In brake control based on commands of a plurality of systems, an adjustment valve adjusts fluid supplied from a fluid source to a predetermined pressure to output the pressure-adjusted fluid. An output valve switches opening and closing based on a switching command. A skid detector detects whether a car is skidding or not and notifies a brake controller. The brake controller determines a pressure of fluid output by a control valve and issues a command to solenoid valves provided in the control valve. The brake controller issues a command to a discharge valve to discharge fluid from the discharge valve when a skid is detected. A relay valve adjusts pressure of fluid from the fluid source based on a higher pressure between a pressure of fluid output by the output valve and a pressure of fluid output by the control valve, to output the pressure-adjusted air to a brake cylinder.

A damage detecting device according to one aspect of the present invention comprises a first speed generator, a second speed generator, a first waveform shaping section, a second waveform shaping section, and a determining section. The determining section compares a second rectangular wave shaped by the second waveform shaping section and a first rectangular wave shaped by the first waveform shaping section and, if the first rectangular wave is not output while the second rectangular wave is output, determines that a supporting device for an armature shaft is damaged or worn.
