I missread.......I thought the wheel had fluid all over it as well. I doubt powersteering fluid, lines are way to high in the engien bay to get fluid in the wheel well. As for brake line failure the wheel would most likely be wet or soaked if the wheel well is soaked....simple physics. I wonder if you ran through a puddle of fluid from an accident ect. Like said above, check your fluids if your not low then just write it off to something in the road.

If your pumping the brakes and nothing is leaking, your ok. It wont seal itself up, a ruptured line is a ruptured line.
