This is just me but I bought new rotors from O'Reilly's in 2005 when I bought my car and brakes and it had 164,000 then and now it has 181,000 and I am still riding the same rotors and have changed the rear brakes once since then but it was because they were put in wrong. Now all is good and the rotors were not hurt in any way, just wore the pads down. Front brakes are still good and no shimmy.
Please explain how someone could put front pads in wrong?
