This rotor features a drum-in-hat design, integrating the parking brake drum within the rotor itself, which is compatible with specific Hyundai and Kia models including the Azera, Cadenza, Optima, Sonata, and Tucson. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

This disc brake rotor is compatible with the following makes and models:

• Hyundai Azera
• Hyundai Sonata
• Hyundai Tucson
• Kia Cadenza
• Kia Optima

It is designed to replace worn or damaged rotors, restoring braking efficiency and safety.

Common Issues Addressed by This Rotor

• Brake pulsation caused by warped rotors
• Reduced braking performance due to worn rotor thickness
• Noise and vibration from uneven rotor surfaces
• Corrosion-related rotor damage (note: this rotor does not have rust-resistant coating)
• Parking brake malfunction related to drum-in-hat rotor wear

Installation Notes and Tips

When installing the DuraGo BR31424 rotor, ensure the mounting surface is clean and free of debris. Verify the rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 0.39 inches (10 mm). Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. Proper torque specifications should be followed for the 5 mounting bolts with a 0.49 inch (12.4 mm) diameter. The non-directional design allows installation on either side without concern for rotor orientation.
