Brake System Academy 2 0 brake fluid

On another note, that explains why I saw tubes along the walls of my cars rear trunk

Why does hydraulic oil get moist because the brake system is closed? Where does moisture come in?

[@graemeryder506]

Through the pores in the rubber brake hoses. Water molecules are smaller than brake fluid molecules

[@graemeryder506]

Glycol based fluids are hygroscopic and pull the moisture in.

What happens if water pour in brake fluid accediantly

[@jkxss]

You should do a brake flush since you will have water in the system that will boil off and leave air in your system. This will make your pedal go down without providing much brake pressure because air is compressible and doesn't provide resistance like brake fluid does. You would still have brakes, but your pedal feel would be mushy which would potentially be dangerous because you wouldn't have great breaking pressure. Stopping distance depends on your tire grip, but most "non-car enthusiasts" do not flush their brake fluid (dealerships may even just top off master cylinder instead of proper bleeding) so you should probably do it anyways.
