Abstract
A brake system for a towed and towing vehicle combination allowing for application of the brakes of the towed vehicle in proportion to application of the brakes of the towing vehicle. The combination utilizes a signal from the towing vehicle to generate a proportional braking signal in the towed vehicle. In particular, the towed vehicle braking system includes a proportional relief valve that controls the braking pressure on the towed vehicle in response to an electrical signal from the towing vehicle. The system utilizes a control program that signals a power unit in operable communication with the towed vehicle brakes to operate at full power for a first period of time and at a reduced power for a second period of time.
