My front rotor wobbles a few mm - just enough so that it either squeaks intermittently, or there's too much lever travel - depending on the pad clearance.
I can see truing a really-taco-d rotor with a hammer and/or some educated bending... but this is much more subtle.
Is there a technique?
My kneejerk was application of sufficient heat, followed by sandwiching it between two dead-flat surfaces - probably also heated quite a bit, but I'd guess there is a loss-of-tempering issue lurking there. -- PeteCresswell
