Detailed Product Description

The DuraGo BR31347 disc brake rotor is constructed from full cast iron, providing a solid and reliable braking surface. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup and helping to maintain braking efficiency under demanding conditions. With a nominal thickness of 0.98 inches (25 mm) and a discard thickness of 0.91 inches (23 mm), this rotor meets the specifications required for safe and effective brake performance. The rotor features a 1.85 inch (47 mm) overall height and an 11.81 inch (300 mm) outside diameter, designed to fit specific Acura and Honda models including the Civic, CR-V, CSX, and RSX. The five mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter ensure secure attachment to the vehicle hub. This rotor does not include an ABS tone ring and is a conventional, non-directional rotor suitable for standard brake systems.

Compatible Vehicles and Applications

• Acura CSX and RSX models requiring a 300 mm vented disc brake rotor
• Honda Civic and CR-V models compatible with a 5-bolt, 4.5 inch bolt circle rotor
• Replacement for worn or damaged rotors to restore braking performance
• Ideal for addressing issues such as brake noise, vibration, or reduced stopping power
• Suitable for routine brake system maintenance and rotor resurfacing replacement

Installation Notes and Tips

When installing the DuraGo BR31347 rotor, ensure the mounting surface is clean and free of debris to promote proper fitment. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness specification of 0.91 inches (23 mm). Use proper torque specifications for the five 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 rotation direction. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.

Quality Assurance and Warranty

DuraGo manufactures the BR31347 rotor to meet industry standards for material quality and dimensional accuracy. The 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 installation will help extend rotor life. Warranty coverage details should be confirmed with the product documentation or supplier.
