Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup
• Uneven pad wear due to poor rotor surface design
• Corrosion and rust on rotor hats and braking surfaces
• Reduced braking performance in wet conditions
• Vibration or noise from warped or damaged rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22.0 mm before installation. The rotor does not include bearings or an ABS tone ring, so verify compatibility with your vehicle’s existing components. Use proper torque specifications for the 5 lug bolts on the 100 mm bolt circle. The coated hat finish helps prevent corrosion, but it is recommended to clean the rotor surface before installation to remove any protective oils.
