PURPOSE: To permit a driver to be relieved and secure the safety for the driver by allowing an-alarm to be generated by a detection signal from a temperature detector arranged on a brake when the brake temperature rises over a prescribed value.
CONSTITUTION: A temperature detector 20 is fixed onto the piston head 13H of a disc brake 10, and further connected to an alarm device 30 through a lead wire 21. Said alarm device 30 is constituted of an alarm controlling circuit 31, sound generator 32, and an alarm display device 33. Said alarm controlling circuit 30 receives a signal 100 from the temperature detector 20, and transmits an emergency alarm signal, when the detection temperature To rises over a temperature lower by a prescribed value α than a temperature Tu at which the vapour-lock phenomenon is generated, and transmits an anomally alarm signal, when the detection temperature is lower by a prescribed value α or more and is over a temperature lower by a prescribed value β (which is larger than α) than the temperature Tu.
