EFFECT OF WATER ON HYDRAULIC BRAKE FLUID

Abstract

A study was made to determine the effect of absorbed moisture on the physical and chemical characteristics of polar type hydraulic brake fluids. Specific studies were carried out on the effect of moisture on equilibrium boiling point, flash point, cold temperature viscosity, oxidation stability, and effect on rubber with several polar brake fluids of varying chemical composition. Moisture produced the following effects - a. Boiling points are lowered in all brake fluids - drastically in so-called 'high boiling' fluids. b. Flash points are increased. c. Cold temperature viscosities are usually increased. d. The stability of the brake fluid toward oxidation is decreased. e. Rubber swelling and softening is decreased.
