Detailed Product Description

The DuraGo BR31158 rotor is a full cast iron disc brake rotor designed specifically for front brake applications on Nissan Frontier, Pathfinder, Xterra, and INFINITI QX4 vehicles. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent brake performance. The rotor measures 11.12 inches in outside diameter and features six mounting bolt holes with a 4.88-inch bolt circle diameter, compatible with M10 x 1.25 bolts. The nominal thickness of 1.1 inches ensures structural integrity, while the discard thickness of 1.02 inches indicates when replacement is necessary to maintain safe braking. This rotor does not include a rust-resistant coating or ABS tone ring, and it features a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Compatible with Nissan Frontier front brake systems
• Fits Nissan Pathfinder front brakes
• Suitable for Nissan Xterra front brake replacement
• Designed for INFINITI QX4 front brake rotor applications

Common Issues Addressed by This Rotor

• Brake pulsation caused by warped rotors
• Reduced braking efficiency due to worn rotor thickness
• Overheating and brake fade from inadequate heat dissipation
• Noise and vibration from uneven rotor surfaces
• Corrosion-related rotor damage (note: no rust-resistant coating included)

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (1.02 inches) before installation
• Clean mounting surfaces to prevent uneven rotor seating
• Torque mounting bolts to manufacturer specifications (M10 x 1.25 bolt size)
• Check brake pads for wear and replace if necessary during rotor installation
• Verify rotor compatibility with vehicle ABS system as this rotor does not include an ABS tone ring

Quality Assurance and Warranty

DuraGo disc brake rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. While this product does not include a rust-resistant coating, the full cast iron construction provides reliable durability under normal operating conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
