    Are they warped?
    Are they grooved?
    Are they below minimum thickness?
    Are they dished?

    If the answer to any of those questions is yes, feel free to replace them.
    Granted warped rotors can be straightened. . . . . .

    I'd have to have a really badly warped rotor to replace it. Supposedly, warping is something that can happen really easily on a wet ride. Since I live in the Pacific Northwet, that's pretty frequent.

    Compare the thickness of the braking track to the thickness of the rotor arms. If it looks excessively different, you might consider replacing them.

    Re: When to replace disc?

    Often the rotor will have a min thickness specified on it. You must use calipers or a micrometer. I think my formula rotors are min 1.7mm.
