Technical Description and Specifications

This Centric disc brake rotor features a vented design with straight vanes that facilitate effective heat dissipation during braking. The rotor’s overall height measures 2.567 inches (65.2 mm), ensuring proper alignment with the brake caliper assembly. The nominal thickness of 0.874 inches (22.2 mm) and discard thickness of 0.811 inches (20.6 mm) provide clear service limits for safe rotor replacement. The floating disc mounting style allows for slight movement to reduce stress and improve braking smoothness. With five lug holes sized at 0.555 inches (14.1 mm) diameter and a 4.5 inch (114.3 mm) bolt circle diameter, this rotor fits securely on the Ford Aerostar hub assembly.

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 during extended use
• Restoring proper rotor surface for consistent brake pad contact
• Ensuring correct fitment for Ford Aerostar brake system maintenance

Installation Notes and Tips

Before installation, verify rotor dimensions against vehicle specifications to ensure compatibility. Clean the rotor surface with brake cleaner to remove any protective coatings or contaminants. Use proper torque specifications on lug nuts to avoid rotor warping. Since this rotor does not include bearings or an ABS tone ring, reuse existing components or source separately as needed. Inspect brake pads and calipers during installation for optimal braking performance.
