brake master cylinder rebuild

[garyinwestoz]

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

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.

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

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.
