Im rebuilding my brake master cylinder
have all the new rubber seals.
there are 4 of 1 kind and 1 of another ( similar different lip)
I didn't take notice of what seal went where when I took them off (- over 6 weeks ago)
can anyone tell me where this different seal goes?
my guess is the back end of the top drawing - as it looks a little different to the others (and is in reverse)
haynes manual doesn't show clearly
photo of different seal
here is a few photos of what I have

Re: brake master cylinder rebuild
I think you're right and that would make sense. Since it's a dual circuit M/C you want something separating the two hydraulically. That seal would do that. Your pics didn't come thru, except for the BMW fans one, they just take me to a Google longin screen.

Re: brake master cylinder rebuild
okidoki will give that a shot.
note:
It seems that google photos required the folder to be "shared"- so changed that- hopefully photos show up now
ps all these new seal parts cost me $64 from Perth Brake Parts http://www.perthbrakeparts.com.au

Re: brake master cylinder rebuild
Pics do work now! And kudos to you for actually rebuilding it and not just replacing it. Not difficult but it's becoming a lost art.
