This is the common complaint with Shimano (and perhaps other brands) and has been my experience as well. Where I live, it seems to be cool to put a stop sign at the very bottom of a hill. As a result, I'm on my brakes really hard to come to a complete stop and when I start moving again, one or both rotors start rubbing for a while which eventually goes away. It's my understanding that the new 12 speed Shimano group brakes have a very slight increase in pad gap distance to reduce the rubbing noise caused by the tight pad clearance.
