The papers deals with the dynamic stability of a broke shoe under pulsating frictional forces. A lining part of brake systems is assumed as a distributed spring, and the supported elements of a shoe is assumed as translational springs for a constant distributed frictional force and pulsating frictional force. Govering equations are derived by the extended Hamilton's principle, and numerical results are calculated by finite element method. The critical distributed frictional force and instability regions were investigated for the change of distributed spring constants. translational spring constants.
