Detailed Product Description

The DuraGo BR31318 disc brake rotor is engineered with a full cast solid construction, ensuring structural integrity and consistent braking under normal driving conditions. Its cast iron material offers effective heat dissipation to reduce brake fade during extended use. The rotor features a drum-in-hat design, integrating a drum brake surface within the rotor hat area, which is compatible with the rear braking system of Acura MDX and Honda Pilot vehicles. This rotor is non-directional and does not include cross-drilled or slotted surfaces, making it suitable for standard replacement needs without altering brake system dynamics.

Compatible Vehicles and Applications

This rotor is compatible with the following vehicles:

• Acura MDX (rear disc brake application)
• Honda Pilot (rear disc brake application)

Use the DuraGo BR31318 rotor when replacing worn or damaged rear rotors on these models to maintain proper braking performance and safety.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear below discard thickness limits
• Uneven braking or noise due to rotor surface damage
• Reduced braking efficiency from heat-related rotor degradation
• Corrosion or rust compromising rotor integrity (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

When installing the DuraGo BR31318 rotor, ensure the mounting surface is clean and free of debris. Verify the rotor thickness is within nominal specifications (0.44 inches) and above discard thickness (0.37 inches) before installation. Use proper torque specifications for the 5 mounting bolts (12.9 mm diameter) to avoid rotor distortion. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.

Quality Assurance and Warranty

DuraGo manufactures the BR31318 rotor to meet or exceed OEM standards for fit, form, and function. The cast iron construction and full cast design provide durability under normal operating conditions. While this rotor does not feature a rust-resistant coating, proper maintenance can help extend its service life. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
