James and Ryner Blakeborough, from Blackley, Manchester, were given anti-social behaviour orders.
They were banned from covering their faces with balaclavas and carrying screwdrivers and other weapons.
They were also banned from being racist, using fireworks and vandalising stuff. If they don't behave, they could be locked up for five years.
The court heard that the boys abused a teacher at a local primary school.
Unpleasant
It was claimed that James even asked a workman to lend him a spade so he could "batter" the teacher with it.
The judge told the brothers: "You have behaved in a way that has made life very unpleasant for residents."
