A hydraulic brake coupling that connects a vehicle hydraulic brake system of a vehicle to a trailer hydraulic brake system of a trailer. The hydraulic brake coupling includes a vehicle coupler that is fluidly connected to the vehicle hydraulic brake system, and a trailer coupler that is fluidly connected to the trailer brake system. The vehicle coupler and the trailer coupler are designed to make a fluid tight connection. When the vehicle coupler is coupled to the trailer coupler, activating the vehicle hydraulic brake system causes fluid pressure to pass from the vehicle brake system, through the vehicle coupler and the trailer coupler to the trailer brake system.
