Vincent ,
What drums are you referring to ??
Alloy drums of the 403 with cast iron linings, I suggest .060 max oversize, as when the liner is too thin it tends to crack and even loosens in the alloy drums.
Cast iron drums could be taken out more but a brake specialist should know what the appropriate government safety regulation is regarding the max. oversize they can be machined. This could vary state to state in Australia.
I also suggest the largest oversized drums be fitted on the rear axle and the smallest on the front axle.
There are also government safety regulations on machining of disc rotors .
