Several reasons: fewer comebacks if the rotor or drum was out of true, it
is a high margin operation, and after a couple of brake jobs you get to

lathes never get their settings checked, and they always get abused. It
is not uncommon for the turning operation to introduce its own
out-of-round or out-of-square. And the more meat, the better (less
distortion and handle overheating better). So don't kneejerk getting 'em
