About the Black Series Coated Rotor Line

The Black Series Coated Rotor line by MPA Electrical focuses on providing rotors with a protective coating that helps resist rust and corrosion. This coating extends the rotor's service life and maintains braking efficiency, especially in environments prone to moisture and road salt. The BR73045G is part of this line, combining vented rotor technology with a coated finish to support consistent braking performance on compatible BMW vehicles.

Product Details and Specifications

The BR73045G disc brake rotor features a vented design that promotes better heat dissipation during braking, reducing the risk of brake fade. Both the disc and hat surfaces are coated, providing a rust-resistant barrier that helps maintain rotor integrity over time. With a nominal thickness of 20.0 mm and a discard thickness of 18.4 mm, this rotor meets standard replacement criteria. The smooth surface finish ensures even pad wear and reliable stopping power. Note that this rotor does not include an ABS tone ring or bearings.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on compatible BMW models
• Addresses brake noise caused by uneven rotor surfaces
• Helps reduce rust buildup that can impair braking efficiency
• Improves heat management to prevent brake fade during extended use
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify rotor thickness with a micrometer to confirm it meets minimum specifications. Use proper torque settings on wheel lug nuts to avoid rotor warping. This rotor is designed for direct replacement on specified BMW 228i, 230i, 320i, 328i, and 428i models, including xDrive variants. No ABS tone ring or bearings are included, so retain existing components if applicable.
