This work investigates squeal propensity problem arising during normal braking. Narrative of this work is suggesting complex eigenvalues method to found out tendency of squeal propensity. The work also provides a brief introduction of complex eigenvalues method and literature review of the problem, which shows study done in this field by other investigators. Frequencies and instability measurements were calculated. Afterward standard deviations were plot to found out whether squeal will be reduced or amplified, within chosen parameters. The results illustrated that by increasing the coefficient of friction the instability measurement will increase and reduce when hydraulic pressure increased.

Keywords: complex eigenvalues, squeal propensity, standard deviation, brake system, squeal reduction, instability measurements
