As a general rule I replace instead of resurface. Why?
- The price of new rotors these days is relatively inexpensive.
- Modern rotor design is typically quite thin and given that the thermal mass of the rotor is already borderline not enough (especially for our vans), and given that resurfacing (or cutting or turning or shaving, same things) removes even more metal from the swept area (thus further reducing the thermal mass), I always recommend new rotors.
- I typically avoid OEM rotors as they're typically very expensive; if you shop around you should be able to find rotors which either meet the OEM spec for considerably less money, or rotors of superior metal composition (thinking brands like Brembo) for roughly the same money as the OEM units.
