So I just bought a new bike and decided to take a risk in buying a bike with Shimano Deore LX hydraulic disc brakes (BR-M585). I've only repaired and tuned simple wire-brakes in the past (cantilever, v-brakes etc.), but never disc brakes and certainly not hydraulic. Can anyone give me any pointers or references so I could manage to maintain the brakes in top condition for as long as possible.
The salesman at the bikeshop said that they are virtually care-free, but that sounds too good to be true, and I think he was referring to something like "come back when there's a problem and we'll fix it... for the right price".
Anyway the basic structure seems simple. There's a pin in the brakes that locks the brake-pads in place. I assume that by removing that pin I can just grab the pads and replace them? Should I pay attention to anything special? The guy at the store said that if I have to change the tire or something I should be careful not to pull the brake-lever, but didn't really explain why. The bike came with two weird plastic parts that are intended for placing between the brake-pads when the wheel (and therefore the brake-disc) is not in place. At least that's what I think they're for, haven't figured out how they would go into the brake-unit.
