Technical Description and Specifications

This disc brake rotor is made from cast iron, a material known for its strength and heat resistance, which is critical for braking components. The vented design allows air to flow between the rotor surfaces, reducing heat buildup and minimizing the risk of brake fade during extended use. The rotor’s nominal thickness of 1.299 inches ensures structural integrity, while the discard thickness of 1.181 inches indicates when replacement is necessary to maintain safe braking performance. The smooth surface type provides even contact with brake pads, promoting consistent stopping power. With six mounting bolt holes arranged on a 5.197 inch bolt circle diameter, this rotor fits securely on the hub assembly of compatible Ford Transit models.

Compatible Vehicles and Applications

• Ford Transit-150
• Ford Transit-250
• Ford Transit-350
• Ford Transit-350 HD

This rotor is designed to address common braking issues such as uneven rotor wear, overheating, and reduced stopping power, which can occur in commercial vans subjected to heavy loads and frequent stops.

Installation Notes and Tips

• Ensure the rotor thickness is above the discard thickness before installation
• Clean the rotor surface to remove any protective coatings or debris
• Check compatibility with the vehicle’s mounting bolt pattern and thread pitch
• Torque mounting bolts to manufacturer specifications to avoid warping
• Inspect brake pads and replace if worn to ensure optimal rotor performance
