Technical Details and Construction

The BR31333 rotor features a full cast iron construction, which is standard for many OEM replacement rotors, providing a balance of strength and heat management. This rotor is solid rather than vented, making it suitable for vehicles that do not require additional cooling features. The drum-in-hat design integrates the parking brake drum within the rotor, compatible with the brake systems on Hyundai Magentis, Kia Optima, and Hyundai Sonata models. The rotor does not include an ABS tone ring and has a non-directional braking surface, allowing for flexible installation orientation.

Compatible Vehicles and Applications

This DuraGo disc brake rotor is compatible with the following vehicles:

• Hyundai Sonata
• Hyundai Magentis
• Kia Optima

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

Common Issues Addressed by This Rotor

• Brake pulsation or vibration due to warped rotors
• Reduced braking performance from worn rotor thickness
• Noise or squealing caused by uneven rotor surfaces
• Overheating issues from deteriorated rotor material
• Parking brake malfunctions related to drum-in-hat rotor wear

Installation Notes and Tips

When installing the DuraGo BR31333 rotor, ensure the rotor surface is clean and free of rust or debris. Verify the rotor thickness is above the discard thickness of 0.33 inches (8.4 mm) before installation. Use proper torque specifications for the 4 mounting bolts with a 0.49 inch (12.5 mm) diameter. Since this rotor is non-directional, it can be installed in either orientation. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
