[s-cars] Clutch Master Cylinder Replacement Procedure

[Mark Turczyn]

Tom-

I just went and ordered a new MC.  When I got home of course I found that I
had a new one on  the shelf since I have always bought  and shelved all of
the suspect parts that anyone talks about on the list.  Interest for me‹the
NOS A90 slave cylinder I have on the self is the same one used in the S6-

So I am not going to rebuild- although if it is cheap I may try it with the
one I take out.   I think the only hesitation I would have is that if it is
a pain to replace the MC I would not like to take a chance that the rebuild
kit may not work.  If I do it this time and it goes fast (in this freezing
weather) I may try it in the future since my bolt is still good on the one
that is leaking‹cannot have too many spares.


I pulled the lower bolster and the plastic heat distribution pipe out last
night to take a look.  Still not sure how you pull the clip on the pin on
the left side.  I guess once you pull out the vacuum switch you have the
room to pull the clip---pretty tight down there.

I got the super glue to tack the clevis pin to a long bolt for the
reinsertion.  Any other tricks come to mind?
