Product Line Details: Black Series Coated Rotor

The Black Series Coated Rotor line by MPA Electrical focuses on providing rotors with a protective coating that resists rust and corrosion. This coating is applied to both the disc and hat surfaces, which helps maintain rotor integrity and appearance over time. The BR77112G rotor is part of this line, offering a standard replacement grade suitable for maintaining factory-level braking performance on compatible Mazda vehicles.

Technical Specifications and Features

This disc brake rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade. The nominal thickness of 28.0 mm ensures durability, while the discard thickness of 26.0 mm indicates when the rotor should be replaced to maintain safe braking. The smooth surface finish promotes even pad wear and consistent braking response. The rotor includes a rust-resistant coating on both the disc and hat, which helps prevent corrosion and extends the rotor's lifespan. It is designed with a 5-lug hole pattern, a 68.0 mm center hole diameter, and mounting bolt hole circle diameters of 114.3 mm (4.5 inches) with 0.52 inch bolt hole diameter, ensuring proper fitment on specified Mazda models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mazda 6 and CX-5
• Addresses brake noise caused by uneven rotor surfaces
• Helps reduce rust buildup that can affect braking efficiency
• Improves heat management to prevent brake fade during extended use
• Restores smooth braking performance and pedal feel

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 26.0 mm before installation. Clean the rotor surface to remove any protective oils or residues prior to mounting. Verify the 5-lug bolt pattern and center hole diameter of 68.0 mm match the vehicle specifications. Use proper torque settings on mounting bolts to avoid rotor warping. This rotor does not include ABS tone ring or bearings, so retain existing components if applicable.
