ABSTRACT:
A trailer hydraulic brake system is used with a gooseneck trailer and truck combination. The system includes a frame configured to operatively mount the trailer hydraulic brake system on the gooseneck trailer, a brake actuator including a first and second brake actuator member each pivotally attached to the frame, a brake mechanism including a forward and reverse brake mechanism each pivotally coupled to the first brake actuator member, a brake mechanism positioner selectively movable between a forward and reverse position to selectively engage the forward or reverse brake mechanism and a hydraulic master cylinder coupled to the trailer brakes attached to the frame. The hydraulic master cylinder is disposed to engage the second brake actuator member such that when the brake mechanism positioner is in the forward position the forward brake mechanism engages the second brake actuator member whereby as the truck is stopped the first and second brake actuator members pivot in the same direction to actuate the hydraulic master cylinder to brake the gooseneck trailer and such that when the brake mechanism positioner is in the reverse position the reverse brake mechanism engages the second brake actuator member whereby as the truck is stopped the first and second brake actuator members pivot in the opposite direction to actuate the hydraulic master cylinder to brake the gooseneck trailer.
