At the risk of offending any one, I have never been impressed by Midas or most any other franchise shop. Under trained, under experienced, commission based maintenance sales, etc. In general, I do not recommend turning brake rotors. Braking turns kinetic energy (moving energy) into thermal energy (heat). The heat needs to be absorbed and dissipated. This is one reason there is a minimum thickness on rotors and drums. You have to have enough steel mass to absorb the heat energy during the stop and then get it cooled off before the next stop. Also, for the cost of turning etc, new rotors a usually worth the money, especially if you are planning on keeping a car for a while.

Good luck!
