The penalty for failure to file a return is 5% a month of the tax owed max of 50%. There is also a late payment penalty of 5% a month max of 50%. Of course, there is interest (3% a year currently) on any unpaid taxes. Possibly your brother can get with the IRS to eliminate the penalties, if he voluntarily files the returns and requests a waiver. Interest is never waived. Unless you're an attorney, CPA or enrolled agent, you can't represent your brother with the IRS. Of course, you can help him file the returns.
