Subject: Re: Clutch master problem (I think)


if you are power bleeding the system it might be that there is blockage in the line, but reading your question, you don't say if you are trying the clutch pedal at the same time as the bleed. i know from recent bitter experience that when my 9000 clutch went, it sounds very similar to the problems you are experiencing. if the 9000 system was designed from a previous version (eg a 99 system), you might want to try this first before you get hammered for an expensive repair. see the link below & have a look near the bottom of the page, it seems to say that you need to try the clutch pedal during bleeding, http://www.thesaabsite.com/900old/c900clutchrepair.htm hth kds :-) "Dave Hinz" <DaveHinznospamcop.net> wrote in message news:2v9rsfF2f73k3U2nospamberlin.de... > On Mon, 08 Nov 2004 17:12:06 +0000, Grunff <grunffnospam.com> wrote: > > Dave Hinz wrote: > > > >> Questions: does this sound like master cylinder problems as I think? > > > > Very likely. > > Yes, with a "yes, but".
