Detailed Product Description

The DuraGo BR901442-01 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface that withstands the demands of daily driving and spirited performance. Its vented design enhances airflow, helping to dissipate heat more effectively and maintain consistent braking performance under load. The rotor features a rust-resistant coating that helps prevent corrosion, extending the service life and maintaining rotor integrity over time.

With a nominal thickness of 30 mm and a discard thickness of 28.4 mm, this rotor meets OEM specifications for thickness tolerances, ensuring safe and reliable braking. The 348 mm outside diameter and five mounting bolt holes with a 120 mm bolt circle diameter are engineered for direct compatibility with BMW 535d, 535i, 640i, and ActiveHybrid 5 models, including xDrive and Gran Coupe variants. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• BMW 535d and 535d xDrive
• BMW 535i and 535i xDrive
• BMW 640i and 640i Gran Coupe
• BMW 640i xDrive and 640i xDrive Gran Coupe
• BMW ActiveHybrid 5

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive brake fade from overheating
• Corrosion and rust buildup reducing rotor lifespan
• Uneven brake pad wear due to rotor surface irregularities
• Noise and reduced braking efficiency from worn rotors

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify that the rotor thickness is within the discard limits to maintain safe braking performance. Use proper torque specifications for the five mounting bolts to avoid rotor distortion. Since this rotor is non-directional, it can be installed on either side of the vehicle without concern for orientation. It is recommended to replace brake pads when installing new rotors to optimize braking efficiency.
