Now, testing my logic, I don't know how 6.7% more brake lining surface can create 71% more braking power (ie, the ability to stop 12000 pounds with the Airstream brakes vs the ability to stop 7000 pounds with the Dexter brakes, as cited from Andy's data). Can anyone explain this to me, or at least do as my third grade teacher used to do, and put me in the corner on a stool with that little pointy hat.
Thanks.

The stopping power numbers I posted, come from the manufacturers of the electric brakes.
Also the larger the brakes, the less the brake fade from heat.
