You read the machine right and I've seen the same thing when I turned
rotors.

My "opinion" based on what I have observed, what I know and the article we
both read is that "warped rotors" are probably rotors that are just thinner
in some areas than others. And since rotors are turned one side at a time
there is no way to correlate the observed warping with thinner & thicker
areas.

Subject: Re: Why Bigger Brakes Was Cause of brake rotor warping

Hey, I got my warped rotors turned!  The auto tech instructor at the college
where I work let me watch while the first one was running.  You could see by
looking at where the cutters were taking material off the disk that it was
warped.  By warped I mean the places the cutter was removing material on one
side was the opposite of where the cutter on the other side was removing
material.  By opposite I mean around the circumference of the disk.  Like at
12 o'clock vs 6 o'clock.  The article linked earlier seemed to indicate this
was very very rare.  Or did I not read that right?
