• Vented rotor design to improve cooling
• Drum-in-hat construction for integrated parking brake function
• Non-directional brake surface for versatile installation
• Five mounting bolt holes with 114.3 mm bolt circle diameter
• Outside diameter of 308 mm (12.13 inches) and overall height of 62 mm (2.44 inches)
• Nominal thickness of 16 mm (0.63 inches) with discard thickness at 14 mm (0.55 inches)

Detailed Product Description

The DuraGo BR31348 disc brake rotor is constructed from full cast iron, providing a robust and heat-resistant braking surface suitable for a range of Infiniti and Nissan vehicles. Its vented design enhances airflow to reduce heat buildup during braking, which helps maintain consistent stopping power and rotor longevity. The drum-in-hat construction integrates a parking brake drum within the rotor, eliminating the need for a separate drum and simplifying the braking system. This rotor features a non-directional surface, allowing for flexible installation without concern for rotor orientation. With five mounting bolt holes spaced on a 114.3 mm (4.5 inch) bolt circle diameter, it fits securely on compatible hubs. The rotor’s dimensions, including a 308 mm outside diameter and 62 mm overall height, align with factory specifications for models such as the Infiniti FX35, Q70, and Nissan Murano.
