Detailed Product Description

The DuraGo BR31339-01 disc brake rotor is constructed from cast iron, a material known for its excellent heat dissipation and durability under braking stress. This rotor features a full cast design, which provides structural strength and helps maintain consistent braking performance over time. The rust-resistant coating protects the rotor surface from corrosion, which is especially beneficial in humid or wet environments.

Designed as a solid rotor with a non-directional brake surface, it ensures even pad wear and smooth braking without the need to align the rotor in a specific direction. The drum-in-hat construction integrates a parking brake drum within the rotor, making it compatible with vehicles equipped with drum parking brakes. With five mounting bolt holes and precise dimensions, this rotor fits securely on compatible Hyundai and Kia models.

Compatible Vehicles and Applications

• Hyundai Sonata (various years)
• Hyundai Tucson
• Kia Optima
• Kia Sportage
• Hyundai Magentis
• Kia XG300 and XG350

This rotor is ideal for replacing worn or damaged rotors on these vehicles, restoring braking efficiency and safety.

Common Issues Addressed by This Rotor

• Brake pulsation caused by warped rotors
• Reduced braking performance due to rotor wear
• Corrosion and rust buildup on rotor surfaces
• Uneven brake pad wear from damaged rotors
• Noise and vibration during braking

Installation Notes and Tips

Ensure the rotor is installed on a clean, debris-free hub surface to prevent runout. Verify the rotor thickness before installation; replace if below the discard thickness of 0.33 inches (8.4 mm). Use proper torque specifications for the five mounting bolts to secure the rotor. Since this rotor does not include an ABS tone ring, confirm compatibility with the vehicle’s ABS system. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.
