ABSTRACT
Attempt to raise train speed involves application of greater braking power i.e. braking systems rapidly absorbing and dispersing stored heat energy. To maintain high efficiency of braking system in the whole operational process. it is necessary to control the friction set: brake and pad before reaching limit wear particularly of friction pads. The purpose of this article is to present possibility to diagnose the friction set of disc brake by using selected frequency characteristics of vibration signal generated by brake caliper with friction pads. The purpose of this research is to apply vibration signal of pad calipers to assess the wear of friction pads of disc brake during braking with the constant braking power.
