Could you explain the issue a bit further? Maybe some pictures?
i suggest reading the article. A lot of people don't believe it, but many engineers say it's not possible to warp rotors with braking. You would need to hear them so hot that the tires caught on fire, and then quelch them with cold water. I recommend having an open mind before just dismissing this because you have worked on cars before.I've been working on cars since I was 17/18. Trust me the rotors were warped, it had nothing to do with loose lugs which I always torque to 100ft-lb in a star pattern....
And pulsing was probably a better term to use than shutter
