Technical Specifications and Features

This disc brake rotor is vented to facilitate better heat dissipation during braking, reducing the risk of brake fade under heavy use. The rotor’s nominal thickness of 0.787 inches (20.0 mm) ensures structural strength, while the discard thickness of 0.724 inches (18.4 mm) indicates the minimum safe thickness before replacement is necessary. The overall height measures 3.445 inches (87.5 mm), and the rotor features five mounting bolt holes arranged on a 5.5-inch (139.7 mm) bolt circle diameter, compatible with Kia Sorento mounting specifications. The smooth surface type promotes even brake pad wear and consistent braking response.

Applications and Problem Solving

• Replacement for worn or warped rotors on Kia Sorento models
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Improves heat management to reduce brake fade during extended braking
• Restores proper rotor thickness for safe braking performance
• Prevents corrosion-related rotor degradation with Gray Armor-Plate coating

Installation Notes and Tips

Ensure the rotor mounting surface and hub are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 0.724 inches (18.4 mm) to maintain safety standards. Use the correct torque specifications for the five mounting bolts on the 5.5-inch bolt circle diameter. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle’s ABS system.
