The main thing of course is to keep oil/grease from getting on to expensive brake linings. Once you see the leak it is usually to late. 
I had thought of using an epoxy resin such as "emerkit" ( really good) under a speedy seleve but wasn't game enough.  Just had to say "ouch" when I got the quote for rebuilding.
