proportioning valve lines

Just to make sure, does the line that goes out the back of the pro value go to the rear brakes? Been a few years since I took the truck apart. Any pics of the lines along the frame would be helpful.

Re: proportioning valve lines

What year? Discs or 4 drums?

My 4 wheel drum is front to front and rear to rear.

Re: proportioning valve lines

i believe that you are correct. i have a cpp prop valve for 4 whl discs & the line for the rear brakes connects to the prop valve at the "rear" connection by the booster. now if i could only get it to not leak!
hope this helps.
