The vacuum pump supplies the vacuum required for the power brake booster to work. If it fails or has a problem, the vehicle will be left without assisted braking. Without the brake booster, the brake pedal will be stiff and will require considerably more effort to stop the vehicle, as well as negatively impacting fuel economy. Vacuum also plays a roll in operating automatic door locks and climate controls found in many Mercedes models of this era.
