Avid Elixir R bleed problem
Hi, I have a problem with Avid Elixir R front brake. They lose power rapidly when hot so I bled them once and then a second time and the stopping power has not improved. What I've noticed during the bleeding procedure is a strange air noise coming out under the lever while I decompress/compress the suringe. I suppose the brake should be a closed system and not let air out or in under the lever ( I guess that is where the piston is ). Anyway, after I bled the brake the lever felt just like the lever of the rear brake. It had a nice crispy feel and I could feel the exact moment when the pads hit the rotor. But after pressing the lever 20 or so times that feeling went away and now it feels a lot different. Lever resistance is progressively increasing as I pull it and I can't tell the moment when the pads hit the rotor. Could it be that the system is letting air in under the lever so that the feel changes so quickly ? Oh, and both times I bled the brake there were bubbles. If it is letting the air in could I warrant it ?
Yes you have...
air getting into the system some how. Could you warrant it, possibly, depends on how long you've had the brakes. Warranty on the Elixers is for a period of 2 years from the date of purchase. But you will have to go through a dealer.
"I do whatever my Rice Cripsies tell me to!"
on elixirs, air is sucked into the lever past the piston seal when pulling up on the bleed syringe, easier than any other brake. When sucking air out of the mc, use very little force on the syringe. PITA
The air comes in and out even with a light pressure. I'm taking it to the shop tomorrow.
I'm hoping you are using the Avid bleed kit.
But there is a revised brake bleed kit for the Elixers vs. the Juicy's
Who can order parts from Innolite Design? Anybode can order (except North America, until distributors are contracted),
I guess this isn't thread necromancy, because my issue is about Elixir R and symptoms are the same. The lever audibly sucks air in when I pull on lever syringe even with smallest force. When I pull on caliper syringe (with lever pulled to the handlebar), massive amount of air is also sucked in mysteriously.
I have the official Elixir lever rebuild kit and am going to try replacing lever internals with it.
All previous Elixir (R and CR) brakes that I bled never had anything like these symptoms.
Well, replacing lever internals helped (extract old assembly, clean lever bore with isopropyl alcohol, lubricate new assembly with Hope (Hunter UK branded) silicon grease, install it), air sucking is gone. I wonder if it's because of the new diaphragm sealing the bore better, or the amount of silicon grease I used.
Quick and dirty tip for removing the plastic snap ring if your circlip pliers don't fit: thread 2 14G spokes in those holes, put them through 7 mm combination wrench and use something to wedge between spokes above the wrench (I used the handle of a 8 mm wrench, it's a nice shape for that).

JRP, thanks for the tip. I'm about to bleed my Elixir R's, a little nervous about it. +Rep!
does your lever make those air sucking noises too? If it doesn't, then you don't have to extract its internals, so there's no need to operate that snap ring.
Understood, I'm just trying to be prepared for the worst, just in case!
