Great article to sell stuff. Missing a bunch of facts though. Rotors can make a grind sound due to surface rust from moisture or just plane worn out pads coming in contact .. not just the wear markers.
Also, if you have ‘hat’ style rotors they might be designed to be economically replaced at each pad job. However the hub and rotors combo was never designed to be a throw away. In any case either can be turned so long as the new thickness is not under the federal mandated dimension. The idea of replacing them prior to that dimension is just wasting money.
