Yep, DOT5 in my car. I had done a road ralley last year and was onthe brakes pretty hard. Non-power discs. I had no issues. I had all new components. One trick someone told me about was to place the open can in a pan of boiling water. It could be a romur, but DOT5 will entrain air a little easier. So by heating it up, you are expanding the bubbles enough to rise to the surface. I did it, I figured it couldn't hurt.
