ABSTRACT:
The hydraulic disc brake actuator for a trailer includes a first connector for securing the actuator to a towed vehicle; a second connector for securing the actuator to a towing vehicle; and a force multiplying parallel linkage apparatus connected between the first and second connectors for actuating a brake master cylinder. The master cylinder has a body portion and a plunger portion, the body portion being connected to one of the first or second connectors and the plunger portion being connected to the force multiplying apparatus such that the magnitude of force applied to the master cylinder is greater than the magnitude of force tending to move the first connector relative to the second connector. The parallel linkage supports and lifts the tongue weight of the trailer to dissipate energy, and to prevent binding between the connectors when they shift from a towing position to a braking position.
