[6pack] Silicone Fluid

[Dombey, John R.]

Eric,

I've been running the purple stuff since early 2003 with no issues that
I can attribute to the fluid.  The clutch master wept just a little from
day one, but it was a unit that I had rebuilt during my restoration, so
I suspect either marginal seals or poor workmanship on my part.  I
replaced it with a new one last year and everything has been fine since.
I too was worried about paint damage with DOT 3, and at the time the
paint was fresh and shiny...

OTOH, Greg at BPNW is pretty knowledgeable - he's never steered me
wrong, and has saved my bacon a couple of times.  The poor lubrication
comment seems strange - isn't silicone inherently slippery stuff?

Looking for information on issues surrounding use of DOT 5 silicone
fluid for
brakes and clutch. I have been running for 4 years since I rebuilt my
TR6 and
only recently encountered some problems with my clutch binding during
engagement. I thought the clutch master might be at issue and found some
light
scoring  in two places on the cylinder bore. When I spoke to British
Parts NW
they indicated that use of silicone fluid voids the warranty on master
cylinders due to degradation of the aluminum body and poor lubrication
characteristics. What is the recommendation on this?
