You can be charged with anything the police have probable cause to believe that you did. Whether they have probable cause often depends on whose side of the story they believe. The way you explain it, it sounds like you used a reasonable amount of force in self-defense, but that doesn't mean you can't be charged if they don't believe you. If there is any possibility that your brother contacted to police first, I would strongly suggest you contact an attorney.
I am not your lawyer... yet. If you would like me to be, give me a call at 512-535-1081, or send me an email to firstname.lastname@example.org.
You can be charged. It just depends who the police believe. It's often a race to call the cops. I would report the offense if you haven't already.

Charged, yes. Convicted, maybe.
There is no confidentiality online. Volunteering to answer this question does not create an attorney-client relationship. The accused is presumed innocent until proven guilty beyond a reasonable doubt. The likelihood of a positive outcome- exoneration or a mitigated sentence- is increased with the help of an experienced criminal litigator. Seek out an experienced criminal litigator for a free consultation. If you cannot find one on Avvo, search at the National Association of Criminal Defense Lawyers (NACDL.org) Speak to several attorneys and hire the one that makes you feel confident and comfortable.
