This Detroit Axle brake kit is new and includes disc brake rotors and ceramic brake pads for rear and disc brake rotors for the front. It's designed for 2011-2016 Kia Optima and 2011-2015 Hyundai Sonata models. Features 11.81-inch front and 11.18-inch rear rotors, which are silver zinc-dichromate plated. I installed the front brake pads on my vehicle and then my car was totaled in an accident.
