I have replaced brakes, rotors, calipers and hub bearings on my Cherokee. When i go to stop it still sounds like i have a metal to metal grinding noise. Any ideas?

I too had a 00 XJ, went replace the brakes, and found that the store gave me the wrong rotors! THere are two styles, if you hear grinding, remove the wheel and look to see whats making contact.

Thanks for the advice. I will look into this.
