How to Install a Photoshop Brush
Photoshop brushes are located in the Preset Manager and come as .abr files. You can download and install a brush in less than a minute. (Seriously!) Here’s how to install a Photoshop brush:

Select the file to install and unzip the file.
Put the file in a location with other brushes. By default, these files are located in the Photoshop folder, then Presets, then Brushes. You know you are in the proper location when files end in .abr.
Open Adobe Photoshop and add brushes using the Edit menu, then click on Presets and Preset Manager.
Click “Load” and navigate to the new brushes and open.
You can also use the import presets function to install an entire folder of presets at one time. Once you’ve done that, you’re ready to use the new Photoshop brush.
