Detailed Description

DuraGo BR54078 is a conventional front brake rotor engineered for fit, form, and function on select Ford Super Duty platforms. It measures 13.03 inches in outside diameter and uses a vented, non-directional braking surface to support consistent pad contact and serviceability. This rotor fits 2000-2005 Ford Excursion, front; 2000-2004 Ford F-250 Super Duty, front; 2000-2004 Ford F-350 Super Duty, front; and 1999 Ford F-250 Super Duty, front from 3/22/99 with Mono Beam Axle, plus 1999 Ford F-350 Super Duty, front from 3/22/99. This part cross-references Four Seasons 66914 for the same application.

Common Repair Uses

• Front brake rotor replacement for worn or below-spec rotors
• Correction of brake pulsation caused by rotor wear or thickness variation
• Service replacement after scoring, heat checking, or surface damage
• Restoration of braking performance on Ford Excursion and Super Duty front axles
• Replacement for rotors that no longer meet discard thickness limits

Installation Notes

Verify rotor diameter, center hole, bolt circle, and axle configuration before installation. For 1999 Ford F-250 Super Duty and F-350 Super Duty applications, confirm the production date and, where listed, the Mono Beam Axle note. Inspect pads, calipers, and hub surfaces during brake service to help ensure proper rotor seating and braking performance. DuraGo BR54078 is a front rotor only and should be matched to the vehicle’s confirmed front brake specification.

Quality Assurance

DuraGo manufactures this rotor through ISO-certified factories and builds its brake drum and rotor program around catalog accuracy and OE-style fit, form, and function. The BR54078 reflects that manufacturing approach for Ford Excursion and Super Duty front brake service.
