Whenever you get your rotors turned and new, or same pads, you need to let them brake-in and seat. A mistake that some people make, is to reverse and slam on the brakes multiple time thinking that will adjust the breaks, or do the same thing in forward. That can warp the rotors if they heat-up too long and fast. It's like when you get a new Ody, you should avoid heavy breaking for the first couple of hundred miles to let the brakes seat themselves. Also, it's always good in mountainous areas to lay off the breaks as much as possible since those long downhill runs can really heatup the breaks and potentially warp them if they repeatly get really hot.

I just had my front rotors turned and the rear pads and rotors replaced at 6800 miles by the dealer as part of the 3/30. The shake when applying brakes was really bad. No major downhill runs or anything, just highway and back road driving. Seems odd although I've had other cars that had the same issue, just not at 6000 miles.
