Abstract:
To enable the quality and productivity of transport processes, it is becoming increasingly important to ensure the use of safe and reliable means of transport. The automobile's circuit brake system relies on the incompressibility of brake fluid based on glycol when transmitting power. Fluid operating above its boiling point contains gas which is highly compressible. This paper presents the results of the wet boiling point temperature assessment of the DOT 4 Plus brake fluid used in Volvo cars. By investigation the brake fluid of 48 cars during service inspection, we found that boiling point was within the interval 222–238 ° C, with a 95% probability i.e. higher than the manufacturer specified wet boiling point of 180 ° C. Using infrared spectrometry it was verified that the brake fluid is highly hygroscopic.
