Overview of DuraGo BR901378 Disc Brake Rotor

The DuraGo BR901378 is a cast iron vented disc brake rotor designed specifically for Ford Mustang models. Engineered for reliable braking performance, this rotor offers consistent thickness and durability to maintain safe stopping power under various driving conditions.

  • Material: Full cast iron construction for strength and heat dissipation
  • Vented rotor design to improve cooling and reduce brake fade
  • Nominal thickness: 1.18 inches (30 mm) with discard thickness at 1.12 inches (28.5 mm)
  • Outside diameter: 12.6 inches (320 mm) for precise fitment
  • Mounting bolt pattern: 5 holes with 114.3 mm bolt circle diameter
  • Non-directional brake surface for versatile installation
  • Conventional rotor type compatible with standard brake systems

Detailed Product Description

The DuraGo BR901378 disc brake rotor is constructed from full cast iron, providing a balance of durability and thermal conductivity essential for effective braking. Its vented design allows air to circulate between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade. With a nominal thickness of 1.18 inches and a discard thickness of 1.12 inches, this rotor maintains structural integrity throughout its service life. The 12.6-inch outside diameter and 5-bolt mounting pattern with a 114.3 mm bolt circle diameter ensure compatibility with Ford Mustang brake assemblies. The rotor features a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

  • Compatible with Ford Mustang models requiring a 12.6-inch vented disc brake rotor
  • Suitable for conventional brake systems without ABS tone ring requirements
  • Designed for use in standard front or rear disc brake setups

Common Issues Addressed by This Rotor

  • Brake rotor warping or uneven wear causing vibration during braking
  • Reduced braking efficiency due to overheating or brake fade
  • Excessive rotor thickness loss affecting stopping power
  • Noise or pulsation from worn or damaged rotors
  • Compatibility issues with mounting bolt patterns and rotor dimensions

Installation Notes and Tips

  • Ensure rotor thickness is above discard thickness (1.12 inches) before installation
  • Clean mounting surfaces to prevent rotor misalignment
  • Torque mounting bolts to manufacturer specifications for secure fitment
  • Check brake pads for wear and replace if necessary during rotor installation
  • Verify rotor is non-directional to allow flexible installation orientation
