Classic master cylinder problem. Re-sealing it might alone do the job, you don't know if the inside of the cyl is all rusty/nasty until you look. I have seen ones that failed after many years, that did _not_ have a bore problem. That may vary with your usage patterns, maintenance history, and maybe even local climate.
