Technical Details and Construction

The BR31294-01 rotor features a full cast iron construction, providing a balance of durability and thermal management essential for braking systems. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat and reduce brake fade during extended use. The rotor’s drum-in-hat configuration integrates a parking brake drum, compatible with the brake systems on Lexus 4Runner, GX470, and Toyota FJ Cruiser and Sequoia models. The rust-resistant coating extends the rotor’s service life by protecting against corrosion, especially in humid or wet environments.

• Lexus 4Runner
• Lexus GX470
• Toyota FJ Cruiser
• Toyota Sequoia

It is designed to replace original equipment rotors with matching specifications, ensuring proper fit and function for these models.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear reducing braking efficiency
• Corrosion and rust buildup on rotor surfaces
• Overheating and brake fade during heavy use
• Noise and uneven brake pad contact due to rotor surface damage

Installation Notes and Tips

When installing the DuraGo BR31294-01 rotor, ensure the mounting surface is clean and free of debris to maintain proper rotor alignment. Verify the rotor thickness is within nominal specifications before installation. Since this rotor is non-directional, it can be installed on either side without concern for rotation direction. Use the correct torque specifications for the 6 mounting bolts to avoid distortion. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle’s ABS system.
