Help DC04 motor emitting blue sparks after new brushes were fitted?

once the original brushes have worn out your better off changing the complete motor at a cost of around £30-£40 the reason for new brushes emitting sparks is that the part of the motor ware the brushes run aginst (comutator) has burnt .

The motor comutator may be burnt from the old carbon brushes you could try cleaning it with some fine grade emery paper, if this does't work then you need a new motor.
