Tiger brake specs

[GRMTim@aol.com]

I've just been through two service manuals and can't find any specs on 
minimum brake drum and rotor thickness for a Tiger. I was going to replace 
everything, but found out rear drums are unobtanium and front rotors are nearly 
$200 
each, since they have the hub built in. Since stuff is so hard to get, I 
thought 
I would at least see if I can turn what I have, as it is off a low mileage 
car.

Does anyone have these specs?

Thanks,
