Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered around OEM-style rotor specifications using G3000/G11H18 cast iron and tight machining tolerances. The rotors are finished with a non-directional surface to help the pads seat evenly, while the coated surface helps resist corrosion better than conventional paint or zinc finishes. The 5000 Advanced pads are formulated for stable friction, reduced initial break-in, and improved noise and vibration control. This part number, 4502-03112, is a direct front brake service solution for Kia Optima and Hyundai Sonata models listed in the fitment data.

Common Brake Issues This Kit Can Address

• Front brake noise during stopping
• Rotor rust on exposed braking surfaces
• Uneven pad transfer or inconsistent pedal feel
• Brake vibration from worn or out-of-spec rotors
• Extended stopping distance from worn pads

Installation Notes

Compatible With front axle service only. The rotors are shipped dry and ready for installation, which can reduce prep time during brake service. Follow vehicle-specific service procedures, inspect calipers and related wear items before assembly, and complete a proper pad bed-in after installation. For fitment confirmation, use the vehicle year, make, model, and front position exactly as listed for 2011-2016 Kia Optima, 2011-2015 Hyundai Sonata, and 2009-2010 Hyundai Sonata from 12/09.

Quality Assurance

Each rotor is inspected for critical dimensions and balance, and every rotor includes a 12-month warranty against defects in material and workmanship. DFC 5000 Advanced pads are post-cured and scorched to support consistent friction performance from the first stops.
