Note: Do not power wash the Hydrastar actuator or take it through a commercial car wash. High-pressure water may damage the seals on the actuator.
The Hydrastar electric-over-hydraulic trailer brake actuator applies pressure to your trailer's hydraulic brake system in response to the electrical signals sent from your in-cab brake controller. As a result, your trailer's hydraulic brakes will be activated every time you apply the brakes in your vehicle or press the manual override on your controller. This setup is ideal for boat trailers because you will get responsive hydraulic braking, which you control conveniently from inside your vehicle with your electric brake controller.
Hydrastar Electric-Over-Hydraulic Actuator vs. Standard Surge Brake Actuators
With the Hydrastar electric-over-hydraulic actuator, you can get all the benefits of towing with an electric brake controller while using hydraulic brakes. Because this actuator will activate according to the settings you have chosen for your brake controller (sold separately), you will have more control over when and how your trailer brakes engage. Depending on the features of your brake controller, you may be able to control both the rate and intensity with which your trailer's brakes activate. You can also use the manual override on your brake controller, which allows you to engage the trailer brakes without having to apply the brakes in your vehicle. And perhaps most impressive, if you have a proportional brake controller, your brakes will be activated with an intensity that matches the braking speed and power of your rig.
This pump-and-motor-based system increases response time compared with traditional actuators because the trailer brakes are triggered when you apply the brakes in the tow vehicle, as opposed to when the trailer pushes against the hitch ball. This not only gives you faster, more efficient braking, but it also eliminates the pushing sensation that occurs in setups that use standard surge brake actuators.
Hydrastar actuators are also beneficial because, unlike standard surge couplers, they allow you to activate your brakes when reversing down an incline, such as a boat ramp. Having the ability to brake in reverse gives you more control and prevents wear on your tow vehicle.
Hydrastar Installation
This Hydrastar electric-over-hydraulic brake actuator will give you years of trailer-stopping performance. The actuator mounts on your trailer's frame with the included hardware. Then it splices into the trailer's wiring and connects to your hydraulic brake lines from the 3/16" female port. Lines and fittings are sold separately.

Hello, everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the Hydrastar Electric Over Hydraulic Actuator for drum brakes. Has a 32 ounce capacity and a 1,000 psi output pressure. Now, with a huge reservoir that holds a full quart of fluid, this actuator's perfect for your big multi-axle camper. Application, will fit single tandem and triple axle trailers with drum brakes. It is an electric over hydraulic brake actuator, so it does activate your trailer's hydraulic drum brakes when you apply the brakes in your tow vehicle.
A brake controller is required to send that signal from the tow vehicle to the actuator when your brakes are applied. The brake controllers we do sell separately. Also, you'll need a 7-way trailer connector, and that's needed to transmit the signal from the brake controller. This will give you improved functionality when compared with surge brake couplers, 'cause it'll give you a faster response time. Your trailer brakes are triggered when you apply the brakes in the tow vehicle as opposed to when the trailer pushes against the hitch ball.
There's no need to manually lock out your brakes when you back up, and the trailer brakes can be intentionally activated when you reverse. The manual override on the brake controller can be activated, so that you can engage the trailer brakes without having to apply your vehicle brakes. As we mentioned, this has a huge reservoir. It's great for trailers with long brake lines that need high volumes and brake fluid. As we mentioned, this has a fluid capacity of 32 ounces.
Right up at the top here, you'll notice it is a translucent tank, and that lets you check the fluid level at a glance. Now, it does require DOT 3 or DOT 4 brake fluid. It is not included, you would have to supply that. They do use an electronic proportional pressure valve to ensure that the braking is smooth and effective. Right up at the top here, has a built-in bleeder screw, which will let you easily flush out air of the brake lines.
And right down here is where your brake line attaches. As you can see, this is a nice, durable, extruded aluminum construction, provides corrosion resistance. And it is compatible with any standard five amp hour battery breakaway. This unit will install on your trailer frame, connects to your trailer's wiring and the hydraulic brake line. The brake lines we do sell separately. This part is made in the USA. Power for this is 12 volt DC power. The maximum output pressure is 1,000 psi. It is DOT, Department of Transportation compliant. We mentioned it connects to your trailer wiring. And if we pull out our wires here just to show you, there's four wires. And basically, the black one is for your 12 volt power, the blue one is for your brake controller, yellow is for your breakaway, and the white is for the ground. And the last thing, just give you the mentions on this. If we measure the length, if you noticed at the bottom, it has this mounting tabs. So we're gonna measure from the edge of the mounting tab to the edge of the mounting tab. So if we do that, that's gonna be right at 11 3/4 inches long. The width, the widest point, right at three inches wide. And the height from the bottom to the top of the cap here is gonna be right at 10 3/4 inches tall. But that should do it for a look at this Hydrastar Electric Over Hydraulic Actuator for drum brakes.
