Detailed Product Description

The DuraGo BR900938 disc brake rotor features a full cast iron construction that provides durability and effective heat dissipation during braking. Its vented design allows air to flow between the rotor surfaces, helping to reduce heat buildup and minimize brake fade during extended use. With an outside diameter of 12.59 inches (319.8 mm) and a nominal thickness of 0.79 inches (20 mm), this rotor meets the precise specifications required for BMW X5 and X6 vehicles. The drum-in-hat design integrates a parking brake drum within the rotor, offering a compact and efficient braking solution. The rotor includes five mounting bolt holes with a bolt circle diameter of 4.72 inches (120 mm), ensuring secure attachment to the vehicle hub. This rotor does not include an ABS tone ring and features a non-directional brake surface, allowing for flexible installation without concern for rotor orientation.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking performance due to rotor thickness below discard limits
• Resolving excessive brake noise or vibration linked to rotor surface issues
• Upgrading to a vented rotor for improved heat management in demanding driving conditions
• Ensuring compatibility with BMW X5 and X6 brake systems requiring drum-in-hat rotors

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below 0.72 inches (18.4 mm)
• Ensure mounting surfaces are clean and free of debris for proper rotor seating
• Torque mounting bolts to manufacturer specifications to avoid rotor warping
• Check compatibility with existing brake pads and hardware on BMW X5 or X6
• Inspect related brake components such as calipers and wheel bearings during installation
