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.

This is the BEST way to convert your surge brakes to electric. Pared perfectly with my 2014 F150 with the electric trailer brake option. Controls work great and this specific 1k PSI version easily handles my trailer and 21' SeaRay boat.
This is an excellent device. After years of towing camping trailers with electric brakes, I got used to the control that provided: a bit of sway starts and all you have to do is activate the trailer brakes alone via the controller and everything settles down....so in comparison the surge brakes on my new 6000 lb boat trailer outfit were not doing it for me. Plus-- no trailer braking while backing down a slippery boat ramp?? So this was such a great solution. I can back down the boat ramp with full control at all times, and can adjust braking on the road with the boost and gain functions of my P3. Oh one thing- not all controllers work with this! Had to switch my Prodigy RF for a P3. I had the trailer brake system installed by my mechanic but I did the wiring myself. The light and brake connection outputs from my VW Touareg factory 7-way did not match the instruction's colour diagram but I figured it out eventually. Probably just a VW thing.
Most of the items in this package were top shelf! The one exception is the 7 way harness supplied. The harness was not wired following standard the color code for trailer lighting. The red and yellow wires were reversed and the brown and green wires were reversed in this harness. This error consumed quite a lot of time troubleshooting the trailer lights until I wired the trailer and performed a plug pins to wire check and found the errors.

It works fine after I discovered the color coding on the pig tail was not correct.
I bought this as I was replacing a worn out surge brake set up.
I went with the electric hydraulic set up (after discussing options with Ricky S. Thanks!) as I wanted to address two issues: 1) better braking for an 8,500lb boat/trailer configuration; and 2) be able to use the Reese SC Weight Distribution w Sway Control set up with the Reese Pole-Tongue Adapter for Weight Distribution Systems.
This is an amazing upgrade! Backing up is now easy, I have brakes loading/unloading the boat on the ramp now, and vehicle stops better without the "pushed around" feeling that I used to get from the surge brakes. Additionally, it allowed me to make my vehicle safer by using the WD hitch as recommended by the manufacturer.
While this was a more expensive option that a straight surge brake replacement, it was probably the best few hundred dollars I've ever spent!
Good looking product. Everything was included as I expected, the length of the truck plug whip is a good length for a universal kit. All the colors for wiring in the box are also labeled, that was nice to see. That will help with installation time. This is being installed on a boat trailer with a swing away hitch so the hitch neck is short but it looks like everything will fit without getting it all wet.
Put the product on an ambulance simulator used in training EMS personell. It was easy to install and worked as expected. We would order again if need came up>

We installed the brake system on a customers trailer...they are happy with the system and we have not had any issues to where the trailer would come back for service. We would use the product again if needed.
Do you have a question about this Brake Actuator?

Continues to be brilliant. Such a secure feeling backing down ramps knowing the trailer is being braked even in reverse. Have now moved it to an Audi Q7 - plug and play, the connector was the same as the Touareg
