Paper deals with development of an effective numerical model of a extended pin-on-disc experimental model. This model is designed to simulate thermo-mechanical behavior of the simplified braking system focusing on dissipation of energy, evolution of temperature distribution and evaluation of dynamic instability of the system over time. Mathematical description of the system is done using FEA approach. Commonly used complex Eigen value analysis is extended with thermo-mechanical influence and varying contact distribution to predict system dynamical instability. Influence of generated heat and contact distribution on the system dynamical instability is studied. Model's credibility is proved through a series of experiments on an experimental test bench.
