The rotor design uses G3000\/G11H18 cast iron and a non-directional finish to support even pad bed-in, quieter operation, and stable braking performance. The coating is applied to help protect the rotor surface from corrosion while keeping the part ready for installation.\u003c\/p\u003e\u003cp\u003eThe pad set is formulated for passenger vehicles and light-duty trucks, with low copper content and friction stability that suits everyday braking demands. This kit is a practical choice for Hyundai Sonata rear brake service, Hyundai Tucson rear brake service, and Kia Cadenza rear brake service where OE-style fit and predictable stopping behavior matter. The part number 4312-03021 is also useful when matching a direct replacement brake kit for these applications.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake noise caused by worn hardware or uneven pad contact.\u003c\/li\u003e\n\u003cli\u003eRust buildup on rotor surfaces.\u003c\/li\u003e\n\u003cli\u003eExcessive brake dust from older pad materials.\u003c\/li\u003e\n\u003cli\u003eUneven or inconsistent braking feel during normal driving.\u003c\/li\u003e\n\u003cli\u003eReduced stopping performance from worn rear brake components.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eFits 2015-2019 Hyundai Sonata, rear; 2016-2017 Hyundai Tucson, rear; and 2014-2016 Kia Cadenza, rear. One fitment note indicates manual parking brake applicability on certain rear rotor applications, so verify the parking brake configuration before installation. The rotors are shipped dry and ready to install, which reduces prep time during brake service.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDFC states that the rotors are machined to tight tolerances, inspected for critical dimensions, and checked for balance on vented designs. The rotors carry a 12-month warranty against defects in material and workmanship. Part number 4312-03021 reflects a complete brake kit built to OE-style form, fit, and function standards.\u003c\/p\u003e","brand":"Dynamic Friction","offers":[{"title":"Default Title","offer_id":53305479397557,"sku":"HBHR-4312-03021","price":108.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_431203021_Fro.jpg?v=1789626231","url":"https:\/\/www.partcatalog.com\/products\/dynamic-friction-4312-03021-disc-brake-kit-rear","provider":"PartCatalog","version":"1.0","type":"link"}
