Elixir brake doesn't release

Postby pharus » May 31st, 2013, 9:00 am

I put some Elixir 1 brakes on my bike over the winter, purchased at the mmba expo swap meet. There were take-offs from a new bike. I did have to shorten the tubes to fit my 26" bike, and I have bled the brakes repeatedly. The brakes work well, and the brake lever movement is tight and good. But occasionally, the front brake doesn't release the rotor completely after braking. So I will be riding along, and hearing some brake rub. I can flick the lever, or try a quick brake pull, but it won't go away right away. Some time later, a few minutes or so, it seems to go away on its own. Is there anything I can do about this?

sounds like the caliper is sticking for whatever reason. I have a juicy 5 where the piston seized in the caliper.

Rebuild kits are cheap (like $9 at pricepoint.com for the juicy 5 caliper kit), just order one up before the caliper and piston completely seize together like mine did. If it does completely seize, don't go all Big F Hammer on it like I did and ruin the caliper. Use some air fittings and put a little air into it and blow the piston out so you can rebuild the caliper.

my elixir 9's do the same thing. Just did a brake bleed and it seemed to of solved problem for now. I will routinely clean around piston with some rubbing alcohol, but from what I have heard this is a common problem.

mine were getting stuck at the lever. I found that the little rod that depresses the master cylinder had a bunch of crud in it. cleaned up everything and its been good.

Did that involve taking apart the whole lever mechanism? I don't think that's my issue, because the lever does pop back, but I might take a look anyway.

Thanks for the other suggestions too!

Do a search on sticky Elixir caliper here and you'll find some info on what I did to free up a piston that was hanging up.

just the lever blade and reach adjust. no need to let out any fluid or bleed

contact Avid, you probably need a new lever. I had the same problem on the rear brake lever and they replaced the lever for free. you may have to have lbs contact them and will of course need a new bleed when replaced.

Ok now i'm screwed. I was cleaning around the piston, per previous posts, squeezing the lever, the piston pushing out. Then plunk, the piston falls completely out, followed by a torrent of DOT fluid, all over my wife's mom's hand knitted afghan, which i understand now had no business being anywhere near there in the first place.

So do i lube the piston and put it back in? No lube? Wouldnt that attract more grit? Do the face grooves need an orientation? What holds the fluid in anyway? How is it ever going to hold hydraulic pressure? How do i stop the death glares from my wife?

the piston should be lubed with DOT fluid. did you also remove the snapring when cleaning the lever?

Check the SRAM/AVID website for the service manual for those brakes. It'll show how to disassemble and reassemble the pistons.

Also, there's a helluva lot of info on MTBR about this too.

Thank you everyone for the suggestions. The service manual was a great help. I'm happy to report that the brake seems to be back to normal now, after re-assembly and bleed. A trail ride will tell for sure, but seems good in my driveway.
