Minimum rotor thickness

I have a 2004 Ford F150 4WD, Supercrew, 5.4L engine. Can anyone tell me the minimum rotor thickness for the rear brakes? Local Autozone told me .787 but that isn't close to what I measured, .615 to .630. Thanks.

18.5mm or 0.72 inches. Sounds like you need new rotors.

Minimum thickness is sometimes stamped on the rotors. I believe mine were. Sounds like you should replace them.

I just bought this truck a few months ago, evidently the dealer and the previous owner didn't check the rotors. Yes, I went ahead and replaced them, although they were rusted and stuck on. Thanks for the help.
