Brake Rotors, Replace or Resurface & TOLERANCE ? -- hi - Son has a 2006 Sonata GLX, 6 cyl. Has some pretty minor pulsating when braking at 70-ish (which is rare. He does not drive that fast, I just did it for testing). Otherwise he is getting what I call normal squealing noise as the front pads need to be replaced, rears are close enough to replace since it will be up on the rack anyway.... car was bought used at 47k miles has 100k on it now. Normal driving conditions.
The mechanic just said replace rotors (and probably calipers) without even looking. They quoted $325 front and $350 rear - without calipers. They said can't resurface OEM rotors as they are not thick enough. (I told him to find a new mechanic).
Can the original rotors be resurfaced? They appear fine, very minor pitting some minor track worn in the fronts only.
What is the tolerance for thickness? I cannot find that info tidbit anywhere! I can measure them, but need the minimum thickness tolerance per Hyundai specs.
What is difference in cost to have the rotor resurfaced vs. replacement. Back in the days I worked at Ford dealerships, they just set the rotors on lathe and walked away to get ahead of the book job labor hours.
