If you like to move/customize the brush sets, I normally make a copy of them and then I moved the "copy" to the new brush palette. If you have made a mistake and moved some of the brushes from their default locations, you can download the entire set of brushes for SketchBook from this post.

NOTE: It only works with SketchBook 8.x or higher.
