• Outside diameter of 12.6 inches (320 mm) suitable for Mazda CX-9 brake systems
• Five mounting bolt holes with a bolt circle diameter of 4.5 inches (114.3 mm)
• Non-directional brake surface for versatile installation
• Conventional rotor type without cross-drilled or slotted features

Detailed Product Description

The DuraGo BR900354 disc brake rotor is constructed from full cast iron, providing a balance of durability and effective heat management. Its vented design allows air to circulate between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade under normal driving conditions. With a nominal thickness of 1.1 inches (28 mm) and a discard thickness of 1.02 inches (26 mm), this rotor maintains structural integrity throughout its service life. The rotor measures 12.6 inches (320 mm) in outside diameter and features five mounting bolt holes arranged on a 4.5-inch (114.3 mm) bolt circle, ensuring compatibility with the Mazda CX-9 brake assembly. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

This disc brake rotor is compatible with Mazda CX-9 models requiring a 320 mm vented rotor with five mounting bolts. It is designed for use in conventional brake systems without ABS tone rings or specialized rotor surface treatments such as slots or cross-drilling.

• Restores braking performance on Mazda CX-9 vehicles
• Replaces worn or warped rotors causing brake pulsation
• Addresses rotor thickness below manufacturer discard limits
• Improves heat dissipation to reduce brake fade
• Eliminates noise and vibration related to rotor surface wear

Installation Notes and Tips

When installing the DuraGo BR900354 rotor, ensure the rotor surface is clean and free of any protective coatings or debris. Verify that the rotor thickness meets or exceeds the nominal thickness specifications before installation. Use proper torque specifications for the mounting bolts to avoid rotor warping. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for orientation. It is recommended to inspect brake pads and other braking components during rotor replacement to ensure optimal system performance.

Quality Assurance and Warranty

DuraGo manufactures the BR900354 rotor to meet or exceed OEM standards for fit, form, and function. The full cast iron construction and vented design contribute to consistent braking performance and durability. While this product does not include a rust-resistant coating, proper maintenance and regular inspections can help extend rotor life. Warranty coverage details should be confirmed with the product documentation or supplier.
