Detailed Product Description

The DuraGo BR900728 is a conventional, full cast disc brake rotor made from cast iron, providing a balance of durability and heat resistance. Its vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent stopping power. The rotor measures 13.7 inches (348 mm) in outside diameter and features a nominal thickness of 1.18 inches (30 mm), with a discard thickness of 1.12 inches (28.4 mm), indicating when replacement is necessary to maintain safe braking performance.

With five mounting bolt holes spaced on a 4.72 inch (120 mm) bolt circle diameter and a center hole diameter of 3.11 inches (79 mm), this rotor is engineered to fit specific BMW models including the 335d, 335i, 335is, 335i xDrive, 335xi, and X1. The non-directional brake surface allows for flexible installation without concern for rotor orientation. This rotor does not include an ABS tone ring and does not feature cross-drilled or slotted surfaces.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Restores braking performance on BMW 335i and X1 models
• Addresses rotor thickness below manufacturer specifications
• Improves heat dissipation to reduce brake fade during extended use
• Suitable for vehicles experiencing uneven rotor wear or noise

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surfaces to prevent rotor runout
• Torque mounting bolts to manufacturer specifications
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Check for ABS sensor compatibility as this rotor does not include a tone ring
