Correct. They commonly go bad too so if you have brake problems, bypass it. They never worked that well anyways.

My 88 3/4 ton burb has one. Seem to function on my 88. You correct, it put a little more brake to the rear as load causes the rear to drop.
When I have my Cargo trailer and a load in the burb I do notice a change in the brakes. I had a brake pull from a stuck adjuster in the rear that became VERY apparent with load but hardly noticed it empty.

Yeah my rear shoes are super thick and i just put new carbon metalic and rotors on the front it stops good the pedal just goes down more than i think it should
Did you bypass yours? It has a prop valve up front too Im just wondering why it has this and what if the other prop valve puts 100% to the back and this second one is supposed to do the rest. |
