Product Line: Black Series Coated Rotor

The Black Series Coated Rotor line by MPA Electrical focuses on providing rotors with protective coatings on both the disc and hat surfaces. This coating helps resist rust and corrosion, extending the rotor's service life while maintaining smooth braking performance. The BR76644G is part of this line, offering a vented rotor design that supports effective heat management during braking.

Detailed Product Description

This disc brake rotor features a vented design that promotes airflow to reduce heat buildup, which is critical for maintaining braking efficiency and preventing warping. The rotor has a nominal thickness of 30.0 mm and a discard thickness of 27.4 mm, ensuring it meets the required specifications for safe replacement. Both the disc and hat surfaces are coated to provide rust resistance, which is especially beneficial in environments prone to moisture and road salt exposure. The smooth surface finish supports consistent pad contact and braking response. With a center hole diameter of 67.1 mm and a 5-lug mounting pattern, this rotor is engineered for precise fitment on Infiniti QX30 and Mercedes-Benz B250, CLA250, and GLA250 models.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading rusted or corroded rotors to restore braking reliability
• Addressing brake noise due to uneven rotor surfaces
• Improving heat dissipation to reduce brake fade during extended use
• Ensuring proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is within the nominal range and above the discard thickness limit. Use proper torque specifications for the 5 mounting bolts to avoid rotor distortion. This rotor does not include an ABS tone ring or bearings, so confirm compatibility with your vehicle’s braking system. It is recommended to replace brake pads simultaneously for optimal braking performance.

Quality Assurance and Warranty

The MPA Electrical Black Series Coated Rotor BR76644G is a new, standard replacement part manufactured to meet OEM specifications. The coated finish provides added protection against rust and corrosion, contributing to the rotor’s durability.
