So my "Air brake" endorsement on my license is a plot to get more $ from me by the DMV? I knew it!
Seriously though - actually and technically, (and
extremely nit-picky) both types are friction braking systems. They both rely on an external force (air, hydraulic, positive mental energy - doesn't matter) to the friction medium by a mechanical link of some kind (levers, cams, pistons, push rods, bailing wire). So unless you’re absorbing the energy directly by air or fluid (think torque converters) how you apply them is irrelevant.
Whee!
