The friction material compound replicates original equipment coefficient-of-friction characteristics across the full operating temperature range. It delivers stable response during low-speed urban braking and parking operation, and maintains consistent performance during continuous deceleration. The balanced friction coefficient creates smooth pedal feel, supporting stable rear axle braking coordination with the front brake system.
Each pad is fitted with a laminated shim assembly bonded between the backing plate and caliper contact surfaces. The alternating rubber-steel-rubber layers absorb and dissipate high-frequency vibration generated during braking, which reduces brake squeal and groan during daily operation, especially during low-speed braking and parking brake engagement.
The package includes a full set of installation hardware, consisting of stainless steel abutment clips, anti-rattle springs, and anti-corrosion coated mounting components. The clips secure pad position within the caliper bracket to prevent rattling. The retention springs maintain proper pad clearance when brakes are released, reducing residual drag.
All components are machined on 5-axis CNC equipment, with every dimension verified via coordinate measuring machines to ensure proper installation without modification. Production follows ISO 9001 quality management systems, with full batch traceability maintained throughout the supply chain. The components work with both original equipment and aftermarket brake assemblies.
This brake pad set fits the following vehicle models and production years:
Hyundai Sonata: 2013-2022, mid-size sedan
Hyundai Santa Fe DM/CN7, Tucson TL/NX4: 2013-2022
Kia Sorento UM/MP, Sportage QL/QLE, Optima JF/K5: 2013-2022
For unlisted vehicle models, business buyers may provide the VIN to customer support for fitment verification.
Root causes include worn friction material reaching the wear indicator tab, glazed pad surface from repeated braking, damaged anti-squeal shims, and material mismatch between pads and rotors. The noise is more noticeable during low-speed braking or parking brake use. Solution steps: Replace left and right rear brake pad sets at the same time. Apply high-temperature brake grease to backing plates and caliper contact points. Machine or replace rotors if thickness variation over 0.03mm is present. Complete a bedding-in procedure with 8-10 moderate stops from 50 km/h to 20 km/h.
Root causes include friction material worn below the 2mm minimum limit, fluid contamination on pad surfaces, heat fade from heavy use, and uneven wear from seized caliper slide pins. Symptoms include longer pedal travel and uneven rear braking force. Solution steps: Replace all rear pads if thickness is below 3mm. Inspect and lubricate caliper slide pins with silicone grease. Flush and replace brake fluid if contaminated or older than 2 years.
Root causes include uneven material transfer to the rotor surface, rotor warpage from excessive heat, and material incompatibility. Symptoms include rear body vibration during braking and noticeable pedal pulsation at medium speeds. Solution steps: Replace rear brake pads and resurface or replace rear rotors as a set. Clean the hub mounting surface to ensure proper rotor alignment. Torque wheel lug nuts in a star pattern to factory specifications.
This is an aftermarket replacement part manufactured to meet or exceed OEM specifications. It delivers equivalent fit, form, and function compared to the original equipment part.
Cross-reference the OEM part number 58302-3SA20 with your vehicle VIN through an authorized dealer or online fitment checker. The OEM part number is the most reliable reference for accurate part matching.
Standard automotive hand tools are sufficient for most installation procedures. A torque wrench is recommended to ensure all fasteners are tightened to factory specifications.
Warranty applies to manufacturing defects under normal use conditions. Improper installation, competition use, or unauthorized modifications void the warranty.
