    Do I need a new bladder for my Hayes Hydros?

    I've never taken apart any hydros b/4 but I'm ready to concur them. I think it's the only part I haven't taken apart or rebuilt yet on the bike.

    Anyway, the bike took a nasty fall today on a slippery bridge. Luckily it was at the very end of the ride. Here's the problem. The lever is still attached to the pin that goes into the bladder, but it appears the pin was pulled out of the bladder. Or whatever holds it in there. The rubber bladder part is still connected. It looks like the pin just 'popped' out of sockt per say. If I take it apart, will I discover it just 'popped' out or is the bladder hosed? I'm guessing the latter but since I've never worked on them b/4, I can't way for sure.

    I forgot to mention that these are the older style brakes. They're about 4 years old. So they aren't the HFX ones.

    Thanks to all the experts who reply!
    Why would I need more than one gear?

    Should be easy to fix.Look on Hayes website for master cylinder replacement instructions, you will need small snap ring pliers to get to the washer that the ball end of the "pin" pulled thru. If you can re-flatten the washer and reasemble, possibly rebleed you will be good. hardest part might be getting the small snap washer off, but with patience its easy. Don't let it fly away or you'll lose it . The bladder is the rubber that surrounds the master cylinder

    Thanks skywaybuzz! That was exactly the problem. And hydros aren't that hard to work on.
