There is a bug in the filter module. Unless you use Full HTML content type then it trims <!--break-->. The other work around is to add <!--break--> to the allowed tags of the content type you are using. For example the article content type edit page to configure the tags to use is admin/structure/types/manage/article/fields/field_tags be sure to add all the tags allowed, including the current ones; the field for input isn't prepopulated with the default for some reason.
