• Non-directional brake surface for flexible installation
• Center hole diameter of 2.28 inches (58 mm) for proper hub alignment

Product Details and Specifications

The DuraGo BR900870 rotor is designed specifically for Subaru Impreza vehicles requiring a drum-in-hat style disc brake rotor. Its full cast iron construction ensures durability and effective heat management during braking. The vented rotor design allows air to flow between the rotor surfaces, helping to dissipate heat and maintain braking efficiency. With a 5-bolt mounting pattern and a 12.44-inch outside diameter, this rotor matches factory specifications for a direct replacement. The nominal thickness of 0.79 inches and discard thickness of 0.71 inches provide clear service limits to maintain safe braking performance.

Compatible Applications and Common Issues Addressed

• Replacement for worn or warped rotors on Subaru Impreza models
• Resolves brake pulsation caused by uneven rotor surfaces
• Addresses reduced braking efficiency due to rotor thinning
• Suitable for vehicles with drum-in-hat parking brake systems
• Helps eliminate noise and vibration from damaged rotors

Installation Notes and Tips

When installing the DuraGo BR900870 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper fitment. Verify the rotor thickness before installation to confirm it meets the minimum discard thickness of 0.71 inches. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle’s ABS system. Use proper torque specifications on the mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
