i have pics on my camera but my wife has my camera.
on the right side rear of the frame, a little before the rear end is a...brake valve with with a rod going to the opposite side of the frame. what is it and do i need it?
it is a weight bias proportioning valve. It adjusts the rear brake pressure to the load you have in the bed. You can remove it but you should completly remove it and not just the rod.
use another tee like the one on the axle. some advocate the use of a proportioning valve, but if you're using the stock drum setup in the back, the tee will be sufficient.
