I've been riding my Kona Cinder Cone pretty regularly for about a year now, it's my first foray into hydraulic disk breaks (Hayes Nines), and I have no idea when to change the pads or what to look for to know if they need to be changed.
Once they stop working, or you start to notice a large difference in stopping power, get new pads. You can also take them off and look at them to see how much pad is left.
