I have one of the brushes for my SS4000, and I just now looked at it to see what it does. It rides/cleans the channel that the LEFT side of the slide carrier rides in. If you look at the bottom of the slide carrier you will see the left side has a thin fin as contrasted to the wide flat surface on the right side (the side with the gear teeth).
The brush is a spiral "pipe cleaner" brush that cleans the channel the thin fin goes in. Because the brush is tubular, and its long axis is aligned with the length of the fin, I can't tell if it is cleaning the bottom, left, or right side of the channel the fin rides in. I suspect it cleans both sides, but that's just a guess. The centerline of the brush is aligned with the bottom of the fin, and the brush is about 1/8" diameter.
