What is the minimum thickness that rotors can be machined doen to?

I am looking for the minimum thickness that the rotors must be (front and rear) on a 89 SC so that they can still be machined down. I know that if they get too thin, that they can't be machined anymore.
Would someone be able to help me out with this?

Thanks,
Stephan

Usually, the number is engraved on hub part of the rotor itself somewhere. My best recollection is the number 0.950" for the front rotors but I don't know about the rear rotors.

Wagner spec. book I have shows .935" for the front, and .895" for the rear of an 89 SC.
