The boxes for the front and back are exactly the same.So did Rockauto send you the wrong parts or did you order RR & RL rotors instead of FR & FL rotors?
I think I'm ok since those lines were already there pre install. I stopped driving the second i heard the noise. I checked the pads and the brake and everything seemed OK.Does this mean he has to get new rotors? All those lines don't look good.
