Interesting discussion and a good read.
Unfortunately, I would get kicked out of your car club for admitting this, but I have never replaced brake fluid in any vehicle I have ever owned.
I keep my cars a long time, as I've mentioned before, and I have never had brake issues with any vehicle I've owned, beyond normal maintenance (pads, shoes, drums, rotors, whatever).
I'm still using my 2002 Pathfinder as a daily driver, with just over 313,000 Kms on it, and not only have I never flushed the brake fluid, but I am still on the original rear brake shoes and drums.
They've never been replaced in 16 years. I check them annually, and there is still about 30-40% left on the shoes. I use my hand/emergency brake every day as well, and that still works perfectly too.
I guess with my new Mazda 6, I'll have to rethink the brake fluid strategy, but I sure as heck won't be changing it out at 24K miles (about 40K Kms.).
Oh well, happy motoring everyone.
