Re: A Spec for Turning Brake Drums

All the modern drums I've handled are marked with maximum allowable diameter or some similar expression of limits. Back when I did a bit of brake work I'd want to turn drums that were warped out of round but if they were still true and concentric but with just a few light grooves, we'd leave them as is, slightly shorter lining life was the preferred choice over the alternative of machining the drums.
