Rotor replacement

All I know is, all of the rotors I have ever replaced the studs popped right out with like 2 pops of an air chisel. IF they were swedged, that would not have happened. I'm not gonna argue one way or the other, but that's my experience. I've never seen KH disc brakes with swedged studs. As I've said many times in the past, that doesn't mean "much".
