Detailed Product Description

The DuraGo BR901660 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. With a nominal thickness of 0.79 inches and a discard thickness of 0.72 inches, this rotor maintains structural integrity throughout its service life. The rotor features a conventional, non-directional braking surface, making it compatible with a wide range of brake pads and caliper setups.

Measuring 11.81 inches in diameter and 2 inches in overall height, the BR901660 is designed to meet the exact specifications required by BMW and Mini vehicles, ensuring proper fit and function. The five mounting bolt holes with a 4.41 inch bolt circle diameter provide secure attachment to the wheel hub assembly.

Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation or noise
• Restores braking performance on BMW 228i Gran Coupe and Mini Cooper models
• Addresses rotor thickness below manufacturer discard limits
• Improves heat dissipation to reduce brake fade during extended use
• Suitable for vehicles experiencing uneven rotor wear or surface scoring

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surface and hub to prevent rotor runout
• Use proper torque specifications for mounting bolts to avoid warping
• Inspect brake pads and calipers for wear or damage during rotor replacement
• Perform a bed-in procedure after installation to optimize braking performance
