Juicy pad replacement - need bleeding?

edited August 2012 in MTB workshop & tech
After a particularly sandy and soaking wet weekend last week I've bought new pads front and back. The old ones literally had nothing left on them, it was like riding with 60grit sandpaper on the pads.
I've gone through the process of loosening off the calliper, pushing the pots back and fitting the new pads.

I got some leakage of brake fluid when I pushed the pads back, and the brakes are total sponge now, they barely bite at all. Do they just need a bleed, or are the seals gone?

    When I've pushed them back I've never noticed any leakage so it doesn't sound good. How old are they? My seals were still keeping the fluid in after 3 years (replaced due to sticky pistons).

    Does any fluid come out when you pull the lever? If there's no leak, when you bleed them you can put a bit extra fluid in if necessary. Watch you don't get any fluid on the pads!

    They're about three and half years now I think. There's so little bite at the moment I don't think there would be enough pressure on the piston to force any more fluid out.

    Seems a seal has gone then.

    Took it to the LBS today, because I can't pick up reasonably priced bleed kit in time for my next ride, and..... they refused to look at it. Told them about the loss of fluid and he said Elixir are crap brakes, and they can't guarantee any work on them. I need new brakes apparently.... Bit surprised to be honest.

    Going to ignore them and try bleeding them myself.

    If a seal has gone, bleeding will do nothing.
    Sounds like a rubbish shop by the way.

    Nope, avids are shite, shouldn't come as a surprise, they appear to be the most troublesome brakes ever. And as CD said, bleeding won't do anything if you've got a damaged seal.
    Well, not anything useful anyway.

    What I didnt mention is that the leakage was from the juicy calipers, not the avid levers. I guess the seals could have gone in the calipers but I can source those locally if I need them.

    @cooldad they're a well known shop in these parts too. Not the first time I've had that sort of helpful advice, so I'll travel a couple of miles further to the next nearest in the future. I feel like I'm going to the headmasters office every time I go in there.

    what the hell are you on about? Juicys are a kind of brake made BY Avid.

    I must be lucky, my Juicy 3SLs are coming up four years old and have been totally trouble free. Never needed a bleed or fettling.

    Lucky, yes. Because a few reliable units in a sea of failures doesn't make them worthwhile brakes.
    Besides, I refuse to take anyone's word when they say "my brakes work fine", because I've ridden so many bikes with allegedly well set up brakes, only to find that my definition of "good" and their definition of "good" differ substantially.

    Calm down? Who's that meant to be aimed at? Nobody here seems anything other than calm.
  • I've had a few different models of avids and had problems with them all at some point or another, I've been with hopes now for a long time and had no problems what so ever,

    Well that was worth the effort. A good bleed both ends and they're all good again. New pads in and they're as good as new.

    Great universal kit from epic bleed solutions worked a treat...
