I've used silicone brake fluid since 1982 in various cars, over 10
years for the MG, no problems, no leaks. No, I didn't replace every
rubber seal within 50 feet. In fact, the only components I replaced
were the previously leaking rear wheel cylinders. I have replaced
various components , such as the master cylinder, which wore out. But
then, it was 20 years old anyway. I also autocross the car, and, yes,
I bleed it every year before it goes on the road. which, I agree with
the previous poster that is a much-neglected maintenance item. It is
on the maintaince schedule for BMWs & SAABs, among others. I also use
it in the BMW (that has 3 bleed nipples on each front caliper,
yikes!), that still has some rubber in the brake system from the DOT 3
days. No problems. YMMV.
