Maybe it’s just not working right. There are a few things you can do to try and fix the problem, but in the end, it may be necessary to reset your Illustrator brush. Here’s how to do it:

  1. Open up Illustrator and select the tool palette (Window > Tool Palette).
  2. Click on the Brush icon and select the Brush Options button (it looks like a small square with a plus sign inside of it).
  3. In the Brush Options dialog box, click on the Reset button (it looks like a small white arrow pointing down).
  4. When the Reset Brush dialog box appears, make sure that all of the checkboxes are checked and click OK. now your brush should work properly! ..
