I thought my car was suffering from uneven brake pad deposits and even drove for 2 weeks to see if it would go away. It only got worse.
My rotors were actually warped from 2 track days. I removed them, put them on a lathe and measured the run-out which was considerably enough to make me concerned. I cut them down and all is well and they have enough to remain within specification after another cut.
The juddering is not always pad deposits, the rotor will warp easily with stock pads if you are pushing it enough.
Both track days were at Big Willow for reference.
Here is a video for fun of one of the rotors I was resurfacing. You can see how badly the rotor was warped in the video, even though it had been cut once at slow speed. The 2nd slow speed cut made it perfect.
