Product Overview

DuraGo manufactures aftermarket brake components with a focus on catalog coverage, fit, form, and function. The BR901374 rear rotor follows that approach with ISO-certified manufacturing and application-specific dimensions for Mustang rear brake replacement. If you are replacing a worn or heat-affected rear rotor on a Ford Mustang, BR901374 provides the correct vented, conventional rotor format for the listed applications. This part cross-references Ford OE numbers such as FR3Z2C026A and GR3Z2C026C for the same application.

Common Reasons for Replacement

• Brake pulsation from rotor thickness variation
• Scoring, grooves, or uneven pad contact on the rear rotor surface
• Excessive wear approaching discard thickness
• Noise or vibration during rear braking
• Corrosion-related rotor deterioration on serviceable brake systems

Installation Notes

Verify rear axle fitment, bolt pattern, center bore, and rotor dimensions before installation. Clean the hub mounting surface thoroughly to reduce runout concerns, and inspect pads, calipers, and hardware condition during rotor replacement. Follow the vehicle service procedure for torque specifications and brake bedding after installation.

Quality Assurance
