A device and method for providing a warning to an operator of a truck/tractor and trailer unit of a potential loss or reduction of brakes. The invention provides a pressure differential sensor (12) which bridges between an air supply line (13, 16) to the spring brakes (1 7) of a truck/tractor and an air supply line (14) to the trailer. An audible and/or visual warning device (31 , 33) coupled to the sensor (1 2) is activated upon a differential between the pressures in the respective supply lines (1 3, 16 and 14) being sensed.
L~invention concerne un dispositif et un procédé destinés à alerter un conducteur d'un camion/gros porteur d~une perte ou réduction potentielle du freinage. L~invention procure un capteur de différence de pression (12) reliant un circuit d'alimentation en air (13, 16) des freins à ressort (17) d'un camion/gros porteur et un circuit d'alimentation en air (14) de la remorque. Un dispositif d~alerte sonore et/ou visuelle (31, 33) couplé au capteur (12) est actionné en présence d~une différence de pression entre les pressions des circuits d~alimentation respectifs (13, 16 et 14).
