Trailer Brake Lever

The trailer brake lever is used to apply the trailer service brakes without applying the truck or tractor service brakes. It is usually mounted on the right-hand control panel. Move the lever down to apply the trailer brakes; move the lever up to release the trailer brakes. The lever will automatically return to the up position when it is released. See Fig.. The lever can be partially or fully applied, but in any partially on position it will be overridden by a full application of the service brake pedal.
