Abstract
A brake clearing system useful for clearing mechanical components of one or more brake units provided on a freight trailer having an air storage reservoir. The system includes a flow controller, at least one delivery hose, and at least one discharge device. The flow controller is fluidly between the air storage reservoir and the auxiliary tank. The delivery hose is fluidly connected to an outlet of the flow controller and delivers pressurized air to the discharge device. The discharge device, in turn, is configured to direct pressurized air at components of one of the brake units. The flow controller can include an inflow control unit, an auxiliary tank, and an outflow control unit. In related embodiments, the auxiliary tank can include a heater.
