Before I did my changeover, I also played with mixing DOT4 and DOT5 brake fluid, and they are definately like oil and water - they seperate and do not mix. When I shook the test tube containing the two of them, I managed to get lots of small bubbles, but the next day they were layered again.
I think that the idea of first flushing the system with clean DOT4 fluid would be a good idea if the system was not all apart before the conversion. I was told that one should have the system apart, and since we were replacing the master cylinder, combination valve, and wheel cylinders, it seemed like a good time to do the rest of the changeover. So far, the brake pedal and stopping has been good (but us flatlanders don't have to put quite the strain on the brakes as you mountain people!).
