What . . . more of an air-brakes man?! Different beast all-together, isn't it?! Or do you tend toward the older, mechanical brake stuff?! THAT will test your skills, for sure! I think air is probably easiest and most trouble-free, hydraulic after that, and then mechanical. Of course, if bell-cranks and rod-straightening are your thing, then mechanicals are for you . . . ;-)
