Method and apparatus for determining the boiling point of brake fluids

Abstract

Abstract In order to determine the boiling point of a liquid, especially a nonaqueous one such as a brake fluid, a device suspended in a body of that liquid-e.g. in a reservoir supplying fluid to a brake cylinder-forms a narrow chamber which is downwardly open and upwardly closed and which contains means for heating the liquid in that chamber and measuring its temperature; the two functions can be simultaneously performed by a thermistor. When the boiling point is reached and the liquid in the chamber is vaporized, a lessening of the heat conduction to the main body of liquid results in a steep rise in temperature; the boiling point marked by this event can be read on a meter and/or qualitatively indicated by differently colored lights, for example. An excessive temperature rise early in the test will also show an unduly low liquid level in the reservoir.
