Product Details

DFC GEOSPEC rotors are machined to tight tolerances and built to OE specifications using G3000/G11H18 cast iron. Each rotor is inspected for critical dimensions, and vented rotors are balance-checked for stability. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging avoids the need to clean oil from the rotor before installation. The 5000 Advanced pads are formulated for stable friction performance and reduced break-in time, making this kit a practical choice for rear brake service on the Kia Sorento. Part number 4512-21070 is also useful when matching the correct rear brake kit for 2015-2020 Kia Sorento maintenance work.

What This Kit Helps Address

• Rear brake noise from worn pads or fatigued hardware
• Rotor rust and surface corrosion
• Uneven braking feel from worn or out-of-spec components
• Excessive caliper movement caused by aged hardware
• Longer stopping distances due to worn rear brake parts

Installation Notes and Tips

Before installation, confirm rear axle fitment for the 2015-2020 Kia Sorento and verify the part number 4512-21070 against your service order.
