Disc Rotor Thickness

["Chris Leah" <crl@intekom.co.za>]

Hi all,
I need to skim the disc rotors on my Spitfire Mk2 and can find nothing in
the Factory Manual or the other books I have to tell me the minimum
allowable thickness of the rotor. The car has done over 100 000 miles and I
am not sure what the PO's may have done. I would hate to have the rotors too
thin and see large volumes of smoke from the front end under braking!
Thanks in anticipation.
