• Vented rotor design to improve cooling and reduce brake fade
• Rust-resistant coating to extend rotor life and maintain appearance
• Nominal thickness of 0.79 inches (20 mm) with discard thickness at 0.72 inches (18.4 mm)
• Overall diameter of 11.81 inches (300 mm) with 5 mounting bolt holes
• Non-directional brake surface suitable for standard brake setups
• Compatible with BMW X3 and X4 models requiring a 5-bolt vented rotor

Product Details and Specifications

The DuraGo BR901052-02 rotor features a vented design that enhances heat dissipation during braking, helping to maintain consistent performance and reduce the risk of brake fade. Its full cast iron construction provides the necessary strength and thermal capacity for demanding driving conditions. The rotor measures 11.81 inches (300 mm) in outside diameter and has an overall height of 2.8 inches (71 mm). It includes five mounting bolt holes with a bolt circle diameter of 4.72 inches (120 mm) and a center hole diameter of 2.95 inches (75 mm). The nominal thickness is 0.79 inches (20 mm), with a discard thickness of 0.72 inches (18.4 mm), indicating when the rotor should be replaced to maintain safe braking performance. The rotor surface is non-directional and conventional, designed for standard brake systems without cross-drilling or slotting.

Compatible Applications and Common Issues Addressed

• Replacement rotor for BMW X3 and X4 models requiring a 300 mm vented disc brake rotor
• Addresses rotor wear and thickness below manufacturer specifications
• Helps resolve brake noise caused by uneven rotor surfaces or rust buildup
• Improves braking consistency by replacing warped or damaged rotors
• Prevents brake fade through enhanced heat dissipation with vented design

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 0.79 inches (20 mm). Clean the hub surface and mounting bolts to prevent uneven rotor seating. Since this rotor does not include an ABS tone ring, verify compatibility with your vehicle’s ABS system. Use proper torque specifications for the 5 mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
