• Overall height of 1.91 inches (48.6 mm)
• Outside diameter of 11.77 inches (299 mm)
• Five mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Detailed Product Description

The DuraGo BR54142 disc brake rotor is constructed from full cast iron, providing a robust and heat-resistant braking surface essential for maintaining consistent stopping power. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to prevent brake fade. With a nominal thickness of 0.98 inches (25 mm) and a discard thickness of 0.91 inches (23 mm), this rotor meets the specifications required for safe and effective brake performance. The rotor’s 11.77 inch (299 mm) outside diameter and 1.91 inch (48.6 mm) overall height ensure proper fitment on compatible vehicles.

Designed as a conventional, non-directional rotor, the BR54142 can be installed on either side of the vehicle without concern for directional rotation. It features five mounting bolt holes spaced on a 4.5 inch (114.3 mm) bolt circle diameter, matching the hub specifications of the Ford Fusion, Lincoln MKZ, Mazda Milan, and Mercury Zephyr models. This rotor does not include an ABS tone ring and does not have rust-resistant coating, so proper maintenance is recommended to prevent corrosion over time.

Compatible Vehicles and Applications

• Ford Fusion (select years)
• Lincoln MKZ (select years)
• Mazda Milan (select years)
• Mercury Zephyr (select years)

This rotor is intended for use in disc brake systems on these vehicles, providing replacement or upgrade options for worn or damaged rotors.

Common Issues Addressed by DuraGo BR54142

• Brake pulsation caused by warped rotors
• Reduced braking efficiency due to worn rotor thickness
• Overheating and brake fade from insufficient heat dissipation
• Noise and vibration from uneven rotor surfaces
• Corrosion-related rotor surface degradation (requires maintenance)

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.91 inches) before installation
• Clean rotor surface and hub mounting area to prevent uneven contact
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check brake pads for wear and replace if necessary during rotor installation
• Perform a proper bed-in procedure after installation to optimize braking performance

Quality Assurance and Warranty

DuraGo manufactures the BR54142 rotor to meet industry standards for material quality and dimensional accuracy. While this rotor does not include a rust-resistant coating, its full cast iron construction ensures structural integrity under normal operating conditions. Warranty coverage details should be confirmed with the product documentation or supplier, as they may vary by region or distributor.
