Audi brake master cylinder, OEM part number 4G1611021A, also replaces 4G1611021. This used genuine component from a donor vehicle converts pedal force into hydraulic pressure for the braking system. When the master cylinder fails, you may experience a spongy pedal, fluid leaks, or a pedal that sinks to the floor, compromising stopping power. It serves the A6, A6 Quattro, A7 Quattro, RS7, S6, and S7, paired with engines including the 3.0L supercharged V6 and 4.0L turbocharged V8.
