Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor thickness below manufacturer discard limits
• Improving heat dissipation to reduce brake fade on Hyundai Elantra and Tiburon
• Restoring smooth braking performance with OEM-spec rotor dimensions
• Resolving uneven pad wear due to rotor surface irregularities

Installation Notes and Tips

Ensure the rotor mounting surface and hub are clean and free of rust or debris before installation. Verify the rotor thickness is within discard limits before mounting. Use proper torque specifications for the four mounting bolts to secure the rotor behind the hub. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
