A used OEM Audi Power Brake Booster, part number 4M0612103AB, also replaces 4M0612107E, 4M0612107A, and 4M0612107G. This vacuum-assisted unit multiplies pedal force to reduce stopping effort across Q7, Q8, SQ7, and SQ8 models. When the booster fails, you may notice a hard brake pedal or longer stopping distances, as the internal diaphragm loses its seal.
