Detailed Product Description

The DuraGo BR901442 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. With a nominal thickness of 1.18 inches and a discard thickness of 1.12 inches, this rotor maintains structural integrity throughout its service life. The 13.7-inch outside diameter and five-bolt mounting pattern with a 120 mm bolt circle diameter ensure compatibility with various BMW models, including the 535d, 535i, 640i, and ActiveHybrid 5 variants. The rotor features a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Reduced braking efficiency due to worn or thin rotors
• Overheating and brake fade under heavy use
• Uneven brake pad wear linked to rotor surface irregularities
• Noise and pulsation from damaged or compromised rotors

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Clean mounting surface to prevent rotor runout and vibration
• Torque mounting bolts to manufacturer specifications for secure fitment
• Check compatibility with vehicle ABS system; this rotor does not include an ABS tone ring
