2001 E250 65000mi. Replaced front ABS brakes & rotors, all went well, but now I have a metal to metal scraping sound coming from both front wheels. I have not driven it yet, I had the noise just moving it back & forth in the garage. Could this be the ABS sensor scraping on the rotor, & is there an adjustment for that?? I do not want to drive it til I know what is going on. HELP Tombo
