It looks kind of like air brakes are not a very efficient system, especially in an emergency. Why aren't they hydraulic brakes? Most likely because they are cheaper to build. Any disagreement on that?
I have a question about 'draining' the air system of water. How important can it be if they hide the pull cords behind the front passenger side wheel/tire? You almost have to remove the tire to get to them. Lying on the ground, I used the awning crank but couldn't tell if those drain cords moved or not. Should they hiss at me?
Advice?
