Clutch Slave Cylinder Failure

[apowell@ezlink.com]

Mike Arman commented about frequent failure of clutch slave 
cylinders in his car.  Fom his text, it's clear that this unit uses 
brake fluid - and he commented at length about DOT3 making it 
leak and DOT4 helping it to last longer.

Mike, based on my experiences with the Datsun 240/280.280ZX 
series, I recommend using silicone brake fluid in the clutch 
assemblies.  No problems with moisture accumulation (which 
seems to be the Datsun's Achilles heel) and we all know the 
preservative qualities of silicone for seals.  Although it has a lower 
boiling point than the latest conventional DOT brake fluids, that's 
not an issue in the clutch assembly because you don't work it hard 
enough to elevate the temp to the point that this become an issue.

Can't say with conviction that this will solve Audi clutch cylinder 
problems -but it sure took care of those in my 280ZXT!  And all it 
costs you is a bottle of brake fluid and some clutch draining and 
bleeding.
