My answer had nothing to do with racing, it had to do with all the research I did on brake fluids over the past two months when I started rebuilding my brakes. I talked to all my friends who track their cars, I read the archives, I googled, I asked around at other forums.
I don't see any contradiction in my statements above: "a long time" is compared to generic DOT 3. Certainly your car won't lose all braking after a year, but changing it once a year provides very crisp braking all the time. It's a conservative default that I like to recommend.
And as for my comment about Rara and Demon's advice: I happened to be on at the same time as he asked the question, so I said what I had been thinking about it, since I had also noticed the disagreement. I was just voicing my opion, since as you noticed, I have one about everything. I'm obcessed with vehicle dynamics and mechanics, and the reasons that you could get two very different opinions of the same fluid were of interest to me.
On the other hand, your only contributions to this thread have been to criticize my posts. What gives?
