Detailed Product Description

This disc brake rotor is constructed from full cast material, providing a robust and reliable braking surface. The vented design enhances airflow, helping to reduce heat buildup during braking, which is critical for maintaining consistent stopping power and rotor longevity. With a smooth surface finish, the rotor ensures even pad wear and quiet operation. The precise dimensions, including a 13.58-inch outside diameter and a 4.50-inch mounting bolt hole circle diameter with 5 lug holes, guarantee compatibility with the rear brake assemblies of Ford Explorer, Flex, Taurus, and Lincoln MKS and MKT models. The rotor’s nominal thickness of 0.76 inches and discard thickness of 0.69 inches provide clear service limits for maintenance.

Common Applications and Problem Solving

• Replacement for worn or warped rear brake rotors on compatible Ford and Lincoln vehicles
• Improves braking performance and heat dissipation in rear disc brake systems
• Addresses issues related to brake fade during extended use
• Restores smooth braking by eliminating rotor surface irregularities
• Supports safe vehicle operation by maintaining proper rotor thickness and structural integrity

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is within the nominal range and above the discard thickness to maintain safety standards. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle’s ABS system. Use proper torque specifications for mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
