It mounts in the cab and allows the driver to control key air and brake functions, including the parking brakes and trailer air supply. This valve is typically replaced when the dash controls become erratic, air leaks develop from the knob area, or the valve fails to properly apply or release the parking brakes. While commonly found on Freightliner applications, it also cross-references to several other makes.
