I doubt that you're doing the search wrong - there just aren't any results!
The A forum has only existed for a few years - so we certainly haven't covered every possible problem.
If you don't have an Owner's Manual - you can download one from here, too.
In regards to the Parking Brake, I vaguely recall one or two others have corrosion issues. Suggest pulling the cover and at a minimum spraying a good penetrating oil into the area.
