Impact of Engine Speed and Time Variations on Temperature and Friction Coefficient of Brake Pads with Remote Monitoring Test Equipments System

Failure of the brake system causes many fatalities that lead to accidents; one of the many causes is Brake Fade. Brake fade mostly caused by braking temperature that exceeds the maximum temperature of the brake lining material, resulting in a decrease in the coefficient of friction (braking power). Therefore, this paper was conducted to analyze the effect of braking temperature on the coefficient of friction, thickness reduction, and braking time. The type of brake used is a disc brake with four brands of brake lining including, AHM brand, Indopart brand, OSK brand. The test method carried out in this research is divided into two methods, the first method is braking from a variety of RPM until a steady condition (the state of the engine stops), and the second method is performing braking cycle test where braking is carried out every 500 RPM with a holding time of 1 minute. Measurement of braking temperature using an Infra-red thermometer and thermocouple which becomes a series of RMS-Brake. Measurement of braking time and brake lining thickness before and after the test is also carried out to determine its effect on braking temperature. As the test results, AHM brand fading at a temperature of 305.9˚C with a friction coefficient of 0.09738, Indopart brand fading at a temperature of 191.1˚C with a friction coefficient of 0.1067, OSK brand fading at a temperature of 203.7˚C with a friction coefficient of 0.109057. In addition, there is also the effect of temperature on the reduction of brake lining thickness, where the AHM brand is the least thickness reduction of 0.1 mm to reach 250.4˚C.
