Technical Description and Specifications

This disc brake rotor features a vented design with straight vanes that promote efficient airflow to reduce heat and prevent brake fade. The smooth surface finish ensures even pad contact and consistent braking response. With a nominal thickness of 0.709 inches (18 mm) and a discard thickness of 0.669 inches (17 mm), this rotor meets the necessary wear limits for safe operation. The overall height of 1.496 inches (38 mm) and an outside diameter of 9.213 inches (234 mm) align with Toyota Corolla factory specifications. The rotor mounts behind the hub using four mounting bolt holes spaced on an 87 mm bolt circle diameter, each hole measuring 10.7 mm in diameter. This rotor does not include an ABS tone ring or bearings.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor thickness below manufacturer discard limits
• Resolving uneven brake pad wear due to rotor surface issues
• Improving braking performance on Toyota Corolla models with OEM fitment
• Eliminating noise or vibration related to damaged rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of rust or debris before installation. Verify the rotor thickness with a micrometer to confirm it meets minimum specifications. Use proper torque settings on mounting bolts to avoid rotor warping. Since this rotor mounts behind the hub, confirm correct alignment during installation. This rotor does not include bearings or an ABS tone ring, so reuse existing components if applicable.
