If you are sixteen then you are old enough to make a mature decision. But I know that my best friend has an abusive father and calling Child Services is too hard for to do because she loves her parents too much. You should consider talking to your parents, even if it seems hopeless so that you will be able to look back and say that you took all the precautions necessary before doing something drastic. Whatever you do, do not leave your brothers to this abusiveness because it might have severe aftereffects (drug addicts, alcoholics, etc). If talking doesn't work, then talk to a close relative who will tell them to stop or go live with an aunt or uncle which will probably be the result of calling child services. But you have to remember that once you call them, life will get a little more complicated and your brothers will need a father figure present to show them right from wrong. However, if all of that fails and your parents do not allow you to leave their presence and their abuse, use Child Services as a warning and if that doesn't work, then you should actually call. Depending on where you live, you can get a local number. Just google it: "Child Service Contact Us - (city)" and you'll get a number. Hope this helps!
