nope, last time I bled the brakes was about 4 months ago, with about 8 auto-x events done before the sebring event and had no problems there.

I actually brought this topic up on the Cadillac forums and I've had about 8 people reply that the same thing happens to them. Last night I even checked one of the bleeders to see if there was air in the system, and not a single little bubble came out, it was pure fluid, so air isnt getting into the system.

One thing I was reading is that with the calipers on these cars getting so hot due to the tremendous weight that they are having to stop, there could be a very very slight expansion in the metal, allowing a tiny bit of fluid to pass through the threads. that is why I am not seeing this leak anywhere else; daily driving or at auto-x events. Which makes since because I havent had one small drop of fluid drip down since I bled the brakes several months ago. I did turn my calipers a light gold-ish color from the heat too.
