Detailed Product Description

The DuraGo BR31300 disc brake rotor is designed specifically for Mitsubishi Lancer and Mirage vehicles, ensuring proper fit and function. Constructed from full cast iron, this rotor provides a balance of strength and heat resistance. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade under normal driving conditions. The rotor features a nominal thickness of 0.94 inches (24 mm) and a discard thickness of 0.88 inches (22.4 mm), which helps maintain braking efficiency and safety over time. With an outside diameter of 10.08 inches (256 mm) and four mounting bolt holes spaced on a 100 mm circle, the BR31300 rotor fits securely on compatible Mitsubishi models without the need for modifications.

Common Applications and Problem Solving

  • Replacement for worn or warped rotors on Mitsubishi Lancer and Mirage
  • Addresses brake pulsation caused by uneven rotor surfaces
  • Improves braking consistency by restoring proper rotor thickness
  • Helps reduce overheating and brake fade during regular driving
  • Suitable for vehicles experiencing noise or vibration from damaged rotors

Installation Notes and Tips

  • Ensure rotor thickness is above discard limit before installation
  • Clean mounting surfaces to prevent rotor misalignment
  • Torque mounting bolts to manufacturer specifications for secure fit
  • Check brake pads for wear and replace if necessary during rotor installation
  • Perform a test drive to verify braking performance after installation
