Scaling Brushes
 
       
  [Multiple selected brushes with single bounding box]Brushes can be re-sized after they have been created, either singly or in a group. First select the brush or brushes you wish to scale. If multiple brushes are selected, note that a single bounding box now encompasses all of the brushes and has a single set of handles.

Drag any handle to move that plane and resize the brush(es). It is usually easier to scale brushes in an orthogonal
view pane. It can be done in a Perspective View pane but you may have trouble locating the handle you need and judging the potential effect of moving it.
