A. TAKUSHI, why did you quote yourself? (Twice)
B. I'm not going to theorise on the implications of skimming brakes, because theorising has already been done...
C. From my 1st hand experience, when i imported my car i was told "all of your rotors need to be skimmed", 3 years later... same rotors, same pads, no skimming, still going (40,000kms.)
Anyway, if skimming was sooooo bad, why would it be an option?
