Brolin checked into a rehab facility recently in Northern California ... a source told Us Weekly he realized he needed help and is committed to his sobriety.
TMZ broke the stories ... Josh got into into a drunken barfight in Santa Monica earlier this month that was caught on video ... and that same weekend, he tangled with a cab driver after rear-ending the guy.
