• Vented rotor design to improve cooling
• Drum-in-hat type rotor with 6 mounting bolt holes
• Outside diameter of 12.28 inches (312 mm)
• Nominal thickness of 0.71 inches (18 mm) with discard thickness at 0.63 inches (16 mm)
• Overall height of 2.68 inches (68 mm)
• Center hole diameter of 4.25 inches (108 mm)
• Non-directional brake surface for versatile installation
• No ABS tone ring included

Technical Details and Construction

The DuraGo BR900912 rotor is constructed from cast iron, a material known for its durability and ability to withstand high temperatures generated during braking. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup and helping to maintain braking efficiency under demanding conditions. The rotor features a drum-in-hat design, integrating the drum brake surface within the rotor hat, which is compatible with specific Lexus and Toyota brake systems.

With six mounting bolt holes arranged on a 5.5-inch (139.7 mm) bolt circle diameter, this rotor fits securely on compatible hubs. The non-directional brake surface simplifies installation, allowing the rotor to be mounted in either orientation without affecting performance. Note that this rotor does not include an ABS tone ring, so it is intended for vehicles where the ABS sensor is mounted separately.

Compatible Vehicles and Applications

• Lexus GX460
• Toyota 4Runner
• Toyota FJ Cruiser

This rotor is designed specifically for these models, ensuring proper fitment and brake system compatibility. It addresses common braking issues such as rotor warping, uneven wear, and reduced stopping power due to worn or damaged rotors.

• Eliminates brake pulsation caused by warped rotors
• Restores smooth and consistent braking performance
• Reduces brake noise associated with uneven rotor surfaces
• Prevents premature brake pad wear due to rotor damage

Installation Notes and Tips

When installing the DuraGo BR900912 rotor, ensure the hub surface is clean and free of rust or debris to promote proper rotor seating. Use a torque wrench to tighten mounting bolts to manufacturer specifications to avoid rotor distortion. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for orientation. Verify compatibility with your vehicle’s brake system, especially regarding ABS sensor placement, as this rotor does not include an ABS tone ring.

Quality Assurance and Warranty

DuraGo rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The BR900912 rotor undergoes rigorous quality control to ensure consistent thickness and balance, contributing to reliable braking performance. While specific warranty details may vary, DuraGo typically offers coverage against defects in materials and workmanship. Consult product documentation or the manufacturer for exact warranty terms.
