Technical Specifications and Features

This disc brake rotor measures 10.858 inches in outside diameter and has an overall height of 1.858 inches (47.2 mm). The vented rotor design allows air to flow between the rotor surfaces, reducing heat buildup during braking. The nominal thickness of 1.031 inches (26.2 mm) ensures structural integrity, while the discard thickness of 0.961 inches (24.4 mm) indicates the minimum safe thickness before replacement is necessary. The rotor mounts with five bolts on a 4.5 inch (114.3 mm) bolt circle diameter, and the center hole diameter is 2.717 inches (69.0 mm). The smooth surface type promotes even brake pad wear and consistent braking performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Hyundai Santa Fe models
• Addresses brake pulsation caused by uneven rotor surfaces
• Improves heat dissipation to reduce brake fade during extended use
• Restores proper rotor thickness for safe braking performance
• Eliminates noise and vibration related to damaged rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the mounting bolt hole pattern and center hole diameter match the vehicle specifications. Use a torque wrench to tighten bolts to manufacturer-recommended specifications. Since this rotor does not include an ABS tone ring, confirm compatibility with the vehicle’s ABS system. Inspect brake pads for wear and replace if necessary to maintain optimal braking performance.
