I watched it a few more times, there's a pogo stick with air lines going to the trailer. I wonder how the brakes transition from hydraulic to air?

Interesting find!

That's got me asking myself more questions, like is that transition valve adjustable to input or output pressures to calibrate braking pressures between the two systems? Seems like there would be a need for that. I laughed when he grabbed that big lever on the floor, I guess that's the treadle valve?
