Definitely. Braking habits, topography, community - lots of reasons for mileage to vary.

Also, changed the front caliper as I was too frustrated with its performance of it and sticky pistons - no matter what I did. Was very frustrated with it and decided to just get a new one. Only realized that there is a rebuild kit for them and its quite easy to rebuild them. Truth be told, I also snapped a mounting bolt on it with my f***up torque wrench. Lots of lessons were learned in this work.
I've never sanded down my rotors, though I've sanded down my pads once in a while, when they've been contaminated.
