Glycol-ether ( DOT 3 4 and 5.1) brake fluids are hygroscopic (water absorbing) which means they absorb moisture from the atmosphere under normal humidity levels. Non-hygroscopic fluids (e.g. silicone/ DOT 5 and mineral oil based formulations) are hydrophobic and can maintain an acceptable boiling point over the fluid s service life.

Brake fluid is a subtype of hydraulic fluid with high boiling point both when new (specified by the equilibrium boiling point ) and after absorption of water vapor (specified by wet boiling point ). Under the heat of braking both free water and water vapor in a braking system can boil into a compressible vapor resulting in brake failure. [6]
