At work we have a few hundred 'tugs' that pull around the baggage carts and some have brakes that will put you into the windshield and some that will put you into the side of a plane..
I guess it would depend on your foot 'till you get the feel of it. But if someone built up a 'big brake' setup, they wouldn't have to worry about fluid pressure. I guess a adjustable proportioning valve would be a must.
I'll see on this Hornet later this spring when I start tearing into it.
Another thing I thought of was to use an adapter at the rear or bumper that one could extend that high pressure to a trailers braking system that would have one way valves.. Just a thought though.
