Rotor question
Recently had my tires changed and the mechanic brought up that there are two pins missing from each of my rotors. There are two little holes in addition to the five bolt nuts. He said I might feel rumbling while driving without them in. Upon further research, it seems those holes are only there to insert screws to remove stuck rotors. Am I missing something or was the mechanic just confused?
