I had an aftermarket pacbrake installed on my 01 Ram. It has an air pump. When I turn it on it takes a few minutes for the air pump to build up and the exhaust bake to be maximized. I supposed it has to build pressure to be able to close the baffle. Not sure any are made to work instantly. 18 wheelers take a few minutes to build up air. Maybe the factory brakes work electrically and don't need this air build time.
Why isn't the air compressor (and perhaps a storage tank) on all the time the ignition is on and controlled with a pressure switch? That way, the exhaust brake is available instantly. That is EXACTLY how I would wire it.
May be ok but the air is a benefit of the exhaust brake and not the intended function. Don't believe I would want to run all the time just to keep air tank full, if a tank was added. Anything is possible. The way it functions now is not a problem for me.
