The Hydrastar Vented Marine Electric Over Hydraulic Actuator for Drum Brakes delivers instant braking power the moment you press the pedal. With a maximum output pressure of 1,000 psi and an electronic, proportional pressure valve, the brakes engage smoothly and respond faster than surge actuators. Because it reacts to your brake controller instead of trailer pushback, there’s no lag or jerking—just steady, confident braking you can feel right away.
Built from durable extruded anodized aluminum, this actuator is made to handle wet and salty environments without corroding. The marine-grade gasket and stainless steel hardware seal out moisture, while the vented end plate releases pressure, heat, and condensation to protect the internal parts. It can even be mounted inside enclosed compartments where other actuators might overheat or trap water.
Switching from a surge setup to electric over hydraulic doesn’t have to be complicated. The plug-and-play design means no hardwiring—just connect the sealed harness and go. The included Control Adapter Module (CAM) makes it ready to work with factory brake controllers from major truck brands, so compatibility headaches are off the table.
Backing up a trailer or holding it steady on a ramp is easier when you can control your brakes directly. With this actuator, you can intentionally activate the trailer brakes in reverse or use the manual override on your controller without pressing your vehicle’s brake pedal. That added control helps when maneuvering heavy or multi-axle trailers in tight spaces or on slopes.
This unit works with single-, tandem-, or triple-axle trailers using hydraulic drum brakes. Its 12V DC power supply and 3/16" hydraulic port make it straightforward to integrate into existing brake lines. Whether you’re maintaining a boat trailer or replacing an older coupler system, this actuator gives you dependable stopping power with modern electric precision.
