Detailed Product Description

The DuraGo BR901780 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface. Its vented design allows air to flow between the rotor faces, reducing heat buildup and helping to prevent brake fade during extended use. With a nominal thickness of 30 mm and a discard thickness of 28 mm, this rotor maintains structural integrity throughout its service life. The rotor measures 333.5 mm in outside diameter and features five mounting bolt holes arranged on a 114.3 mm bolt circle diameter, ensuring precise fitment on Subaru Ascent vehicles. The non-directional brake surface simplifies installation by allowing the rotor to be mounted in either orientation.

Compatible Vehicles and Applications

• Compatible with Subaru Ascent models requiring a 333.5 mm vented disc brake rotor
• Designed for use in conventional braking systems without ABS tone rings
• Suitable for replacement of worn or damaged front or rear rotors on Subaru Ascent
• Addresses issues such as brake noise, vibration, and reduced stopping power

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (28 mm) before installation
• Clean rotor surface to remove any protective coatings or debris prior to mounting
• Torque mounting bolts to manufacturer specifications to avoid warping
• Inspect brake pads and calipers during rotor replacement for optimal performance
