I have a set of Hayes Stroker Trails on my bike, which I like well enough, but I've run into a bit of an issue. Over the spring I needed to bleed them, since it was obvious a bit of air had made it into them. I also shortened the cables while I was at it. The process was smooth enough and the pistons adjusted themselves fine. The issue I'm having now is that the rear brake will be perfect as I start my ride, but once I use the brakes for a few downhills, the system seems to lose pressure, or something. After a bit, the lever more or less sinks to the handlebars before the pads contact the rotor. If I stop and tilt the bike back I can pump them up again, but after a bit the problem re-occurs. I've checked for a leak and don't see anything.
Obviously I'd rather not bleed again. Does anyone have experience with something like this or have a suggestion of something I screwed up?
