Product Details and Specifications

The DuraGo BR901050-01 rotor features a full cast iron construction that balances durability and thermal management. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reduce the risk of brake fade. The rotor measures 328 mm in outside diameter and has a nominal thickness of 28 mm, with a discard thickness of 26.4 mm, ensuring it meets OEM specifications for safe operation. The rust-resistant coating helps protect the rotor surface from corrosion, which is especially beneficial in wet or humid environments. This rotor includes five mounting bolt holes arranged on a 120 mm bolt circle diameter, with a center hole diameter of 75 mm, designed for direct compatibility with BMW X3 and X4 vehicles. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Applications and Common Issues Addressed

• Replacement for worn or warped rotors on BMW X3 and X4 models
• Improves braking performance by restoring proper rotor thickness and surface condition
• Addresses brake noise and vibration caused by uneven rotor wear
• Helps prevent brake fade during extended or heavy braking
• Resolves corrosion-related rotor surface degradation

Installation Notes and Tips

Ensure the rotor is installed on compatible BMW X3 or X4 models matching the specified bolt pattern and dimensions. Verify that the rotor thickness is within the nominal range before installation and replace if below discard thickness. Clean the hub surface and mounting bolts to ensure proper rotor seating. Since this rotor is non-directional, it can be installed on either side without concern for rotation direction. It is recommended to inspect brake pads and hardware during rotor replacement to maintain optimal braking system performance.
