The reason for that design is the fact that the shoes wedge up and that is
what really puts the force on the drum.
When we were testing and recording the rear Drum /Drum Reaction Arm Kit,
the wheels were skidding on the inteermediate wheels several times. I was
upset at my guys for not adjusting the shoes properly and brought it back
and I inspected them and readjusted them.
So when we re tested them , same results.
Called Tom Pryor and explained the phenomena.
He did not have an answer then , but requested time to figure that out.
Bottom line was that the Disc brakes can be charted as to when it will
grab, while the drum shoes cannot be charted as there is no way of knowing
when it will grab.
