Buggered avid juicy 5 bleed...

Hi guys,

Just bled my front juicy 5, all looking good so suitably chuffed with lack of calamity. Until I went to remove the wedge from between the pistons, as it was stuck in there. One of the pistons is detracted fine, but on the other side the round bit with the piston in is sticking out. Doesn't seem to want to move and not sure whet I need to do. :?

Will try to get a pic now

Any advice would be gratefully received!

    too much fluid in the system remove bleed screw on the lever and push the piston in.

    Cheers nicklouse

    Trying that but just can't get it to shift. Can I use the syringe to draw some fluid from the calliper or will make things worse?

    hi,

    sounds like you have a seized piston because when you undo the bleed screw any overspill flows out and you should be able to prize the piston back, so maybe some corrosion on the piston?

    also if you used the avid bleed kit and have bled this correctly there should be the right amount in there.

    Good luck and keep us up to date on how you get on.

    bigger pic?

    or a pic in focus :wink:http://www.pinkbike.com/photo/4880924

    it is quite a way out... it could be a case of it being pushed back off center and jamming.

    hold the other one back and gently pull the lever to get the other one moving and then carefully push back in. if the sides of the piston need a clean do so.

    give the whole thing a good wash out with some brake cleaner, just to remove anything that might be causing it to seize. Then ease the piston back in.. it might also be worth removing the lever bleed screw and accepting that you will need to re-bleed after.

    Sorry! Took loads of pics trying to get one in focus on my phone - and evidently used the wrong one (I blame it on the stress!)

    Try as I might, I couldn't get the piston back in, so opened both the bleed port on the lever and the calliper and when enough fluid had dripped out, the piston popped straight back in. A quick rebleed, using a sturdier wedge in the piston and 5 minutes later - jobs a good'un.

    Carlos- I used a red dog racing bleed kit which I got 2nd hand for £15. Not a chance in hell was I spending £30+ on the avid one! Lesson learned about being such a tightarse though...
