Detailed Product Description

The DuraGo BR31165-01 disc brake rotor is constructed from full cast iron, providing a durable and heat-resistant braking surface. Its vented design allows air to flow between the rotor surfaces, enhancing heat dissipation during braking and helping to maintain consistent stopping power. The rotor features a rust resistant coating that helps extend its service life by minimizing corrosion, especially in harsh weather conditions.

With a nominal thickness of 0.87 inches (22 mm) and a discard thickness of 0.79 inches (20 mm), this rotor meets the necessary specifications for safe and effective brake performance. The overall height of 2.78 inches (70.5 mm) and outside diameter of 11.67 inches (296.5 mm) ensure proper fitment on compatible Toyota 4Runner and Tacoma models. The six mounting bolt holes with a 5.5-inch (139.7 mm) bolt circle diameter provide secure attachment to the wheel hub.

Compatible Vehicles and Applications

• Toyota 4Runner
• Toyota Tacoma

This rotor is designed for use in standard braking systems without ABS tone rings and is suitable for vehicles requiring conventional, non-directional rotors.

Common Issues Addressed by This Rotor

• Brake rotor warping or uneven wear causing vibration
• Reduced braking efficiency due to worn or thin rotors
• Corrosion and rust buildup affecting rotor surface
• Overheating and brake fade during heavy braking
• Noise or pulsation from damaged or out-of-spec rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.79 inches (20 mm) before installation. Clean the rotor surface and hub mounting area to remove any rust or debris for proper fitment. Use a torque wrench to tighten mounting bolts to manufacturer specifications. This rotor is non-directional, so it can be installed on either side of the vehicle without concern for rotation direction.
