Hey my brakes are going and im in need of new ones. I had the duralast ceramic pads and their getting bad. My rotors are also rusted so ill be buying new drilled and slotted ones. I was curious if theres anything more that i'll NEED if i buy 12" rotors for the front and back, and new pads. Can i throw them right on without needing anything else (everything else seems to be fine) ? Thanks.
