Detailed Product Description

The DuraGo BR31248 is a vented disc brake rotor specifically designed for Acura CL vehicles, providing effective heat dissipation through its full cast iron construction. The rotor’s nominal thickness of 0.91 inches (23 mm) ensures durability and longevity, while the discard thickness of 0.83 inches (21 mm) indicates when replacement is necessary to maintain safe braking performance. With an outside diameter of 11.1 inches (282 mm) and a mounting bolt pattern of 4 holes on a 4.5 inch (114.3 mm) circle, this rotor fits precisely on compatible Acura CL models. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This conventional rotor does not include an ABS tone ring and features no rust-resistant coating, so proper maintenance is recommended to prevent corrosion over time.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Restores braking efficiency lost due to rotor thinning or scoring
• Addresses noise issues related to uneven rotor surfaces
• Improves heat management to reduce brake fade during extended use
• Compatible upgrade for Acura CL models requiring vented rotors

Installation Notes and Tips

When installing the DuraGo BR31248 rotor on Acura CL vehicles, ensure the mounting surface is clean and free of debris to prevent rotor misalignment. Since this rotor is non-directional, it can be installed on either side without affecting performance. Check the rotor thickness before installation to confirm it meets or exceeds the discard thickness of 0.83 inches (21 mm). Proper torque specifications should be followed for the 4 mounting bolts to ensure secure fitment. Because this rotor lacks a rust-resistant coating, applying a light anti-corrosion treatment on exposed surfaces can help extend service life.

Quality Assurance and Warranty

DuraGo manufactures the BR31248 rotor to meet or exceed OEM specifications for Acura CL vehicles. The cast iron material and vented design contribute to consistent braking performance and durability. While no specific rust-resistant coating is applied, the rotor’s construction supports reliable operation under normal driving conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
