Detailed Description

Centric 320.51040F is a front disc brake rotor engineered for the 2010-2012 Hyundai Santa Fe and 2011-2013 Kia Sorento. The GCX Elemental Protection full coating helps protect the rotor’s non-friction surfaces, while the smooth braking face is intended to work with standard front brake pad service. With a vented, straight-vane design and floating disc mounting, this rotor follows the dimensional requirements listed for the application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Rotor Helps Address

• Front brake pulsation related to worn or uneven rotor surfaces
• Corrosion on exposed rotor areas from road moisture and salt
• Brake noise caused by excessive rotor wear or surface damage
• Reduced braking consistency from rotors below discard thickness
• Fitment issues when replacing the front rotor on a Hyundai Santa Fe or Kia Sorento

Installation Notes and Tips

Verify rotor dimensions, hub fit, and bolt pattern before installation. Clean the hub mounting surface thoroughly to reduce runout concerns, and inspect pads, calipers, and hardware condition during service. For best results, follow the vehicle manufacturer’s brake bedding procedure after installation. Fits 2010-2012 Hyundai Santa Fe, front. Fits 2011-2013 Kia Sorento, front.

Quality Assurance

Centric’s GCX Elemental Protection line focuses on coated rotor surfaces and application-specific sizing for brake service on listed Hyundai and Kia vehicles. Part number 320.51040F is built to the stated dimensions and fitment for the confirmed front applications.
