Vented, marine-grade aluminum electric-hydraulic actuator lets you use your brake controller (sold separately) to activate your trailer's hydraulic drum brakes. Includes wiring, 7-way harness, and breakaway. Brake lines sold separately.

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 stainless steel hardware. The included 7-pole junction box with color-coded studs makes it simple to splice into your trailer's wiring and to connect the provided 7-way trailer connector. Once the actuator is correctly wired, you can connect your trailer's hydraulic brake lines to the 3/16" female port. Lines and fittings are sold separately.
Durable, Marine-Grade Construction
The Hydrastar Marine actuator is ideal for use on boat trailers. Just like other Hydrastar electric-over-hydraulic actuator models, this system is built of extruded anodized aluminum for superior corrosion resistance. The weathertight seals protect internal components from the elements. The Hydrastar Marine actuator also features marine-grade gaskets and stainless steel hardware that won't rust. These extra features make it perfect for marine applications.
This actuator also has a vented end plate that releases pressure, moisture, and heat to help prevent any internal damage. Unlike models that are unable to release heat and pressure, this vented actuator can be safely mounted inside of a compartment on your trailer. As a result, this actuator is great for gooseneck and fifth-wheel trailers where finding space on the tongue can be nearly impossible.
Breakaway Kit
Required by law in most states, a breakaway system will activate your trailer's brakes in the unlikely event that your trailer disconnects from your tow vehicle. This kit wires to the included battery and to the Hydrastar actuator. If your trailer separates from your tow vehicle, the breakaway kit signals the actuator to apply the brakes.
Brake Controller Compatibility
Not all electric trailer brake controllers will work with this electric-over-hydraulic brake actuator. See the following table to determine compatibility with common models of brake controllers. For best performance, it is recommended that you use an aftermarket electric brake controller rather than an OEM factory-installed controller.

Vented, marine-grade aluminum electric-hydraulic actuator lets you use your brake controller (sold separately) to activate your trailer's hydraulic drum brakes. Includes wiring, 7-way harness, and breakaway. Brake lines sold separately.hydrastar system has been the answer as we can back down the boat ramp with our tri-axle being able to have braking power in reverse. The product is every thing it was said to be and can not say enough about the system to our friends. We installed six new brakes and kit lines all from etrailer.com. The staff was very helpful, and would deal with them again.
Awesome product works way better than my surge brakes, the terminal connection box made wiring a breeze! Awesome customer support from E trailer.com to resolve a cracked hydraulic cap!
This is the best brake setup I have seen or used on a trailer!!!
And I have 3 other trailers with electric brakes!!!
If I ever have a problem with them I will replace with the Hydrastar unit!!!
Just finished installing have not took it out yet
Easy to install had an issue with my controller not working.
once I updated my controller it worked good.
Not sure how to recharge the battery will need to look into that

The breakaway system battery should be getting a trickle or maintenance charge from the 12-volt feed on your 7-way trailer connector. Check how the battery and system is wired up against the diagram above, you might also want to test the battery as well and replace it if necessary.

Product works fine, I exercise brakes monthly, keep battery charged, ect. Don’t use trailer often as keep boat on lift. Insurance coverage requires alternate means of moving boat in hurricane prone areas. Yearly I do replace brake fluid.
Product came as described and works. Time will tell longevity, but it does what it's suppose to.
Prompt service, arrived on time.

The only change I should have done was to use Disc brakes instead of Drums! The Hydrastar is still the best!
