Can rotors be re-surfaced more than once? (brake, buy, replace)

[veritasveritas]

Depends on the condition of the rotors. It can be resurfaced twice as long as it is within manufacture specifications. I personally would replace them.

No need to either replace OR turn, unless there's an issue w/ them.

"Rotors have a minimum thickness specified, often marked on the rotors themselves. If after turning they are still thicker than the minimum, feel free to use them."

This is a true statement.

Rotors are cheap these days because parts store rotors are made in China cheap garbage that you have replace every year or two.

If you want quality made in USA rotors you have to pretty much order online from companies like EBC and Stoptech/Centric.

Had them turned more than twice. That's to OP question.
BUT!!! New rotor should be bedded in and never have pads material build up thereafter. Rotors do not warp, unless they are them cheap China made ones everyone here slaps on. Not bedded rotor will have uneven brake pad material build up resulting in uneven braking and shimmy.

The only true way to answer it is by knowing what the minimum thickness is and what the micrometer says.

Period.

However, some cars have inexpensive rotors and replacement makes then most sense.

I've spun rotors in the past and had no problems, but they were still thicker than the minimum spec after doing so.

For a car with cheap rotors, I'd just replace them. But if you've got some large, expensive cross drilled performance rotors on your car, you can probably turn them at least once and they'll be just fine.

unless you got some carbon fiber high end rotors most rotors are cheap to replace

If it was my car, I'd throw the rotors in the trash and buy new ones anyway. I personally like brand new rotors regardless of cost. Granted...I'm not driving a car with high end brakes, so my POV pertains to the "normal" stuff.


I gave up resurfacing rotors a long time ago because 1.) hard to find a place that would do it for me, and 2.) most often the rotors were at min thickness anyway meaning they couldn't really be cut.

A Toyota dealer resurfaced the front rotors on a truck I used to own, back in the early 90s. The truck had few miles on it, all of them highway miles, and it was a manual transmission. In other words, I did less braking than an average driver would have. The shop guy told me they advised against having the rotors resurfaced again because they were thin.

I was surprised they warped that quickly, given the truck's lack of city use and the fact that I downshifted on steep descents, which worked well. The clutch did not need anything other than one adjustment, much later on.

I think the brakes were undersized for the truck.
