Yes, I am being accurate. They do not increase cooling. They do not affect brake performance at all. Their purpose is to do what you stated last - "prevent unwanted heat from transferring to the brake hoses and other heat sensitive parts of the car" (such as rubber suspension bushings). Nothing to do with brake performance.
