The seal at the back of the master cylinder (near that bolt) is leaking. You will need to replace the master cylinder. Should not be too expensive, and just about any shade tree/backyard mechanic should be able to do it for cheap. If you want to try it yourself, here is a guide: https://www.2carpros.com/articles/how-to-replace-a-brake-master-cylinder
