Technical Details and Construction

The DuraGo BR31055 rotor is made from cast iron, a material known for its excellent thermal conductivity and wear resistance. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and maintain consistent stopping power. The rotor measures 11.46 inches in diameter and 2.59 inches in overall height, fitting precisely on Toyota 4Runner and T100 models requiring this specification. With six mounting bolt holes spaced on a 5-inch bolt circle diameter, installation aligns with factory specifications. The rotor’s nominal thickness is 0.98 inches, with a discard thickness of 0.91 inches, indicating when replacement is necessary to maintain safe braking performance.

Compatible Vehicles and Applications

• Designed specifically for Toyota 4Runner models
• Compatible with Toyota T100 trucks
• Ideal for replacing worn or damaged front or rear disc brake rotors
• Addresses issues such as brake noise, vibration, and reduced stopping power
• Suitable for vehicles experiencing rotor warping or uneven wear

Installation Notes and Tips

When installing the DuraGo BR31055 rotor, ensure the vehicle is securely lifted and the wheel assembly is removed. Clean the hub surface to remove rust or debris before mounting the rotor. Since this rotor does not include an ABS tone ring, verify compatibility with your vehicle’s ABS system. Use proper torque specifications for the six mounting bolts to avoid rotor distortion. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
