Black Series Coated Rotor Product Line Details

The Black Series Coated Rotor line by MPA Electrical focuses on providing rotors with enhanced corrosion resistance through a specialized coating on both the disc and hat surfaces. This coating helps extend rotor life by reducing rust formation, which is particularly beneficial for vehicles exposed to moisture and road salts. The BR78019G rotor maintains standard replacement specifications while offering this added protection, making it suitable for maintaining the braking integrity of Audi models listed.

Technical Specifications and Features

This disc brake rotor features a vented design that promotes better heat dissipation during braking, reducing the risk of brake fade. The nominal thickness of 33.9 mm ensures structural integrity, while the discard thickness of 31.5 mm indicates the minimum safe thickness before replacement is necessary. Both the disc and hat are coated to resist rust, which helps maintain rotor performance and appearance over time. The smooth surface finish supports even brake pad wear and consistent braking response. The rotor includes five lug holes with a mounting bolt circle diameter of 112 mm and a center hole diameter of 68 mm, ensuring proper fitment on compatible Audi vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Audi A6 and A6 Quattro
• Addressing brake noise and vibration issues caused by uneven rotor surfaces
• Improving braking consistency on Audi A7 and A7 Quattro models
• Preventing rust-related rotor degradation on Audi A8 Quattro vehicles
• Maintaining proper rotor thickness to ensure safe braking performance

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 33.9 mm. Clean the hub surface thoroughly to prevent uneven rotor mounting. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s existing components. Proper torque specifications should be followed when tightening lug nuts to avoid rotor warping.

Quality Assurance and Warranty

The MPA Electrical Black Series Coated Rotor BR78019G is a new, standard replacement part manufactured to meet OEM specifications. The rust-resistant coating enhances durability, contributing to consistent braking performance. Warranty details should be confirmed with the distributor or manufacturer, as they may vary by region.
