Unit was removed from my vehicle 2002 4 runner because of dampness and what was a small leak. I didn't bother to spend the time trying to find seals and replacing. Needed the vehicle running so just ordered a new one. Not Cheap! This unit worked perfectly with no brake system lights. Never really had to fill the reservoir but there was evidence of fluid around the area pictured on the last two photos. Small leak over time on the garage floor. Unit should be resealed or used for parts.
