Has anyone had a vibration in the front when brakes are applied. on 2003 Cadillac DeVille

I have been experienced a vibration in the front at the time of braking. this is a 30,000 mile car so all of the normal reasons from wear do not apply.

YES SOUNDS LIKE WARPPED ROTORS
Normally I would agree but this is not every time you try to stop. It is not all of the time mostly from highway speed to brake. almost never at slow speeds.
slightly warpped rotors magnify at higher speeds. like getting off a freeway off ramp
Thanks you may be right, I guess I'll have them turned to check for that.
no they usually warp because they are to thin replace them
