Detailed Product Description
The DuraGo BR31236 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 and a discard thickness of 1.02 inches, this rotor meets the specifications required for safe and efficient braking performance on Infiniti Q45 vehicles.
The rotor measures 11.64 inches in outside diameter and features a 5-bolt mounting pattern with a 4.5 inch bolt circle diameter, ensuring proper alignment and fitment. The non-directional brake surface means the rotor can be installed in either orientation without affecting performance. This conventional rotor design is compatible with the braking system of Infiniti Q45 models, providing a direct replacement option for maintenance or repair.
Common Applications and Issues Addressed
- Replacement for worn or warped rotors causing vibration or noise during braking
- Restores braking efficiency when rotor thickness falls below manufacturer discard limits
- Addresses brake fade issues due to overheating in vented rotor design
- Eliminates pulsation or uneven braking caused by rotor surface irregularities
- Ensures proper fitment and compatibility with Infiniti Q45 brake assemblies
Installation Notes and Tips
- Verify rotor thickness before installation to ensure it meets minimum discard thickness
- Clean mounting surfaces to prevent rotor misalignment and ensure secure fit
- Torque mounting bolts to manufacturer specifications to avoid rotor warping
- Inspect brake pads and replace if worn to maintain optimal braking performance
- Perform a test drive to confirm proper brake operation after installation
