Every time when I open new .ai file I remove all default brushes cuz they no need me. How to make that each time when I open Illustrator I'll have my own set of brushes?
Load in your brushes how you'd like them and then save your Illustrator doc as a template file (.ait) and then copy it into the folder where your new doc profiles are stored;
%APPDATA%\Adobe\Adobe Illustrator {version} Settings\en_US\x64\New Document Profiles
Now, restart Illustrator, when opening a new doc, just choose that template under Profile.
