Technical Specifications and Design Features

This DuraGo disc brake rotor measures 13.31 inches (338 mm) in outside diameter with an overall height of 2.66 inches (67.5 mm). The nominal thickness is 1.1 inches (28 mm), with a discard thickness of 1.02 inches (26 mm), indicating when replacement is necessary. The rotor features a vented design to facilitate better heat dissipation during braking, reducing the risk of brake fade. It includes six mounting bolt holes with a bolt circle diameter of 5.5 inches (139.7 mm) and a center hole diameter of 4.26 inches (108.1 mm). The rotor surface is non-directional and conventional, without cross-drilling or slotting, providing consistent braking performance under normal driving conditions.

Compatible Vehicles and Applications

The DuraGo BR31326-01 disc brake rotor is specifically compatible with the following vehicles:

• Lexus 4Runner
• Toyota GX470

This rotor is designed to replace worn or damaged rotors on these models, restoring braking efficiency and safety.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear leading to reduced braking performance
• Corrosion and rust buildup on rotor surfaces
• Overheating and brake fade from insufficient heat dissipation
• Uneven rotor thickness causing brake noise or pulsation

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 1.02 inches (26 mm) to maintain safety standards. Use the six mounting bolt holes to securely fasten the rotor, matching the bolt circle diameter of 5.5 inches (139.7 mm). This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle’s ABS system. Proper torque specifications should be followed during installation to avoid rotor damage.
