Detailed Product Description

The DuraGo BR31384 disc brake rotor features a full cast iron construction, which is standard for effective heat absorption and dissipation during braking. Its vented design allows air to flow between the rotor surfaces, reducing the risk of brake fade under heavy use. With an outside diameter of 11.02 inches and a nominal thickness of 1.02 inches, this rotor maintains structural integrity and performance throughout its service life. The rotor is designed with four mounting bolt holes, ensuring secure attachment to the hub assembly on compatible Hyundai Magentis, Sonata, and Kia Optima models. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

This rotor is specifically compatible with the following vehicles:

• Hyundai Magentis
• Hyundai Sonata
• Kia Optima

It is intended for use in front or rear disc brake systems where a vented, conventional rotor is required. The DuraGo BR31384 is suitable for drivers seeking a direct replacement rotor that meets factory specifications.

Common Issues Addressed by DuraGo BR31384 Rotor

• Brake pulsation caused by warped or uneven rotors
• Reduced braking efficiency due to worn or thin rotors
