This is typical mounting on most cars. If your rotors are warped (ie: Brake Pedal pulsing and/or your ride is pulling to a direction when brakes are applied) it is better to buy new rotors for $35-45 each as the warp is "set" into the metal and will return quickly....WARPED ROTORS ARE TRASH and turning them will only temporarily remedy the problem. Grease the backs of the pads where they contact the caliper piston to avoid rattling. Alll rotors should be cross hatch sanded on a brake lathe prior to installing pads even if the rotors are new.
