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.\u003c\/p\u003e\u003cp\u003eDesigned 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.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFord Fusion (select years)\u003c\/li\u003e\n\u003cli\u003eLincoln MKZ (select years)\u003c\/li\u003e\n\u003cli\u003eMazda Milan (select years)\u003c\/li\u003e\n\u003cli\u003eMercury Zephyr (select years)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis rotor is intended for use in disc brake systems on these vehicles, providing replacement or upgrade options for worn or damaged rotors.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed by DuraGo BR54142\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake pulsation caused by warped rotors\u003c\/li\u003e\n\u003cli\u003eReduced braking efficiency due to worn rotor thickness\u003c\/li\u003e\n\u003cli\u003eOverheating and brake fade from insufficient heat dissipation\u003c\/li\u003e\n\u003cli\u003eNoise and vibration from uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eCorrosion-related rotor surface degradation (requires maintenance)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (0.91 inches) before installation\u003c\/li\u003e\n\u003cli\u003eClean rotor surface and hub mounting area to prevent uneven contact\u003c\/li\u003e\n\u003cli\u003eTorque mounting bolts to manufacturer specifications for secure fitment\u003c\/li\u003e\n\u003cli\u003eCheck brake pads for wear and replace if necessary during rotor installation\u003c\/li\u003e\n\u003cli\u003ePerform a proper bed-in procedure after installation to optimize braking performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDuraGo manufactures the BR54142 rotor to meet industry standards for material quality and dimensional accuracy.
