The lines are unusual. Do they correlate with the internal fins (assuming the factory rotors are finned)?Can I get a consensus from others? Take a close look at your front and rear rotors and see if they have any of these lines on them going from the hub to the edge of the rotor. Ive been feeling a slight roughness in the brake pedal and I'm wondering if this might be the cause. I'm not looking forward to taking her to the shop for brakes again. Pictures attached show the area of concern.
