Re: (ET) Motor brushes

The grinding noise I'd think is bearings.  Badly worn brushes if they are let go that long, will start to arc excessively, and cause power loss, and commutator damage. If the bearings and brushes are around the same age & hours, they all likely need replacement.

Thanks for any help,
