The brush sizes are 6.5mm x 7.5mm x 12.5mm....just search ebay for this size and they fit 91223 and 91222 Chicago grinders

Not knowing where you live, I have quite a large selection of brushes if you ever slide through my town....
And we can always file down a bigger one to fit...

Well according to this website where this grinder is sold, and in the manual, it states that the tool accepts 4 inch accessories with either 5/8" or 7/8" arbor hole (arbor diameter is 5/8" with a 7/8" adapter). So technically you could purchase ANY brand of accessories as long as you stick to those specs. The website does sell a few accessories, but with that information, you should be able to find much more online and in stores.

Harbor Freight(tm) usually has a manual for each tool they sell, and that manual usually has an exploded diagram of the tool, and a list of all its little parts.

Strangely this manual shows one brush, rather than the usual two.

Although just because a part is listed in a manual does not mean they actually sell all those little replacement parts separately.  I think you have to call customer support ( 800-444-3353) and ask about that part.

In the event they do not sell the brushes separately, you should try to measure the dimensions of the brushes, and then set out on a quest to replace them somewhere else. I'm not sure where you'd start looking.  I tried Google(tm), and this place came up, and they've got lots of pictures.

Also if you just want to look at pictures of brushes, there is of course Google Images:

There's no telling where your quest might take you.  I don't know if there are actual brick-and-mortar stores that have motor brushes. Or maybe it is possible to fabricate them, or grind a brush down a brush from something else into a shape that fits your motor.
