Applications and Problem Solving

• Replacement for worn or warped rotors on Ford E-150 Econoline and F-350 Super Duty
• Restores braking performance affected by rotor thickness below discard limits
• Addresses brake pulsation caused by uneven rotor surfaces
• Prevents brake noise and vibration due to rotor wear
• Ensures proper fitment for mounting bolt hole specifications on select Ford trucks

Installation Notes and Tips

Before installation, verify rotor thickness to ensure it meets or exceeds the nominal thickness of 1.420 inches. Clean the mounting surface to remove rust or debris for proper rotor seating. Use the correct torque specifications for mounting bolts with a 5.000-inch bolt hole diameter and 127.000 mm bolt circle diameter.
