Detailed Product Description

The DuraGo BR54007 is a conventional, vented disc brake rotor constructed from full cast iron, providing a balance of durability and thermal management. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent stopping power. The rotor’s nominal thickness of 0.71 inches ensures a solid braking surface, while the discard thickness of 0.66 inches indicates when replacement is necessary to maintain safety and performance. With an outside diameter of 10.17 inches and an overall height of 1.8 inches, this rotor fits specific Ford, Lincoln, and Mercury models, including the Ford Thunderbird, Lincoln Mark VIII, and Mercury Cougar. The five mounting bolt holes with a 4.25 inch bolt circle diameter provide secure attachment, and the non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Ford Thunderbird
• Lincoln Mark VIII
• Mercury Cougar

This rotor is designed to replace worn or damaged rotors on these vehicles, restoring braking efficiency and safety.

Common Issues Addressed by DuraGo BR54007

• Brake pulsation caused by warped rotors
• Reduced braking performance due to rotor wear
• Excessive brake noise from uneven rotor surfaces
• Overheating and brake fade during extended use
• Corrosion-related rotor degradation (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

When installing the DuraGo BR54007 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 without concern for rotation direction. Verify the rotor thickness before installation to confirm it meets the minimum discard thickness of 0.66 inches. Proper torque specifications should be followed for the five mounting bolts to ensure secure fitment. This rotor does not include an ABS tone ring, so it is compatible with vehicles that do not require this feature.

Quality Assurance and Warranty

DuraGo manufactures the BR54007 rotor to meet or exceed OEM specifications for fit, form, and function. While this product does not include a rust-resistant coating, its full cast iron construction provides reliable durability under normal operating conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
