Vacuum motor brush replacement

I have replaced vacuum motor brushes before, but the last install resulted
in excess brush arcing. Is the armature at fault?

as long as the timming has not been changed...brush plate installed correctly..then YES>>>armature most likely bad.

Are you sure you have the right brushes? if they are too soft, the increased abrasion results in a shower of sparks (seen it often enough, when I put the wrong brushes into motors...)
