Abstract
Circuito de aviso para frenos de vehículos a motor, cuyo vehículo tiene medios para poner en funcionamiento el motor, teniendo el circuito de los frenos una fuente primaria de fluido a presión de accionamiento de los frenos, movida por el motor, una fuente auxiliar de fluido a presión de accionamiento de los frenos, y un dispositivo de relé para accionar la fuente auxiliar al fallar la fuente primaria, caracterizado porque comprenden medios de circuito acoplados a los medios de accionamiento del motor y al dispositivo de relé para generar una señal de aviso en respuesta a una conducción de circuito abierto del dispositivo de relé cuando el motor está en marcha.
