This Audi brake booster (OEM 4E1612105E) is a used genuine part removed from a donor vehicle. Also known simply as the brake booster, it replaces numbers 4E1612107A, 4E1612107, and 4E1612107B. The booster amplifies pedal force to make braking easier and more responsive; a failing unit often causes a hard pedal or reduced stopping power. Fits Audi A8 Quattro and S8 models equipped with 4.2L V8, 5.2L V10, or 6.0L W12 engines.
