Detailed Product Description

The DuraGo BR901536 disc brake rotor is manufactured from full cast iron, a material known for its excellent thermal conductivity and wear resistance. This rotor features a vented design, which allows air to flow between the rotor surfaces, helping to reduce heat buildup during braking. The drum-in-hat construction integrates a parking brake drum within the rotor, making it compatible with vehicles that use this combined braking system. With a non-directional brake surface, the rotor can be installed on either side of the vehicle without concern for rotation direction.

Measuring 300 mm in outside diameter and 20 mm in nominal thickness, the BR901536 meets the specifications required for various BMW models such as the 320i xDrive, 328i xDrive, 330i GT xDrive, and 428i Gran Coupe. The rotor includes five mounting bolt holes arranged on a 120 mm bolt circle diameter, ensuring proper fitment and secure installation. Note that this rotor does not include an ABS tone ring and does not have rust-resistant coating, so regular inspection and maintenance are recommended.
