The farther away from the center of the axle you put the caliper, it is more able to exert greater forces. (moment/arm) sort f like putting a chater on a torque wrench to get higher torque.
in other words, 1 foot lb is exerted on a bolt by using a 1 foot bar, and pushing down with a 1 lb weight.
If you use a 2 foot bar, and push down on the bar with 1 lb, it is 2 foot lbs. if you have larger rotors, and the calipers are farther from the centerline, and more force is transmitted
I couldn't work that one out either.I just thought bigger was better!!!!!!!

Sigh. I was not referring to replacing a 12" rotor with a 13" rotor. I was referring to using drilled and/or slotted rotors in place of blanks.
