They lock into that blue arm with the two holes in it. The erm is plastic and has the spring loaded latches that hold the brushes in. If the latches have failed the brushes won;t stay in. The other option is the latch pins on the brushes have brocken or worn out. Turn the machine over and try to make the brushes latch, also push the brush release buttons several time to make sure they are working. Good-luck.
