Guy,
It's mentioned in this thread at about post 53. I've heard it other places t=
oo. Manufacturers mentioned that don't like silicone brake fluid are TRW an=
d Delphi. Little fly-by-night operations. =20
http://www.mgexp.com/phorum/read.php?1,3161136,3165850#msg-3165850
Master cylinders are indeed simple pumps - simple pumps with seals and some s=
eals apparently don't like silicone. =20
