Detailed Description

DuraGo BR54143 is engineered as a conventional front brake rotor for vehicles that use a vented, full cast disc design. It measures 12.01 inches in outside diameter, 1.18 inches nominal thickness, and 2.13 inches overall height, with a 5-lug mounting pattern and 114.3 mm bolt circle. The rotor surface is non-directional, which supports uniform pad contact during brake service. This part cross-references Raybestos Brakes 680416 for the same application.

DuraGo has a long history in aftermarket brake manufacturing, and its rotor program is built around catalog coverage, fitment accuracy, and ISO-certified production standards. For Ford Explorer, Ford Explorer Sport Trac, and Mercury Mountaineer front brake service, BR54143 provides a direct replacement format that matches the listed dimensions and application requirements.

Common Brake Issues This Rotor Can Address

• Front brake pulsation caused by rotor wear or thickness variation
• Brake noise related to uneven rotor surface condition
• Reduced braking consistency from a worn or heat-affected rotor
• Service replacement for rotors that have reached discard thickness
• Front brake maintenance on Ford Explorer, Explorer Sport Trac, and Mercury Mountaineer models

Installation Notes and Tips

Verify rotor dimensions, hub fit, and bolt pattern before installation. Clean the hub mounting surface thoroughly to help prevent runout concerns, and inspect pads, calipers, and hardware condition during brake service. Because this rotor is non-directional and not cross-drilled or slotted, it installs as a conventional replacement rotor for the listed front applications.

Quality Assurance

DuraGo manufactures brake rotors through ISO-certified factories and builds its brake drum and rotor program around fit, form, and function requirements. The BR54143 is backed by that manufacturing approach for service on the listed Ford and Mercury front brake applications.
