Product Details and Specifications

This disc brake rotor features a vented design with straight vanes to enhance airflow and heat dissipation, reducing the risk of brake fade during extended use. The rotor’s nominal thickness of 1.024 inches (26.000 mm) and discard thickness of 0.965 inches (24.500 mm) provide clear service limits for maintenance. Its overall height of 2.602 inches (66.100 mm) and outside diameter of 11.260 inches (286.000 mm) ensure proper fitment on compatible vehicles. The floating disc mounting style and 5 lug holes with a diameter of 0.630 inches (16.000 mm) support secure installation. This rotor does not include an ABS tone ring or bearings, so those components must be sourced separately if required.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Resolving excessive brake noise or vibration linked to rotor surface issues
• Upgrading to a vented rotor for improved heat management in daily driving
• Ensuring proper fitment on Ford B3000, B4000, Explorer, Ranger, Mazda, and Mercury Mountaineer models

Installation Notes and Tips

• Verify rotor thickness before installation to ensure it meets minimum discard thickness
• Clean rotor surface and hub mounting area to prevent uneven wear or noise
