You know that the carbon dust from the brushes acts as a lube for the brushes.I was working in a electric shop rebuilding electric motors and we didn't clean or turn the comutator unless there was visible damage. The carbon is only bad when it builds up and cause heat issues. But is actualy a lube between the com. and the brush.
Well that settles it. I will leave them dry and dirty; goes against everything I like to do; but it makes sense. Thanks for the info ! !
Jeff,
Yea, You know Me too well; how I jump to conclusions; I was going to hold off commenting on all the upgrades I've just done; but Someone asked, and I couldn't help myself.
So far, I really like them. I'll keep You posted.
