Technical Details and Construction

The DuraGo BR901942-01 rotor is made from cast iron, a material known for its excellent heat dissipation and wear resistance, which helps maintain braking efficiency under demanding conditions. This rotor features a full cast construction, providing structural integrity and reducing the risk of warping. The solid rotor design is non-vented, suitable for applications where vented rotors are not required. A rust-resistant coating is applied to the surface to protect against corrosion, helping to extend the rotor's service life.

With an outside diameter of 11.81 inches (300 mm) and a nominal thickness of 0.39 inches (10 mm), this rotor meets OEM specifications for the Hyundai Kona Electric, Kia Sportage, and Tucson. The mounting bolt pattern includes 5 holes with a 4.5 inch (114.3 mm) bolt circle diameter, ensuring proper fitment. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Hyundai Kona Electric
• Kia Sportage
• Kia Tucson

This rotor is designed for use in conventional disc brake systems on the front or rear axle, depending on vehicle specifications. It is suitable for drivers seeking a reliable replacement rotor that meets factory dimensions and performance standards.

Common Issues Addressed by This Rotor

• Brake pulsation caused by warped rotors
• Reduced braking efficiency due to worn rotor thickness
• 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 surface is clean and free of debris before installation. Verify the rotor thickness is within manufacturer specifications, replacing if below the discard thickness of 0.31 inches (8 mm). Use proper torque settings on mounting bolts to avoid rotor distortion. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.
