no haters please. just like to fix this ideally : )
just fitted new internals to an elixir 5 lever and ither is still an air leak from around the lever end of the cylinder when i go to bleed it.
does this suggest damaged inside of cylinder/lever housing?
did have a good clean in there. couldn't see any damage. possibly 1 or 2 MINISCULE bits of guff i couldn't get shifted. i spose they could be the prob. not quite sure where the seal is made which air is passing, but i can hear it and lots of endless bubbles into the syringe.
anyone with similar experience?
don't mind just getting shot of em and getting set of SLX, which i'm sure some will suggest, but quite like the elixirs otherwise, and alsways better to fix stuff.
This probably isn't going to help much, but are you 100% sure the air leak isn't somewhere in the bleed kit? Could be a bad seal between the plastic tube and the metal screw-in attachment.
I only suggest this because I had the same issue myself 😳
Also sweepstake entry in early: I think 7 people will tell you to get Shimanos.
thanks jimoiseau. hadn't thought of that.
but yes i am sure, i can hear it squeaking by in the push-rod area.
having said that, i've put it together and it seems fine so far.
i'd love to get some shimanos, and won't need much encouragement.
i reckon 7's about right aye!
It's probably the bleed kit... but if you want an excuse to buy Shimano's I'll take the Elixir's off your hands if they are going cheap...
I've heard that leak on two or three sets of elixir 5s. I replaced the internals on one lever, but the noise was still there. It still performs fine a year later.
Are you absolutely sure that you've bled correctly with the port at the top of the system? Did you cycle the lever 10 times as you held it under vacuum? are they tiny little bubbles or big (>1mm) ones?
they are big bubbles ~2mm dia. and they just keep coming. i've since been out for a ride tho, and did have some back brake, but was spongy an too far back to the bar ( with rech adjust right out, which also means bite point)
yes i cycled lever, port was at top as in lever was on bars, but in normal position. the noise cleary goes with the bubbles. same frequency. may try again to rule out bleed kit altogether.
thanks for input everyone.
aye so bled again this morning. now is worse and is clearly a leak around the piston/bladder assembly, as sram call it.
when pulling on levers syringe, air stream becomes constant, not just bubbles.
i'll have the lever apart one last time to see if i can see any damage.
can anyone confirm, that this pist/blad ass. seals just under the circlip part? or further in? i can quite work it out

How hard are you pulling on the syringes to create the vaccuum?
Are you using the plastic syringes with the red plastic attachments? If so I'm willing to bet your syringes are screwed.
You maybe lucky and only have one knackered syringe... I've successfully bled avid's with one syringe - caliper first (leave the bleed screw in the lever) prep the syringe a third full and vacuum the air out of the brake with the syringe and then do the lever in the same way.
I had this problem, I was trying to overhaul the whole system after a leak just like yours. I gave up in the end and bought some..........
[i]torsoinalake[/i] about right, hard enought o creat a vaccuum, not hard enough to overstrain other parts of the system or syringe
[i]wurzelcube[/i] so where exactly are you saying the syringes must be screwed? the seal st the brass end where it screws into the lever presumably?
just to keep an open mind and be sure of what i reckon, i'll try again in the morning with both syringes. ididn't swap them round this morning; it is possible.
i actually had oil coming out the back end of the cylinder today, where i say the leak is, during the pushing-from-the-caliper-while-releasing-lever part.
[i]jamiemcf[/i] for the record, i have already given in and bought some.....
XT : )
When I said screwed I meant knackered / broken.
Well aye. Didn,t think you meant screwed-in...
So which bit are you suggesting knackered or broken?
anyways, it's not the syringes. it's clearly the lever.
it's spares or repairs then.
