My hardtail is currently running V's. Tektro V's with bent levers that could use new cables, and you have to squeeze the crap out of them for them to do much. However, fork, frame, wheels...it's all disc ready. Anyway, my new bike has Juicy 5's, and it took me all of one ride to get spoiled rotten. So I saw some Soles on Craigslist for $40...front and rear, all parts included. My initial response was "Holy crap, hydraulic Hayes for $40!" Emailed the guy and said that if they were still in decent condition and didn't need everything replaced, I might be interested. Supposedly the brakes have about 1500 miles on them but work fine and the pads are still good. Then I checked out mtbr, and noticed they got terrible reviews. I hesitate to put too much stock in sites with reviews like that, since people who post usually are either A) really, really happy with the product, B) really, really unhappy with the product, or C) just bought the product and are trying to justify their purchase. The reviews were still bad enough to give me pause though. I'm not in a huge, huge hurry to fix up this bike, and am mainly watching for parts on Craigslist. However, I hate to pass up $40 hydraulics if they're not bad, and I do want to get the bike back in fighting condition. Thanks guys!
EDIT: It would also probably cost $15 or so in gas to get there. So it's not really a $40 brake when all is said and done...call it around $55.
