Product Features and Specifications

The BR34319G rotor from MPA Electrical’s Black Series Coated Rotor line is engineered with a vented design to enhance cooling during braking, reducing the risk of brake fade. Both the disc and hat surfaces are coated to resist rust and corrosion, which is critical for maintaining rotor integrity and appearance over time. The rotor has a nominal thickness of 30.0 mm and a discard thickness of 28.0 mm, ensuring it meets standard replacement criteria. It features a smooth surface finish to provide consistent contact with brake pads and minimize noise. The rotor includes five lug holes with a mounting bolt circle diameter of 112 mm and a center hole diameter of 68 mm, matching factory specifications for the compatible Audi models.

About the Black Series Coated Rotor Line

The Black Series Coated Rotor line by MPA Electrical focuses on providing rotors with enhanced corrosion resistance through specialized coatings on both the disc and hat areas. This coating helps protect the rotor from rust, which can degrade braking performance and rotor lifespan. The line is intended for standard replacement applications, offering a balance of durability and performance for everyday driving conditions on vehicles such as the Audi A4 and S4.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Audi A4, A4 Quattro, A6 Quattro, Allroad Quattro, and S4
• Addresses rotor corrosion issues caused by exposure to moisture and road salt
• Helps reduce brake noise and vibration from uneven rotor surfaces
• Improves heat dissipation to prevent brake fade during extended use
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it is above the discard thickness of 28.0 mm. Clean the hub surface thoroughly to prevent uneven rotor mounting. Use proper torque specifications for the five mounting lug bolts on the 112 mm bolt circle. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s existing components. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.

Quality Assurance and Warranty

The MPA Electrical Black Series Coated Rotor BR34319G is a new, standard replacement part manufactured to meet OEM specifications for fit and function. The rust-resistant coating enhances durability, helping maintain rotor condition over time. Warranty details should be confirmed with the distributor or manufacturer, as they may vary by region or seller.
