I just went to O-ring store and show them what I need even though they didn't have exactly the same size. Eventually didn't make a success. The genuine o-ring size is d7.5 D9.5 W1 by my measurement in case you need to know.
@@drivehigh2002 hi i just fixed my shifter by just checking and cleaning the o-ring and the inside of the piston chamber. I think its a mistake when you apply grease.
@@henryponiovasquez Hi Tom, this is something very important to a lot of us out there .We would appreciate some more info of how you did it . Many thanks.
Hi where did you buy the o-ring? I have the same problem.
Hi..how did u push the piston out? Is the o ring the same size as bleed cap o ring?
Hello! Did you have to remove all of the oil in the system before taking out the master cylinder?
No, I didn't, because I wanted to do a quick fix and pop it back to see if it was fixed.
哥這超屌 看到尾巴我笑了 哈哈哈 回歸正題 我也遇到這個狀況 結果旁邊那個diaphragm 一直起泡泡 您有見解嗎 我的變把是有撞傷
我的R7020 也是側漏，結果是diaphragm破了。可以參考

有提到零件型號。
Is this also possible with an di2 shifter (ST-R8070)
I have only seen once a broken diaphram on a di2 shifter causing oil leak, which is different to the issue here.

@@henryponiovasquez That's awesome! Great to hear you fix it, maybe I have done too much.

@@drivehigh2002 Hi Jen. Is this the only o-ring you have tested ? did you managed to fix this later ?
Thanks.
