Installed my Stoptech rear slotted/drilled rear rotors yesterday. there is an intermittent scrapping/rubbing sound coming from the left side. I can especially hear it when driving with the window down and close to the center island or in an alley.
Is it because the pads need to wear to the new rotor, I have 8300 miles on the old ones, or is it possible the rotor is warped or bent?? the right side does it slightly but not nearly as bad. When I installed the fronts I never had this issue, there was only about 3000 miles on the car though. Any thoughts, suggestions appreciated
