Detailed Description

DuraGo BR31424 is a rear brake rotor engineered for vehicles that use a drum-in-hat setup, where the parking brake mechanism is integrated into the rotor hat area. Its solid cast iron design supports stable braking characteristics, while the non-directional surface simplifies rotor orientation during service. This part number, BR31424, is listed for rear fitments on 2005-2020 Hyundai Sonata, 2010-2017 Hyundai Azera, 2015-2017 Hyundai Tucson, 2011-2020 Kia Optima, and 2014-2016 Kia Cadenza applications, including select manual parking brake configurations.

This part cross-references Raybestos Brakes (e.g., 980420, 980902) for the same application.

What It Helps Address

• Rear brake pulsation from worn or uneven rotor surfaces
• Reduced braking consistency caused by rotor wear
• Noise related to rotor surface condition
• Parking brake service needs on drum-in-hat rear brake systems
• Replacement needs for OE-style rear rotor dimensions

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and center bore before installation. This rotor is for rear applications only and is not vented. Confirm whether your vehicle uses a manual parking brake configuration where noted, especially on Hyundai Sonata, Kia Optima, Kia Cadenza, and Hyundai Tucson applications. Clean the hub mounting surface before installing the rotor to help maintain proper runout and braking feel.
