The GEOSPEC rotor coating helps protect the braking surface from corrosion, while the machined finish and balance inspection support quiet operation and stable stopping performance. The 3000 ceramic pad formulation is designed for passenger vehicles and light-duty trucks, with low dust output and reliable friction across a wide temperature range.\u003c\/p\u003e\u003cp\u003eFor Hyundai Sonata, Kia Optima, Kia Cadenza, and Hyundai Tucson rear brake applications, this kit provides a direct service solution that matches the vehicle-specific fitment listed below. The 4302-03021 kit is also a practical choice when replacing worn rear brake components and restoring braking response, rotor finish, and pad consistency.\u003c\/p\u003e\u003cp\u003eThis part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Solve\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake noise caused by worn pads or uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eReduced stopping consistency from heat-affected friction material\u003c\/li\u003e\n\u003cli\u003eRust buildup on exposed rotor surfaces\u003c\/li\u003e\n\u003cli\u003eExcess brake dust from older pad formulations\u003c\/li\u003e\n\u003cli\u003eVibration or harshness during normal braking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify rear fitment by year, make, model, and notes before ordering.
