Thanks. I just checked the codes yesterday again after my wiring harness problem. No code for the brakes. Didn't show up the last time I got a code for a dirty air cleaner.

I don't remember a sensor in or on the hub held by 2 allen screws though. Does it have to line up with anything on the rotors or calipers. I imagine I just slid the rotors on. I don't recall ever taking the hubs off though.
