[Fot] silicone brake fluid

[Steve Yott]

>From what I have seen nearly all of the new built cylinders will carry that
warning.  I think it's more of an insurance disclaimer since silicone is not
DOT approved for use in street cars.  I too have used it in my cars and
setup many others with silicone and what I have found in the past couple of
years is that the seals don't have a sharp enough edge to hold the silicone!
As we know this stuff is very slippery and if the seal edge is just slightly
rounded the silicone will seep by resulting in loss and a soft pedal.  I
remember in years gone by that the seals one could buy had rather sharp
sealing edges and the seals today are definitely more rounded.  It also
seems that to buy seals alone from auto parts stores is a thing of the past
and not many carry the old box of seals any longer. 

All you can do now is search for seals that will work.

I have been using silicone brake fluid for ever it seems, in the race car
and my street car. !0+ years on the same master cyl, calipers and rear wheel
cyls.  This year I rebuilt my master cyl., front calipers and new rear wheel
cyl. Please don't ask me why! Poor brakes by the end of one race. So I
ordered a new master cyl.,which I recieved yesterday. Open the box and
included is a note, " use of silicone fluid voids warranty". OK the
question, are the newer seals not compatable with silicone?
