I'm having nothing but fun times with my Avid Juicy 3's.
I have two problems and would like some help from you good people.
Unfortunately, I don't have the cash right now to buy some new brakes and would like to learn how to fix these issues myself.
Firstly, I have a stuck piston on my front caliper. Is this fixable?
Secondly, I have managed to snap the head off my torx screw driver and it's stuck in the head of the screw in my leaver. Any ideas how I can get this out?

Screw can be replaced, try [url= http://www.singletrackworld.com/forum/topic/avid-juicy-bleed-screw ] THIS [/url]thread. If you can get the old one out that is...
As to the piston, loads of guides, try [url= http://www.bikeradar.com/forum/viewtopic.php?p=14668121 ] THIS [/url]from another website, or Google is your friend.
typical PITA for Avid, but should be fixable. Good luck,

Bleed screw...poke with a dart or compass point to fettle it out.
Piston...lever other piston back in with flat screwdriver while pumping the lever gently. Stuck piston should start to move. When it does let it come out a few mm then push back & repeat. Then spray with some WD40. Keep on until both move freely. Mount the caliper upside down on one bolt to hold it steady while you work.
rustler is correct apart from do not use wd 40 as a lube. Use the correct brake fluid or red rubber grease.
WD40 will rot /swell the seals. The key thing is to get it moving, then drip some DOT fluid around the piston to help it get lubricated. Repeat until it moves in the same manner as as the other one. Can take a while...
Put your pads well away from the calipers!
Thanks for the info folks, much appreciated.
I shall post back my results.
