[B]My 3 coin rule
If your brake light is on and you have a lip whose thickness is no more than that a "Dime" - I might used them again.
"Pennys" - its about time to change them
"Nickel" - Regardless brake light or no hurry up and change em'
Here are the official thicknesses of the US coins:
Penny 1.57 mm
Nickel 1.98 mm
Dime 1.35 mm
You method looks spot on! Another post mentioned that for his rotors, original thickness was 25mm, replacement thickness was 23mm!!
