Just hit 70K on stock rotors and pads, the pads still had about half life, the rotors looked really good too. Our stock brakes hold up pretty well. I was hearing squealing only when slowly backing up so I decided to replace rotors and pads. It must has been the massive amount of brake dust causing the squealing, swapped front/rear rotors and pads no more squealing. I drive very aggressive, I also downshift when slowing down to conserve brake life.
