It depends on your driving style really. Highway vs. city. More city driving usually means rotors replaced more often. Odd you had to do rear brakes before front brakes. Majority of braking comes from the front end. But anyway, signs of failing rotors are a low grinding noise when braking or a wobble in the steering wheel/seat when breaking.

Due to the abs/ESP systems the rears do wear quicker than the fronts. Look at getting your rotors turned to get more life out of them. My front pass. Needs replacing real bad due to a rock that got stuck better the shield and rotor. I have gouges that are easily between 1/8 and 1/4" deep!

I replaced my rears (pads and rotors at about 30K miles. The original rotors looked fine on the braking surface but they were, for lack of a better word, delaminating. On the plus side, the replacements were cheap. I'm still running the original OEM front pads and rotors........they hardly look worn at all.
