^^ That is true.
But also consider the cost, which will probably vary a lot. Some shops around me charge $40+ to do it.

It's often not much more money to get new rotors.Then you dont have to worry about taking your brakes apart, driving another vehicle to a shop to have the rotors turned and hope the trainee tech does a decent job (doesn't turn them too fast or use dull teeth). For how often we need to change brakes on vehicles these days, I'm a fan of spending $80-$100 for a good set of rotors and slapping everything on in a matter of 30 minutes and calling it a day
