Rolls Royce Turbo Jet Engine for Blue Birds

[Jeff Miller]

Actually George, the drive axle does most of the braking on a heavy
vehicle like the Wanderlodge (including buses and trucks), very
unlike passenger cars.

The steer axle doesn't have as much tire, as much weight, and
therefore smaller air chambers to apply less braking force.

The spring brakes will not apply as much force to the brakes as the
air pressure will in most cases, designed to avoid lockup.
Regardless, I don't recommend using the spring brakes to stop a coach
other than in an emergency.
