PURPOSE:To improve safety and reliability of a system, by returning control to normal brake operation through a fail safe circuit, when an anti-skid control system causes a fault, and interposing and inspection device in said fail safe circuit. CONSTITUTION:If abnormality in a system is detected, a fault detector circuit 4 opens a relay contact 5 to perform return operation to a normal brake. An inspection device A is interposed in a system 12, and for its inspection, if a relay contact 5 is in a fault when a switch 7 is closed, the contact 5 is left as closed, and an EX-OR10 generates output of an H level when a transistor Tr5 is turned off through transistors Tr6, Tr4, after a prescribed time, a control circuit 11 sets a RS-FF12 to turn on a transistor Tr7 with output of Q=H level and turn on a fault lamp 13. |
