Brake air pressure measurement

I have a 2008 Itasca Ellipse, and am familiar with the brake air pressure sensors.

The sensors are on the dash gage, and air lines are run to the back of the gage.

Unfortunately, it is a bad design and the plastic housing cracks and a leak develops. They are very difficult to repair. They were redesigned several times, and the latest ones do not have the pressure sensors built into the dash gage. Even more unfortunately, Freightliner has sold all of the gages and they are no longer available except for a few that various dealers have squirreled away. The price has skyrocketed from $250 to $2500 (when you can find one).
This may not be your problem as I didnít fully understand your description. If other gages have gone out as well, then your problem may lie elsewhere. I suggest you call Freightliner Customer Service. (800) 385-4357
