I wouldn't worry. The factory pads are sintered, too. Steel rotors handle them just fine. RM

Mike; You can choose where the wear occures, but wear is wear. You have X amount of energy in the form of momentum (kinetic energy). You use friction to convert that into Y amount of heat through your brake system, producing Z amount of wear. Softer pads will put most of that wear on the pads, not much on the rotor, harder pads transfer more of the wear onto the rotor. While I know it happens, I've never known anyone, or talked to anyone, who had to replace a rotor due to normal wear alone. Since I never expected to be able to wear one out, I always used harder pads to reduce the number of times I had to take the time and effort to replace them.

But Z is not necessarily related to Y. The mechanisms via which friction is produced between brake pad and disk are still under investigation (current compounds were developed via a process of trial and error rather than via scientific understanding of the friction mechanisms involved), but often involves adhesion forces rather than materials decohesion and removal. Decohesion is not a necessary part of braking (though it happens with all current brake pad/disk setups), otherwise eddy current braking (used by, e.g., rollercoasters) would not work.
