Last week I completed a driving tour in our BJ8. It was a great tour and ev=
erything ran well except for one thing.  4 or 5 times, when I used the clut=
ch, the clutch master cylinder bypassed. The rest of the time it worked wel=
l. As I don't want to be caught without a clutch at a later date I am chang=
ing the clutch master cylinder. I have received a replacement and am prepar=
ing to install it.
On the box is a quick summary of the bleeding procedure under a warning - "=
Using Silicon Brake fluid will void warranty". I have used silicon fluid fo=
r well over 10 tears and never experienced any problems with it and have ne=
ver seen or heard of this type of warning before. I have never heard of any=
 destructive qualities of Silicon fluid.
My question is - does anyone have any idea what it is about.
For me to change to Dot4 fluid is quite a big deal as I would be changing o=
ut the clutch as well as the brake system seeing as they share a common res=
ervoir.
I'd appreciate any comments on the warning.

What brand master cylinder did you get? Not what supplier did you buy it fr=
om. I would suggest contacting the manufacturer & ask what their reason is =
for the warning message.=C2=A0I read somewhere that all seals are designed/=
intended to swell when in contact with any brake fluid. A few years ago I p=
ut a new seal in DOT4 & a new seal in DOT 5 fluid & after a couple of month=
s, I could not measure any difference in their sizes.=C2=A0
By "bypassed" do you mean the peddle went to the floor? It that is the case=
 & there are no leaks evident, It sounds like your "check valve" in the mas=
ter cylinder is intermittingly malfunctioning. Maybe there is debris in the=
 master cylinder or some other cause. You might try simply replacing the se=
als including the check valve assembly.=C2=A0Gary Hodson=C2=A0
