Have talked to more than a few yeti owners that keep getting spongy brake handle after riding a bit. On some bikes I have worked on, and my own I would have to bleed the air out of the caliper a couple times a day. The problem is the piston o-rings have a manufacturing defect in them that won’t let them leak fluid but introduce air into the system. Reported this before just trying to help someone if needed
Is your yeti brake making air

Awesome and useful information
I have a bunch of Yeti to deal with... and yes the brakes are a real pain on a few of them requiring regular bleeding on the trail... not hard to do but really painful.
2018 brakes were worse then 2019... but nothing seemed to be different.
The Service Bulletin with toque specs solved some but very few issues.
We noticed that that the brake pistons often moved with asymmetric pressure (one side moved the other barely). O-rings leaking air but not fluid would explain this.
Your insight that the issue is the O ring will be extremely helpful... Time to order a bunch of O-rings and swap them out... repeat until no duds remain.
Excellent information delivered without the usual long winded whinging and complaining ... thank you.

yeti is aware of this widespread issue and working on a fix
I'm the wrench for our group and my buddies new 18 yeti has to be bleed every ride so far.

Mine doing it as well.
Clamp your brake lever tight overnight and theyre solid again the next am.
Not sure if a std o-ring can handle brake fluid. If anyone figures out a fix ide sure like to know. Tks

My Yeti dealer says he has never heard of this being an issue. Except from me, I'm the only complainer.

must have been a caterpillar dealer in a past life..
