Stop and go driving on the freeway is the worst offender IMO. With all that stopping, you tend to come to rest at the grippiest spot on the rotors, which adds more and more deposits to the same spot on the rotor.

My Dad went through like 4 sets of rotors on his T-Bird in the first year of ownership due to his stop and go commute from San Ramon to Fremont everyday. When Ford stopped replacing the brakes under warranty, he just stop worrying about the brake shudder and ignored it. When I got the car years later, I went out and hammered on the brakes, and wouldn't you know it, the shuddering went away and never came back because I never drove the car stop and go.

I'm actually noticing a spot on the brakes on my truck, since I've only been driving it around town. But I expect they'll clean right up the next time I have to tow anything.
