Detailed Product Description

The DuraGo BR901778-01 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design enhances airflow to help dissipate heat generated during braking, reducing the risk of brake fade under normal driving conditions. The rotor features a rust-resistant coating that helps protect against corrosion, which is especially beneficial in regions with wet or salty road conditions.

With a nominal thickness of 0.67 inches (17 mm) and a discard thickness of 0.59 inches (15 mm), this rotor maintains structural integrity throughout its service life. The overall height measures 1.82 inches (46.3 mm), and the outside diameter is 11.22 inches (285 mm), matching OEM specifications for a precise fit. The rotor includes five mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter and 0.51 inch (13 mm) hole diameter, ensuring compatibility with the specified Subaru models.

Compatible Vehicles and Applications

This DuraGo disc brake rotor is compatible with the following Subaru vehicles:

  • Subaru Crosstrek
  • Subaru Forester
  • Subaru Impreza

It is designed for use in conventional braking systems without ABS tone rings and features a non-directional brake surface, allowing for flexible installation on either side of the vehicle.

Common Issues Addressed by This Rotor

  • Brake rotor warping or uneven wear causing vibration
  • Corrosion and rust buildup reducing braking efficiency
  • Reduced heat dissipation leading to brake fade
  • Worn rotor thickness below manufacturer specifications
  • Compatibility issues with OEM replacement parts

Installation Notes and Tips

When installing the DuraGo BR901778-01 rotor, ensure the mounting surface is clean and free of debris to promote proper seating. Verify rotor thickness before installation to confirm it meets minimum discard thickness specifications. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s braking system. Use proper torque specifications on mounting bolts to avoid rotor distortion.
