spartan Posted March 2, 2009 Report Share Posted March 2, 2009 you when you turn the lever upsidedown, or sideways or anything other then perfectly flat then the lever will pull all the way to the bar without anything happening, does it with brand new brakes too.I have had nothing but horrible experiences with avid, mine is on the front of my brothers mod bike with every single bolt stripped out and notches cut in them, and when u up the brake there is this horrible squeak as the brake does nothing.A rebleed might help but seriously a new brake should be top priority.Ian Quote Link to comment Share on other sites More sharing options...

I have worked on hundreds of sets of Juicy disc brakes, and for all the problems I have had to deal with I have never encountered any stripped threads. The noise could be anything really, if you don't have the knowledge to diagnose/fix the problem it might be better to take it to a shop for them to look at? Disc brakes require a lot of experience and skill to get them set-up perfect, its something worth paying for I think especially after seeing the state of most peoples disc brakes.

Lol.Really that should only happen if there is air in the system, you usually get air trapped or collected in the lever which you never even notice until the brake is upside down. I've seen this on quite a few sets of new brakes from the factory. It can be a real pain to get rid of every last air bubble when bleeding juicys.To the original poster...I suggest you give the brake a thorough clean and dry all over, check the pistons are moving freely and equally and then give it rebleed. Refit the brake and check it for signs of leeking fluid around the hose connections, pistons, and reservoir. If its not leaking anywhere, is bled perfectly and is still pulling to the bar it could be a worn seal in the master piston. I've had that happen quite a few times, the brake will lose power completely but without losing any fluid. You can buy seal kits if there are any damaged seals.
