• Material: Cast iron for strength and durability
• Vented rotor design to improve heat dissipation
• Nominal thickness of 0.96 inches (24.5 mm) with discard thickness at 0.88 inches (22.4 mm)
• Overall diameter of 10.12 inches (257 mm) suitable for specific vehicle fitments
• Four mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional full cast construction without rust-resistant coating

Detailed Product Description

The DuraGo BR31109 is a conventional, full cast disc brake rotor made from cast iron, providing a balance of durability and heat management. Its vented design allows air to flow between the rotor surfaces, reducing the risk of brake fade during extended use. With a nominal thickness of 0.96 inches and a discard thickness of 0.88 inches, this rotor meets the specifications required for safe and effective braking. The rotor’s 10.12-inch outside diameter and four mounting bolt holes with a 114.3 mm bolt circle diameter ensure proper fitment on compatible Hyundai and Mitsubishi models.

Compatible Vehicles and Applications

• Hyundai Tiburon
• Hyundai Expo and Expo LRV
• Mitsubishi Lancer
• Mitsubishi Galant
• Mitsubishi Sigma

This rotor is designed specifically for these models, providing a direct replacement that maintains factory braking performance.

Common Issues Addressed by DuraGo BR31109

• Brake rotor warping causing vibration during braking
• Reduced braking efficiency due to worn or thin rotors
• Overheating and brake fade from insufficient heat dissipation
• Uneven brake pad wear linked to rotor surface irregularities
• Noise and pulsation during braking caused by rotor defects

Installation Notes and Tips

When installing the DuraGo BR31109 rotor, ensure the mounting surface is clean and free of rust or debris. Verify the rotor thickness before installation to confirm it is above the discard thickness of 0.88 inches. Use proper torque specifications for the four mounting bolts to avoid rotor distortion. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.

Quality Assurance and Warranty

DuraGo manufactures the BR31109 rotor to meet industry standards for material quality and dimensional accuracy. While this rotor does not feature a rust-resistant coating, its cast iron construction provides reliable durability under normal operating conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
