ABS Troubleshooting February 08, 2010, 12:05:49 AM I upgraded to Bear Claws and (with a little machining) was able to retain the ABS. Until recently it was working great but now my right rear locks up on hard braking with an ABS light. Does anybody know how to troubleshoot the system? So far my searches haven't borne any fruit. I'm thinking wheel sensor but I thought there was a procedure. Any help would be great.
