DuraGo BR54111 Disc Brake Rotor - Rear

DuraGo BR54111 Rear Drum-In-Hat Rotor

The DuraGo BR54111 is a rear drum-in-hat disc brake rotor built from cast iron for vehicles that use an integrated parking brake drum inside the rotor hat. It is a vented, non-directional rotor with a full cast construction and a 6-lug bolt pattern for select Ford F-150 and Lincoln Mark LT applications.

Built by DuraGo, a long-running aftermarket brake manufacturer, this rotor reflects the brand’s focus on catalog coverage, fitment accuracy, and ISO-certified production standards. The BR54111 is a direct-fit replacement for rear brake service on 2004-2011 Ford F-150 and 2006-2008 Lincoln Mark LT 6-lug models.

Detailed Description

The DuraGo BR54111 rear brake rotor is engineered for vehicles that require a drum-in-hat rotor design, where the parking brake mechanism is housed inside the rotor assembly. Its full cast, vented cast iron construction supports stable braking characteristics and service durability, while the non-directional surface simplifies installation and rotor rotation during brake work. This part cross-references Raybestos Brakes 680182 for the same application.

Compatible With 2004-2011 Ford F-150, rear 6 lug, and 2006-2008 Lincoln Mark LT, rear 6 lug. Use BR54111 when servicing rear brake systems on these trucks and when replacing a worn or out-of-spec drum-in-hat rotor. The BR54111 part number is also useful when searching for a direct replacement rotor for Ford F-150 rear brake repair.

Common Problems This Rotor Can Address

• Rear brake pulsation from rotor wear or thickness variation
• Brake noise caused by a worn or heat-affected rotor surface
• Parking brake service needs on drum-in-hat rear brake systems
• Reduced braking consistency from a rotor below discard thickness
• Fitment issues when replacing the rear rotor on 6-lug Ford F-150 or Lincoln Mark LT models

Installation Notes and Tips

Verify rear axle fitment, 6-lug bolt pattern, and drum-in-hat rotor requirements before installation. Measure the existing rotor and compare outside diameter, center hole diameter, and thickness specifications to confirm proper replacement. Inspect the parking brake shoes and hardware inside the hat area during service, and clean the hub mounting surface before installing the new rotor. The BR54111 is a rear application for 2004-2011 Ford F-150 and 2006-2008 Lincoln Mark LT models.
