S03E2, Captain's Bridge on Death Heat:

- captain!
- what's that, solder?
- we see a brake fluid molecule!
- locate and destroy!
- sir, brake fluid molecule is destroyed! Sir.
- good job, solder. Keep on looking since there's darn plenty of them around!

It's amazing to see folks kinda doing their job while they absolutely do not know the matter. One can sell stereo amplifiers and have no clue about channel separation or slew rate...

Brake fluid is just an actuating medium that transmits the force applied to MC piston to pistons in the calipers. The only requirement to this medium is that it must be incompressible within the whole temperature range it's subject to. All the fluids are incompressible while any gases (incl steam) are compressible. Pre-DOT5 brake fluids are based on ethylene glycol and DOT5 fluids go with silicone base and thus they go boiling at very (indeed, VERY) high temperatures. And the only cause for them to lower that boiling-point is added moisture.

Whatever (reasonable; we're not talking about nuclear plant) heat is applied to ethylene glycol or silicone - it doesn't kill'em (change molecular skeleton). Brake fluids must be changed at least every two years or 40K miles whatever comes first only cause of the humidity in the air that goes into the brake fluid reservoir. If a hydraulic brake system could be designed to be air-tight (incl no air in the BFR) then there'll still be a need for brake fluid change (commercially available fluids are not 100% clean and do contain some admixtures that cause brake line, cylinder and piston corrosion) but twice/thrice less frequently.
