Detailed Product Description

The DuraGo BR31204 is a full cast, vented disc brake rotor specifically designed for Toyota 4Runner and Tacoma vehicles. Its cast iron construction provides a balance of durability and effective heat dissipation, which is critical for maintaining braking efficiency during extended use. The vented design allows air to flow between the rotor surfaces, reducing the risk of overheating and brake fade. With a nominal thickness of 0.87 inches and a discard thickness of 0.79 inches, this rotor meets OEM specifications for safe replacement. The rotor features six mounting bolt holes with a 5.5 inch (139.7 mm) bolt circle diameter, ensuring proper fitment and secure installation. The non-directional brake surface allows for flexible rotor orientation during installation.

Compatible Vehicles and Applications

This disc brake rotor is compatible with the following Toyota models:

  • Toyota 4Runner
  • Toyota Tacoma

It is designed to replace worn or damaged rotors, restoring braking performance and safety.

Common Issues Addressed by DuraGo BR31204

  • Brake rotor warping causing vibration during braking
  • Excessive rotor wear leading to reduced braking efficiency
  • Overheating and brake fade from insufficient rotor cooling
  • Corrosion or surface damage affecting brake pad contact
  • Uneven rotor thickness causing noise or pulsation

Installation Notes and Tips

  • Ensure rotor thickness is above discard thickness before installation
  • Clean mounting surface to prevent rotor misalignment
  • Torque mounting bolts to manufacturer specifications
  • Inspect brake pads and replace if worn to ensure optimal performance
  • Check for ABS sensor clearance as this rotor does not include a tone ring
