dripping break fluid, expansion tank

Hi guys, over the last week i noticed i was dripping break fluid, i did not have the time to check really from where until this past weekend.

i noticed it was leaking from the break expansion tank but the only problem was i could not make out if it was from the expansion tank itself or the bedding, i checked real oem for pictures and it looks like the tank is inserted into 2 plugs that go into the master cylinder.

is it a known issue that those plugs can wear out or i have some kind of a crack on my tank?

has anyone replaced the plug or the tank itself, i just added some ate blue fluid, might have to empty it i guess this weekend to replace the tank/plug.

and would it be also the cylinder itself? That would be expensive

any ideas, suggestions, thank u in advance
