until sleepy talked about it here. With the rear adjusters hooked up you will have close to even braking front to rear.
