Product Details

DuraGo has over 45 years of aftermarket manufacturing experience, and the BR5404 reflects that focus on fit, form, and function. It is manufactured by ISO-certified factories and built for front brake service on classic Ford Mustang, Mercury Cougar, and Mercury Montego models listed in the fitment data. This part cross-references MOOG Chassis Products 5404 for the same application.

Common Brake Issues This Part Can Address

• Rotor wear that has reached discard thickness
• Brake pulsation caused by an out-of-spec rotor surface
• Hub-related service needs during front brake repair
• Noise or uneven pad contact from worn braking surfaces
• Front-end brake service on vehicles with the listed 5-lug pattern

Installation Notes and Tips

Verify rotor diameter, bolt circle, stud thread size, and bearing cup requirements before installation. Clean the hub mounting surface thoroughly and inspect pads, bearings, and caliper hardware for wear before reassembly. Because this is a front rotor and hub assembly, confirm left/right orientation is not required for your application and follow the vehicle service manual for torque and bedding procedures.

Quality Assurance

DuraGo manufactures this rotor assembly in ISO-certified factories and builds its brake program around catalog accuracy and OE-style fitment requirements. The BR5404 is engineered to meet the expected requirements for fit, form, and function on the listed Ford and Mercury front brake applications.
