Grant, you must be right.
I thought I had seen pictures of the trailer air brake line setup on this forum before. I recalled it was for actuating trailer brakes, not boosting thr truck's brakes.
If it was a pressurised system, the truck would have to be equipped with a compressor but I see no signs of that.
