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 noise issues from uneven rotor surfaces
• Improving heat dissipation to prevent brake fade in heavy-duty use
• Ensuring proper fitment for Ford E-Transit and Transit-150/250/350 series vehicles

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness with a micrometer to confirm it meets nominal specifications. Use proper torque settings on the 5 lug bolts with 10 mm diameter threads and 1.5 mm pitch to secure the rotor. Since this rotor does not include bearings or an ABS tone ring, confirm compatibility with your vehicle’s braking system. Follow manufacturer guidelines for brake pad replacement and bedding procedures after installation.
