Technical Description and Specifications

This Centric disc brake rotor features a vented construction with straight vanes to optimize airflow and heat dissipation during braking. The smooth surface finish ensures even pad contact and reduces noise. With a nominal thickness of 0.874 inches (22.2 mm) and a discard thickness of 0.811 inches (20.6 mm), the rotor provides a clear service limit for safe operation. The overall height measures 2.571 inches (65.3 mm), and the rotor mounts using a floating disc mounting style. The 5 lug holes are spaced on a 4.5 inch (114.3 mm) bolt circle diameter, compatible with Ford Aerostar wheel hubs. This rotor does not include ABS tone rings or bearings, so those components must be sourced separately if required.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Aerostar vehicles
• Addresses brake pulsation caused by uneven rotor surfaces
• Restores proper rotor thickness to maintain braking performance
• Improves heat dissipation to reduce brake fade during extended use
• Suitable for routine brake system maintenance and repairs

Installation Notes and Tips

Ensure the rotor surface is clean and free of rust or debris before installation. Verify the rotor thickness is within the specified discard limits to maintain safety. Use proper torque specifications on lug nuts to avoid rotor warping. Since this rotor does not include bearings or ABS tone rings, confirm compatibility and install those components separately if needed. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
