I recently ordered a Powerstop pad and rotor kit for my rear brakes and gave them to my mechanic to install. There were two kits available: one for trucks with rotors greater than 1" thick and one for trucks with rotors less than i" thick. I bought the latter kit. When I went to pick up the truck, the mechanic told me the pads were too small, and he had ordered and installed the correct ones from a local parts wholesaler. I asked him how the rotors were, and he said they fit fine. I am now concerned that I bought the wrong kit and that the rotors "fit" but are actually too narrow. What would be the downside of using these rotors? Should I get the correct ones and replace them? Could they possibly be the correct ones? The overall braking is much better than before I dropped the truck off.
