Like this?In the bad old days they looked more like this, and didn’t have no keypads or light-up numbers (and you wrapped a belt around the drum so it wouldn’t ring:

A lot of the warping has to do with the old machines. They are easy to chuck it up not straight and even if you got it perfect it doesnt account for an out of true wheel hub. It’s not the warping you feel but disk thickness variation which comes from warping. The warped rotor scrubs the high spot every revolution until it’s no longer high but the back side will be low from the warp. This causes it to be thinner at the warp. You feel the hydraulic action of this since fluid doesn’t compress. Turning on car means that it’s turned at a run out of .001 or less. So it’s starting off straight to the wheel bearing hub. They last much longer.not to mention that if they already warped once, they'll do it even quicker once they've been turned thinner. I just replace them.
Fords. The quality of the cast is terrible but they ate thick enough to turn a few times.What cars are you working on that still have rotors thick enough to turn? I gave up on turning drums and rotors nearly 20 years ago. Both were so thin from the factory there wasn’t enough to turn if they had more than a deep scratch
The machines now sit in a friends auto museum.
It’s just working on becoming cross drilled the natural way. They look pretty cancerousi didnt get these turned but im guessing the previous owner did.... 08 f150
