• Overall height of 1.85 inches (47 mm) ensuring proper fitment
• Outside diameter of 11.1 inches (282 mm) compatible with specified vehicles
• Five mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Technical Details and Construction

The DuraGo BR31257 rotor is constructed from full cast iron, providing a solid and reliable braking surface. Its vented design allows air to flow between the rotor faces, reducing heat buildup and minimizing brake fade during extended use. The rotor measures 11.1 inches in outside diameter and features five mounting bolt holes spaced on a 114.3 mm bolt circle diameter, ensuring compatibility with Acura and Honda models such as the Accord, Civic, CSX, Element, Fit, and ILX. The nominal thickness of 0.91 inches (23 mm) and discard thickness of 0.83 inches (21 mm) help maintain optimal braking performance and safety standards.

Compatible Vehicles and Applications

This disc brake rotor is compatible with the following makes and models:

• Acura Accord, CSX, ILX
• Honda Accord, Civic, Element, Fit

It is designed for use in conventional braking systems without ABS tone rings and fits vehicles requiring a vented, non-directional rotor with five mounting bolts.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Reduced braking efficiency due to worn or thin rotors
• Overheating and brake fade from insufficient heat dissipation
• Uneven brake pad wear linked to rotor surface irregularities
• Noise and pulsation caused by damaged or scored rotors

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean rotor surface to remove any protective coatings or debris
• Check mounting bolt hole alignment and torque bolts to manufacturer specifications
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Perform a bed-in procedure after installation to maximize braking efficiency
