The kit pairs DFC GEOSPEC coated rotors with DFC 3000 ceramic pads and matching hardware, giving you the core components needed for a complete rear brake service on these applications. The coated rotor surface helps fight corrosion, while the pad formulation is designed for consistent braking performance across a wide temperature range. This part number, 4312-03024, is a practical choice when replacing worn rear brake components on a Kia Optima or Hyundai Sonata.\u003c\/p\u003e\u003cp\u003eDFC GEOSPEC rotors are machined to OE-style tolerances and finished to promote even pad bedding and smoother operation. The 3000 ceramic pads are post-cured and scorched to reduce initial break-in time and support reliable stopping from the first stop. This disc brake kit is also suited to rear brake service where noise control, corrosion resistance, and stable pedal feel matter.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Solve\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake noise caused by worn pads or fatigued hardware\u003c\/li\u003e\n\u003cli\u003eUneven braking from corroded or worn rotor surfaces\u003c\/li\u003e\n\u003cli\u003eExcessive dust buildup from older brake pad material\u003c\/li\u003e\n\u003cli\u003eReduced stopping consistency from heat-related fade\u003c\/li\u003e\n\u003cli\u003eHarshness or vibration during rear brake operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eFits 2016-2020 Kia Optima, rear. Fits 2016-2019 Hyundai Sonata, rear. Some Hyundai Sonata and Kia Optima applications note manual parking brake compatibility or specific front disc size requirements, so verify the exact vehicle configuration before ordering. The rotors are processed dry and ready to install without additional preparation. Part number 4312-03024 should be matched to the vehicle’s rear brake setup before installation.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDFC states that each rotor is inspected to meet OE specifications, and the rotor coating is engineered for durable corrosion resistance. The manufacturer also lists a 12-month warranty against defects in material and workmanship for the rotors in this kit.\u003c\/p\u003e","brand":"Dynamic Friction","offers":[{"title":"Default Title","offer_id":53305479430325,"sku":"HBHR-4312-03024","price":107.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_431203024_Fro.jpg?v=1789626238","url":"https:\/\/www.partcatalog.com\/products\/dynamic-friction-4312-03024-disc-brake-kit-rear","provider":"PartCatalog","version":"1.0","type":"link"}
