Well this is about my brother violating his probation he has been out for two months and every pee test was good except for fridays this past Friday so now he is jail and worried about him I just want to know how much time he will do ? Can someone please help

Well most likely he will stay in jail till the hearing and the judge will give him another chance on probation, but you never know it is all up to the judge. They can send him back to prison to do the entire time of his original sentence. If his original sentence was for drugs this is more likely.
