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

Detailed Product Description

The DuraGo BR31348-01 disc brake rotor is crafted from full cast iron, providing a robust and heat-resistant braking surface essential for maintaining performance under demanding conditions. Its vented design enhances airflow, helping to dissipate heat more effectively than solid rotors, which reduces the risk of brake fade during extended use. The rotor features a drum-in-hat construction, integrating a parking brake drum within the rotor hat, making it compatible with vehicles equipped with drum parking brakes.

With a rust-resistant coating applied to the rotor surface, this part helps prevent corrosion and extends the rotor's service life, especially in environments prone to moisture and road salt. The non-directional brake surface allows for flexible installation without concern for rotor orientation. The rotor's precise dimensions, including a 12.13-inch outside diameter and 5 mounting bolt holes spaced on a 114.3 mm circle, ensure proper fitment on compatible Infiniti and Nissan models.

Compatible Vehicles and Applications

• Infiniti FX35, FX37, FX45
• Infiniti JX35, M35h, M37, M56
• Infiniti Murano, Q50, Q60, Q70, Q70L
• Infiniti QX60, QX70
• Nissan Pathfinder, Quest

This rotor is designed specifically for these models, providing a direct replacement that meets factory specifications.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive brake noise due to worn or damaged rotors
• Reduced braking efficiency from corroded or pitted rotor surfaces
• Brake fade from insufficient heat dissipation
• Parking brake malfunction related to drum-in-hat rotor wear

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 0.55 inches (14 mm) to maintain safe braking performance. Use proper torque specifications for the 5 mounting bolts on the 114.3 mm bolt circle. Since this rotor is non-directional, it can be installed on either side without concern for rotation direction. Check compatibility with your vehicle’s ABS system, as this rotor does not include an ABS tone ring.

Quality Assurance and Warranty

DuraGo manufactures this rotor to meet or exceed OEM standards for fit, form, and function. The cast iron construction and rust-resistant coating contribute to long service life and consistent braking performance. Warranty details should be confirmed with the point of purchase or manufacturer documentation.
