Abstract
A vehicle trailer brake system and method with a hydraulic control line and supplementary line arranged between a towing vehicle and a towed trailer, wherein the trailer braking system is actuated from the towing vehicle by controlling the hydraulic pressure in the control line and the supplementary line. The trailer brake system may be operated to actuate a trailer brake using a trailer-based hydraulic accumulator, to provide for relatively fast response time for the trailer brake.
