Added 11oz from a fresh can of Castrol DOT 4 brake fluid. $10.89 on Amazon. Wow! This same can was half that previously...
It really only needed about 8oz but I added a bit more since I just toss the rest of the can. There may be a slight crack in the plastic reservoir. I have tried tightening various bits around the fluid tank, but the leak remains. I'm ok just letting it be for now.
