Used BMW Power Brake Booster Genuine OEM part number 6799927, also supersedes 6858913. This used booster came from a donor vehicle. It is designed for both the BMW i3 and i3s, covering the 0.6L 647CC range-extender (BEV REX) engine and the pure battery-electric (BEV) variant. The power brake booster amplifies pedal force for smooth stopping; when it fails, the brake pedal becomes hard and requires much more effort to press.
