The Brake Inspector® electronic in-cab display provides accurate brake stroke travel indication in real time in the cab of a truck or bus. The display shows the status of four, six, or eight brake chambers depending on the gauge model that the truck or bus is equipped with. Each time the air brakes are applied the gauge will simultaneously show the brake stroke status of each brake chamber utilizing a series of colored light emitting diodes (LEDS). Each chamber that is being monitored has two corresponding LED positions on the gauge.

The last brake application is stored in memory enabling the driver or maintenance staff to recall the status of the air brakes at any time simply by pushing a single button.

The LEDS will also show the status of each spring brake application that is made when the emergency brake (spring brake) is applied. If the spring brake application is the last brake application it will be the one stored in memory.

The driver or maintenance staff can individually check the status of each brake chamber by pushing the status indicator button and cycling through each chamber position starting from the front left chamber. The LED beside the brake chamber that is being inspected will light up along with the row of four LEDS on top of the gauge.

These four LEDS two Green, one Yellow and one Red depict the complete brake stroke travel of a particular chamber.

The internationally accepted colored-code standard, Green for "go", Yellow for "caution" and Red for "stop" has been used to represent air brake stroke travel.
