A used OEM Audi Brake Master Cylinder, part number 4G1611021, is a genuine hydraulic component from a donor vehicle. This cylinder converts pedal force into hydraulic pressure to actuate the braking system. A common failure symptom is a soft or sinking brake pedal, indicating internal seal leakage. It serves models including the A6, S6, and RS7, and is compatible with engines ranging from the 2.0L turbocharged I4 to the 4.0L V8.
