How many miles? What kind of driving?
Probably 3-4K, easy driving, mostly open roads, easy stops.
I have trouble understanding how surface area does not factor into the equation for stopping power. If that is so, why don't we just use a 1 inch rotor and pad? A few months ago, I noticed that the contour my daughter drives had very weak brakes. Upon examination, I noticed that only a small portion of the pad was contacting the rotor. I could tell by the shiny vs rusty area of the rotor. I put on new pads, and the problem was solved.
It's been a long long time since I had a physics class, but I thought the coefficient of friction multiplied by the surface area resulted in the total friction. Maybe I'm wrong, I had that class 34 years ago.
