You got it a bit backwards.
Yuusha is literally "brave man" and thus translated as "Brave" sometimes. "Rokka no Yuusha", the light novel/anime, is translated as Braves of the Six Flowers.
Eiyuu is "Hero" as that's for example the translation of "eiyuuteki" is "heroic". Or "Legend of Heroes" video games series (Trails in the Sky etc) is in original version called "Eiyuu Densetsu".
While they are usually translated interchangeably, mostly because "Brave" sounds less impressive or epic than "Hero", their meanings are slightly different. Not every hero is a brave, and not every brave is a hero.
...Which is kinda fitting in context of Rokka no Yuusha, for example.
