I replaced a front brake line on my '08 Wee with ABS. Now I need to fill and bleed it. Someone posted a diagram that showed how ABS works (alas, I don't have it at my fingertips, so I can't give credit :-( ), and it showed that under normal circumstances, a bunch of the tubing is closed off from the "normal" lines; the valve positions are changed only when the ABS detects skidding. My take on this is is that there is no reasonable way to drain and refill that fluid. Is this really true? And what happens if you get some air in there?
There was another posting of a technical genius who created an electronic device that would fool the ABS mechanism into thinking the bike was skidding, and actuate it at will. I think it involved an Arduino. My hat's off to that guy. I have a degree from Famous Technology University, and I couldn't come close to creating what he did. He mentioned the possibility of making them for sale, or publicizing plans or something, but as best I can tell that never happened. Oh well.
So do I just pretend the ABS isn't there and bleed the brakes as if they were normal, and carry on? Should I be doing something like bleeding it, going out and doing a lot of stops on loose gravel, and bleeding it again, or what?
Thanks!
Edit: Oh. I don't know why I didn't find this posting before, but it would seem that there's nothing special for me to do. This doesn't quite fit with my memory of the ABS diagram I saw (which, of course, was somebody's hand-drawn effort; maybe correct, maybe not). If anyone who really knows this stuff can confirm or deny, I'd be grateful.
