Technical Specifications and Features

This vented disc brake rotor features a smooth surface type that supports even pad wear and braking response. The rotor’s nominal thickness of 0.787 inches (20.0 mm) and discard thickness of 0.709 inches (18.0 mm) define the usable rotor life before replacement is necessary. The overall height of 2.370 inches (60.2 mm) and outside diameter of 12.354 inches (313.8 mm) ensure compatibility with the specified vehicle models. The rotor includes five lug holes with a 4.5 inch (114.3 mm) bolt circle diameter and a center hole diameter of 2.717 inches (69.0 mm), matching factory mounting requirements. The rotor’s vented design with straight vanes aids in heat dissipation during braking, reducing the risk of brake fade under normal driving conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Hyundai Equus and Kia K900
• Addresses brake pulsation caused by uneven rotor surfaces
• Improves braking performance by restoring proper rotor thickness
• Reduces noise and vibration associated with damaged rotors
• Maintains safe braking distances by ensuring consistent rotor condition

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness
• Clean rotor surface and hub mounting area to prevent runout and vibration
• Use proper torque specifications on lug nuts to avoid rotor distortion
• Inspect brake pads and replace if worn to optimize rotor performance
• Check for ABS sensor compatibility as this rotor does not include an ABS tone ring
