DuraGo BR900462 Disc Brake Rotor - Front

Reliable Disc Brake Rotor for Mazda RX-8

The DuraGo BR900462 disc brake rotor is engineered to provide consistent braking performance for your Mazda RX-8. Crafted from durable cast iron, this vented rotor is designed to maintain optimal heat dissipation and structural integrity under demanding driving conditions.

• Material: Cast iron for durability and heat resistance
• Vented rotor design for improved cooling
• Nominal thickness: 0.94 inches (24 mm)
• Discard thickness: 0.87 inches (22 mm)
• Outside diameter: 12.71 inches (322.8 mm)
• Mounting bolt hole quantity: 5 with 4.5 inch (114.3 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional full cast construction

Durable Construction and Precise Fitment

The DuraGo BR900462 rotor features a full cast iron construction that balances strength and heat dissipation, essential for maintaining braking efficiency and rotor longevity. Its vented design allows air to flow between the rotor surfaces, reducing the risk of brake fade during extended use. With a 12.71-inch outside diameter and a 5-bolt mounting pattern, this rotor is specifically designed for the Mazda RX-8, ensuring a precise fit and reliable performance. The non-directional brake surface simplifies installation, allowing the rotor to be mounted in either orientation without affecting braking function.

Compatible Applications and Performance Benefits

This disc brake rotor is compatible with Mazda RX-8 models requiring a 12.71-inch vented rotor with a 5-bolt pattern. It addresses common braking issues such as:

• Uneven rotor wear causing vibration or noise
• Reduced braking efficiency due to rotor warping
• Overheating and brake fade during aggressive driving
• Corrosion-related rotor surface degradation (note: this rotor does not include rust-resistant coating)

Installation Notes and Tips

When installing the DuraGo BR900462 rotor, ensure the mounting surface is clean and free of debris to prevent uneven rotor seating. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for directional rotation. Verify that the rotor thickness is within the nominal range (0.94 inches) and replace if below the discard thickness (0.87 inches) to maintain safe braking performance. Proper torque specifications for the 5 mounting bolts should be followed according to Mazda RX-8 service guidelines.

Quality Assurance and Warranty

DuraGo manufactures the BR900462 rotor to meet or exceed OEM specifications for fit, form, and function. While this rotor does not feature a rust-resistant coating, its full cast iron construction provides reliable durability. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation to ensure protection against defects.
