Just an idea. Go to a dollar store and buy a bottle of clear finger nail polish, you don't want the polish just the brush
clean the brush good with polish remover. Your are going to use the brush to apply a light coat of Loctite universal glue
60 sec. kind. behind the rubber pad the hold or wedge in place for a little bit. Don't use super glue, a shock will loosen super glue
some people don't know that.
You can also get black weather stripping adhesive for that. Takes time for that to cure so be prepared to use something to hold it in place over night.
I think that is the way I'd go. That is the way it is held on anyway
