Technical Details and Construction

The DuraGo BR900728-01 rotor features a full cast iron construction, providing a solid and durable braking surface. Its vented design allows air to flow between the rotor faces, helping to dissipate heat more effectively during braking. This reduces the risk of brake fade and maintains consistent performance under demanding conditions. The rotor’s rust-resistant coating extends its service life by protecting against corrosion, which is especially beneficial in wet or humid environments.

With a nominal thickness of 1.18 inches (30 mm) and a discard thickness of 1.12 inches (28.4 mm), this rotor meets OEM specifications for thickness tolerances. The overall height of 2.87 inches (73 mm) and outside diameter of 13.7 inches (348 mm) ensure proper fitment and compatibility with the specified BMW models. The rotor includes five mounting bolt holes with a 4.72 inch (120 mm) bolt circle diameter and 0.58 inch (14.7 mm) bolt hole diameter, matching factory mounting requirements.

Compatible BMW Models and Applications

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

• BMW 335d
• BMW 335i
• BMW 335is
• BMW 335i xDrive
• BMW 335xi
• BMW X1

It is designed for use as a direct replacement rotor to restore braking performance and maintain safety standards on these models.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear leading to reduced braking efficiency
• Corrosion and rust buildup affecting rotor surface integrity
• Overheating and brake fade during extended or heavy braking
• Uneven brake pad wear due to rotor surface irregularities

Installation Notes and Tips

Ensure the rotor surface and hub mounting area are clean and free of debris before installation. Verify rotor thickness to confirm it meets minimum specifications. Use proper torque settings on mounting bolts to avoid rotor distortion. Since this rotor does not include an ABS tone ring, confirm compatibility with your vehicle’s ABS system. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.
