Product Details

The 4512-21000 brake kit is engineered for rear service on the Hyundai Sonata, Kia K5, and Kia Niro EV. DFC Geospec rotors are cast to G3000/G11H18 specifications, machined to tight tolerances, and inspected for balance and critical dimensions. The 5000 Advanced pads are formulated for stable friction performance and reduced break-in time, while the included hardware is designed to restore proper spring tension and caliper movement during brake service.

This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

Common Brake Service Issues

• Rear brake noise during stops
• Uneven pad wear or rotor wear
• Corrosion on exposed rotor surfaces
• Reduced braking smoothness after worn hardware
• Longer stopping response from aged rear brake components

Installation Notes

Fits 2020-2026 Hyundai Sonata, rear. Fits 2021-2026 Kia K5, rear. Fits 2023-2026 Kia Niro EV, rear. Clean the hub surface before installation, verify rotor seating, and follow the vehicle manufacturer’s torque specifications.
