Abstract
A fluid pressure responsive brake system for the trailer of a vehicle. The brake system includes a trailer supply circuit, which can be connected with the supply circuit of the tractor and which can be connected with an electrical trailer brake circuit, which is connected with the brake system emitting electrical brake signals and the electrical feed of the tractor. There is an electro-fluidic switching apparatus with an OR circuit, by means of which and in connection with an electronic control unit of the trailer, the brakes of the trailer are set if the trailer brake system is separated from the supply circuit of the tractor and/or from the electrical brake signals or the power supply of the tractor.
