• Non-directional brake surface for versatile installation
• Compatible with BMW 228i, 228i xDrive, 230i, 230i xDrive, 320i, 328d, 328i, 428i, and 428i xDrive models

Detailed Product Description

The DuraGo BR901400 disc brake rotor is constructed from full cast iron, providing a balance of durability and effective heat management. Its vented design allows air to circulate between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade under demanding conditions. The rotor features a drum-in-hat design, integrating a parking brake drum within the rotor hat, which is common in many BMW models for efficient braking and parking brake functionality.

With a nominal thickness of 0.79 inches (20 mm) and a discard thickness of 0.72 inches (18.4 mm), this rotor meets OEM specifications for thickness tolerances, ensuring safe and consistent braking performance. The 5 mounting bolt holes and a mounting bolt hole circle diameter of 4.72 inches (120 mm) align precisely with the hub assembly of compatible BMW vehicles. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• BMW 228i and 228i xDrive
• BMW 230i and 230i xDrive
• BMW 320i
• BMW 328d and 328i
• BMW 428i and 428i xDrive

This rotor is designed specifically for these BMW models, ensuring proper fitment and optimal braking performance.

Common Issues Addressed by DuraGo BR901400

• Brake rotor warping causing vibration during braking
• Excessive brake fade from overheating on vented rotors
• Worn rotor surfaces leading to reduced braking efficiency
• Corrosion and rust buildup on rotor surfaces (note: this rotor does not have rust-resistant coating)
• Incompatibility with parking brake systems requiring drum-in-hat rotors

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.72 inches) before installation
• Clean mounting surfaces to prevent uneven rotor seating
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with ABS sensors as this rotor does not include an ABS tone ring
• Inspect brake pads and replace if worn to maintain optimal braking performance

Quality Assurance and Warranty

DuraGo manufactures the BR901400 rotor to meet or exceed OEM standards for fit, form, and function. The full cast iron construction and vented design contribute to consistent braking performance under normal operating conditions. While this rotor does not feature a rust-resistant coating, proper maintenance can help extend its service life. Warranty details should be confirmed with the distributor or retailer at the time of purchase.
