Amazingly, here in the Chicagoland area and collar counties with millions of cars (no exaggeration) no shops will cut drums or rotors anymore. Some claim labor costs can't compete with cheap imports, others say liability insurance issues. But one old and now retired machinist hit it on the head in my mind. The near total lack of do-it-yourselfers resulted in hardly any cylinder head work of yore let alone engine boring, honing, etc.
Now brake/oil change/muffler shops in some cases still do limited brake machining but even here it's more cost-effective to buy new parts. In addition, he said a lack of qualified machinists, older fellows like himself, further hurt the old-school auto parts shops that were steadily replaced by big chains. 'Course we all know the big chain parts stores don't and never did offer said work and even older, long-established NAPA outlets here (many that used to be independent mom & pop owned) sold off the machinery and no longer cut brakes. Sad but true!
