Detailed Product Description

The DuraGo BR31373 disc brake rotor is constructed from full cast iron, providing a balance of durability and effective heat management. Its vented design allows air to circulate between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade under normal driving conditions. With a nominal thickness of 0.98 inches (25 mm) and a discard thickness of 0.91 inches (23 mm), this rotor maintains structural integrity throughout its service life. The rotor’s outside diameter of 10.94 inches (278 mm) and five mounting bolt holes with a 4.5-inch (114.3 mm) bolt circle diameter ensure proper fitment on compatible Mazda 3 and Mazda 3 Sport vehicles. The non-directional brake surface allows for installation on either side of the vehicle without concern for rotor orientation.

Compatible Vehicles and Applications

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

• Mazda 3
• Mazda 3 Sport

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

Common Issues Addressed by DuraGo BR31373

• Brake pulsation or vibration caused by warped rotors
• Reduced braking efficiency due to worn rotor thickness
• Overheating and brake fade from inadequate heat dissipation
• Noise or squealing resulting from uneven rotor surfaces
• Corrosion-related rotor damage (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surfaces to prevent uneven rotor seating
• Torque mounting bolts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Check for ABS sensor compatibility as this rotor does not include an ABS tone ring
