Brake Bias Valve

[bigb]

Can anybody confirm exactly where the brake bias valve is located on a Griffith. Mine is a 98 model and I think I've located it at the top of the chassis, above and rear of the diff. The brake pipe running down the length of the chassis tube feeds into it from the front of the vehicle and it then immediatly feeds into a tee piece and splits left and right.

Any help would be appreciated.

Yep it is located in the back. Not adjustable which is one reason why it is there.
