as gaz hinted there are no brushes in an induction motor. whatever is wrong it is not the brushes. is there a condensor as an axciter? if so try sustituing nv equiaelant can or check for any breaks in wiring /fuse from plug to interior connections. moulded on plug? cut it off and replace with a proper one. hope this isn't too late or perhaps it may help somebody else. cherio
