Black Series Coated Rotor Product Line Details

The Black Series Coated Rotor line by MPA Electrical focuses on providing rotors with protective coatings that resist rust and corrosion. This coating helps maintain rotor integrity and appearance over time, especially in environments prone to moisture and road salt exposure. The BR78005G rotor benefits from this coating on both the disc and hat surfaces, contributing to longer service life and reduced maintenance.

Technical Specifications and Features

This disc brake rotor is vented, allowing for better heat dissipation during braking, which helps prevent brake fade. The nominal thickness of 29.9 mm ensures durability, while the discard thickness of 28.0 mm indicates when the rotor should be replaced to maintain safe braking performance. The smooth surface finish promotes even pad wear and consistent braking feel. The rotor includes five mounting lug holes with a bolt circle diameter of 112.0 mm and a mounting bolt hole diameter of 15.3 mm, designed to fit securely on compatible Audi A6 and A6 Quattro models.

Applications and Problem Solving

• Replacement for worn or warped rotors on Audi A6 and A6 Quattro
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust-related rotor degradation in humid or salty environments
• Improves braking consistency by maintaining proper rotor thickness
• Supports heat management to reduce brake fade during extended use

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the nominal thickness specifications. Clean the mounting surface and verify the bolt pattern matches the vehicle’s hub assembly. Since this rotor does not include bearings or an ABS tone ring, reuse existing components if applicable. Proper torque specifications should be followed when securing the rotor to avoid warping.

Quality Assurance and Warranty

The MPA Electrical Black Series Coated Rotor BR78005G is a new, standard replacement grade rotor designed to meet OEM specifications for Audi A6 and A6 Quattro vehicles. The rust-resistant coating enhances durability, and the product condition ensures reliable performance. Warranty details should be confirmed with the distributor or manufacturer.
