Abstract
A brake malfunction warning and indicating system for use with a brake system of an automotive vehicle, comprising a brake warning switch rendered conductive when a brake pedal is depressed with the braking oil pressure being at an abnormal level and also when the brake pedal is released, a self-maintaining circuit connected to said brake warning switch and rendered conductive, only when said brake warning switch is conductive, for self-maintaining its conductive condition, and an indicating circuit connected to said self-maintaining circuit and rendered conductive, when said self-maintaining circuit is conductive, for turning on a brake malfunction indicating lamp. Thus, the indicating lamp will continue lighting, while the braking oil pressure is at an abnormal level, until it is restored to a normal level.
