Have you tried the local hardware stores? Several chains carry them in those flip down drawers where they have oddball hardware, toggle switches, springs and such. That size sounds like an old sewing machine motor. That would be another place to check, if you have an old fashioned repair shop in your area that repairs, rather than replaces the motors.

Ace True Value hardware stores in this area stock loads of brushes - a bit pricey ($4 each!) but beats hunting and shipping handling costs.

If they don't have the exact one - they are easy to file to size and shape.

You can always sandpaper down a brush that is too large, just be sure to get all the powder and sand off the brush before placing it in the motor. I have done this many times for old shavers and other various small motors that use brushes. The new material may be a little softer or harder than the original material the brushes were made of, but that is not a big issue compared to getting the motor running again.

Have you tried your local auto electrician?

These guys were pretty cheap.

There are others.

When I needed one for a fan motor in my car, the only source I could find was at a vacuum cleaner repair shop.

A long long time ago I had to do the same on a small motor. I took apart a D-size carbon zinc battery and the center core was a carbon rod that I file down to match the size of the carbon brush. It worked fine.

Try your local hardware store. I know the ACE Hardware near where I live has an assortment.

That's a clever idea in a pinch, I hadn't thought of it. In most cases it'd be easier to buy the right or similar brush though rather than file one from scratch.
