I had trouble in the MTB thread, they seem to say all the other threads can help but they have not. For those commuters who use hybrid bikes with disc breaks. How long do the pads last for and how often do they need to be adjusted? how often do you replace the hydrolic fluid also? Any other maintanence things I need to know about? I live in washington and it rains 24/7 and my breaks just can't aren't as good as I need in the rain.
