Nope, what he is describing is a proportioning valve that adjusts the rear bias according to how far the suspension is loaded down. I did away with mine because it no longer functioned and I didn't like the idea of three brakelines running to the rear when only one is needed. I replaced it with a manual proportioning valve in the engine compartment.


Probably alot. I've always managed to keep it topped off pretty well. I don't have a backup vehicle either <img src="/forums/images/graemlins/smile.gif" alt="" />. The other truck in my sig. is sitting in heated storage right now with the front leaf springs pulled out. That truck's my baby <img src="/forums/images/graemlins/baby.gif" alt="" /> <img src="/forums/images/graemlins/wink.gif" alt="" />.
