Part number BR78004G
Rear disc brake rotor application
Coated finish for added rust resistance
OE-style vane design for efficient cooling
New, regular-grade rotor
Built for quiet, smooth braking with reduced vibration and fade

Detailed Description

This MPA Electrical brake rotor is made for rear axle service on Audi A4, Audi A4 Quattro, Audi A5 Sportback, Audi A5 Quattro, Audi A6, Audi A6 Quattro, Audi A7 Quattro, Audi Q5, and Audi allroad applications. It is a direct-fit rear brake rotor choice for drivers searching for a coated rear rotor for 2008-2025 Audi models, including the BR78004G part number for replacement matching.

The coated surface helps protect the rotor from rust, while the vane layout supports heat dissipation during repeated stops. That makes it a practical option for daily driving, stop-and-go traffic, and vehicles exposed to wet or salted road conditions.

What It Helps Address

Rear brake pulsation from worn or uneven rotors
Rust buildup on exposed rotor surfaces
Brake noise caused by rotor wear or surface irregularity
Reduced stopping consistency during repeated braking
Heat-related fade from poor rotor cooling

Installation Notes

Verify rotor diameter, rear position, and brake configuration before installation. Fitment includes 300mm diameter and solid rotor notes on select Audi A4, A4 Quattro, A6, A6 Quattro, A7 Quattro, and Q5 applications, so match the vehicle’s original brake setup to the listing details. For best results, inspect pads, caliper condition, and hub surfaces during rotor replacement.
