Detailed Product Description

The DuraGo BR54111 disc brake rotor is constructed from full cast iron, providing the necessary strength and thermal capacity to withstand the demands of daily driving and towing. Its vented design allows air to flow between the rotor surfaces, helping to reduce heat buildup and maintain consistent braking performance. The drum-in-hat construction integrates a drum brake surface within the rotor hat, making it suitable for rear brake applications on compatible Ford F-150 and Lincoln Mark LT trucks. This rotor features six mounting bolt holes with a 5.31-inch bolt circle diameter, ensuring a secure fit. The non-directional braking surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Ford F-150 (rear disc brake applications)
• Lincoln Mark LT (rear disc brake applications)

This rotor is designed to replace worn or damaged rear disc brake rotors on these specific models, restoring proper braking function and safety.

Common Issues Addressed by DuraGo BR54111

• Brake pulsation or vibration due to warped rotors
• Reduced braking efficiency from worn rotor thickness
• Excessive brake noise caused by uneven rotor surfaces
• Overheating and brake fade during heavy use
• Corrosion-related rotor damage (note: no rust resistant coating included)

Installation Notes and Tips

When installing the DuraGo BR54111 rotor, ensure the mounting surface is clean and free of debris to promote proper rotor seating. Verify that the rotor thickness meets or exceeds the nominal thickness of 0.79 inches (20 mm) and replace if below the discard thickness of 0.73 inches (18.5 mm). Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. Use proper torque specifications for the six mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.

Quality Assurance and Warranty

DuraGo manufactures the BR54111 rotor to meet or exceed OEM specifications for fit, form, and function. The cast iron construction and vented design contribute to consistent braking performance and durability. While this product does not include a rust resistant coating, proper maintenance can help extend rotor life. Warranty coverage details should be confirmed with the product documentation or supplier.
