Product Details and Specifications

The DuraGo BR900556-01 rotor features a full cast iron construction that balances durability and heat management, essential for consistent braking performance. Its vented design allows air to flow between the rotor surfaces, helping to dissipate heat more effectively during braking. The rotor measures 12.8 inches (325 mm) in outside diameter and has an overall height of 2.44 inches (62.1 mm). The nominal thickness is 0.98 inches (25 mm), with a discard thickness of 0.92 inches (23.4 mm), ensuring you can monitor wear and replace the rotor before performance is compromised.

This rotor includes five mounting bolt holes with a bolt circle diameter of 4.72 inches (120 mm) and a center hole diameter of 2.95 inches (75 mm). It is designed as a conventional, non-directional rotor without cross-drilling or slotting, suitable for standard braking systems on the BMW X3.

Compatible Applications and Common Issues Addressed

• Replacement for worn or warped rotors on BMW X3 models
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps restore proper braking performance and pedal feel
• Prevents rust-related rotor degradation with protective coating
• Suitable for vehicles experiencing brake fade due to overheating

Installation Notes and Tips

Ensure the rotor is installed on a clean, debris-free hub surface to maintain proper fitment. Verify the rotor thickness before installation to confirm it meets minimum specifications. Use appropriate torque settings for the mounting bolts to avoid rotor warping. This rotor is non-directional, allowing installation on either side of the vehicle without concern for rotation direction.
