Doing mostly street riding, I must use my clutch lever 50 times to 1 use of the brake lever. All that movement probably lets in more dirt and moisture than the brake line. And with the little window in the reservoir, I change it when I can actually see color.

On my Suzuki, when I changed to braided brake lines, I changed to DOT 5 silicone fluid. That was in 1982. The best thing about it is it doesn't absorb water. Regular brake fluid does absorb water. The water in brake fluid is what boils and degrades brake performance. When the fluid becomes dirty or cloudy, it's probably absorbed water and it's time to change it.
