macでbrew-cask本体のアンインストール方法

初めての質問で至らない点があると思いますがご容赦ください...

"Brew Cask" のアンイントール方法がわからないです

macのパッケージ管理ツールHomeBrewの拡張brew caskをインストールしたのですが
オリジナルのApplicationが、/Applicationにないというのが合わなくて....
brwe cask自体を削除しようと思ったんですが、homebrewのように公式にUninstallコマンドがなくて...
Uninstallの方法を知っている方がいれば教えて下さい。

インストールした時はbrew tap caskroom/caskでインストールしました

試したこと

誰か記事にしている人はいないかと調べたのですが
brew cask でインストールしたappのアンインストール方法の情報しか見つけれませんでした...

補足情報e

一応 本当に一応ですがbrew doctorの情報を載せときます
brew doctorのほうはyour system is ready to brew.なので問題なさそうです。
