Brake fluid

I suggest not using silicone-based (DOT 5) fluid. Its non-hygroscopic nature (i.e., its not absorbing water) is not definitely a good thing. Moisture gets into the brake hydraulic system -- it will happen with normal usage and/or changes in ambient temperature and humidity. Ordinary brake fluid is designed to absorb and assimilate a fair amount of moisture without causing substantial corrosion problems. With silicone fluid, the water will accumulate in slugs at the lowest points of the system...and stay there, where it will aggressively corrode whatever it's touching. This is not an improvement.

Furthermore, it is difficult to get all the air out of silicone brake fluid, so it is difficult to get a good, firm pedal.

There is an enormous range of conventional non-silicone brake fluids on the market. You can get whatever properties you want (e.g., high boiling point) without having to go to a silicone-based fluid.

And as if that weren't enough, the cost and effort difference between regular and silicone fluid is such that you can flush the system with conventional fluid every two years or so (which is about the right interval) for a long time before you equal the cost of just one silicone fluid changeover.

Shop carefully. All silicone fluid is "DOT 5". The highest spec category for non-silicone fluids is "DOT 5.1".

DOT 3 (original fill), DOT 4, and DOT 5.1 fluids are all intermixable.

DOT 5 (silicone fluid) cannot be mixed with DOT 3, 4, or 5.1.

Really, it is not necessary to spend big money on exotic brake fluids. Use a good brand of DOT 3 or DOT 4 (I have tended to use Castrol LMA DOT 4 when I can find it) and flush the system every two years and you'll be in fine shape.
