Your brother will not learn to "control" his anger unless he gets therapy to help him understand "what his anger is about" and there is usually something that he never got validated for and because of that he is angry at "everyone".

You need to find a way to get yourself out of his path of anger. I had to learn how to do that myself with my brother somehow. And I did see some of the reasons "why" he was angry so I WAS always very frightened.
