Hello all, I have a motor on a Panasonic vacuum where the one of the carbon brushes is arcing badly on one side but the other side is perfectly fine and does not arc. Would I have to replace the brush, or use a sanding stone. This is for work and I do not want to mess this up.

Replace both brushes then commuter stone blow off residue after vacuum is turned off.

Before replacing brushes, see if you can measure current draw with a 'kill a watt' device or ammeter. If much above rated current draw then motor is failing with shorting windings.
