Hi- 2002 Insight - recent tire rotation done. Otherwise no recent unusual events. Can anyone help me figure out what happened this AM? Front right wheel was smoking- very hot to the touch. I made it to destination but the car dropped cast iron fragments in the parking lot. Photos attached of busted part and wheel. Can someone please tell me what that part is and if the car is driveable? I'm looking for a repair shop within a mile of where I left the car. Sorry for my ignorance but I tried to look up brake/wheel images and can't find anything resembling this part. Any help much appreciated. Thank you.
