Detailed Description

DuraGo BR54017 is engineered as a rear brake rotor for Ford Mustang models from 1994 through 2004. The rotor uses full cast construction and a solid design, which suits rear brake systems that call for a conventional rotor profile rather than a vented or drum-in-hat style. With a 267 mm outside diameter, 70.8 mm center hole, and 5 mounting bolt holes on a 114.3 mm circle, it matches the listed Mustang rear fitment requirements. This part number, BR54017, also cross-references Continental 66448 for the same application.

Common Repair Uses

• Rear brake pulsation caused by rotor wear or thickness variation
• Brake noise related to uneven rotor surfaces
• Reduced braking consistency from worn rear rotors
• Service replacement for a rusted or heat-cycled rear rotor
• Restoring proper rear brake contact on a Ford Mustang

Installation Notes and Tips

Confirm rear fitment by matching the vehicle year, bolt pattern, center bore, and rotor dimensions before installation. Inspect pads, caliper hardware, and hub condition during service so the new rotor seats evenly. Clean the braking surfaces before use and verify rotor thickness against service limits after installation. Fits 1994-2004 Ford Mustang, rear.
