Getting rotors turned?
 

Does anyone know of a shop that will turn a set of rotors...in Ocala, FL?

Nope, Do not get your rotors turned. Just replace them.

Interesting response. Why should I not get the rotors turned? They've not been turned prior...and typically I've had rotors turned once before replacement.

I'd say most shops that have a lathe can turn your rotors, just call around. Turning once is acceptable if you want to save a few bucks, but its obviously not optimal for performance.

MB rotors are not intended to be resurfaced. If there is excessive runout they should be replaced. If under min. thinkness they should be replaced. Otherwise just replace the friction material. They tend to get a very bad pattern in them when you attempt to machine them due to the alloy in the rotor. The end up looking like a record and ruining the tips on the brake lathe.

A while back, somebody posted a tech article about turned rotors vs new. If I remember correctly, the tech data show that turned rotors increased stopping distance by as much as 60%. The spiral grooves that result from turning on a brake lathe cause the brake pads to "skip". In the past, I used to get rotors turned once before replacing--now I just replace with new.

I wouldn't turn Mercedes rotors, they just don't have enough meat on them. The minumum thickness stamped into the rotor is a absolute wear limit, not what you can safely turn the rotors down to.

I know of one case where the caliper piston came out of its bore and the driver had an accident due to the immediate lose of brake pressure. The driver sued and won against the shop that did the work. Testimony given at the trial by a factory trained technician included the fact that MB rotors are not to be turned and no specification is given for turning rotors in the dealer technical data books, only the wear limit.

Mercedes spec rotors are not designed to be turned. They are thin, by design, and don't have enough material to lathe off. That is not to say they can't be turned, but you will introduce a whole new set of problems if you do. Just buy new ones. They are cheap and you have the priceless peace of mind that you did something to spec.
