ABSTRACT:
A monitoring system for a vehicle's air-brakes in which the push-rod extending from the brake chamber engages an electrical switch. The electrical switch, if moved to a pre-selected position (indicating that adjustment of the push-rod's connection to the brake is warranted) transmits electrical energy or other such signal to an alarm within the cab of the vehicle where either an auditory alarm is sounded or a warning lamp is illuminated. The monitoring system is operationally checked through the use of several alternative mechanisms. In one such check mechanism, a switch located near the warning lamp, allows the operator to transmit electrical energy to the remote switch located at the push-rod where the electrical energy is transmitted back to the warning lamp. In another check mechanism, a switch located near the warning lamp is used to engage a solenoid which pushes the remote switch into a transmitting position to check the entire monitoring system. In one embodiment of the invention, through the use of flip-flop switches, once the warning lamp has been activated, it remains illuminated so that, when the vehicle is returned to the garage, the mechanic is easily able to determine if the air-brakes need to be adjusted.
