Anodized aluminum electric-hydraulic actuator lets you use your brake controller (sold separately) to activate your trailer's hydraulic drum brakes. Vented end plate releases heat. Includes hardware. Hydraulic lines and breakaway 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 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.
Durable Construction
Just like other Hydrastar electric-over-hydraulic actuator models, this system is built of extruded anodized aluminum for excellent corrosion resistance. In addition, the weathertight seals protect internal components from the elements.
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.
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.

Anodized aluminum electric-hydraulic actuator lets you use your brake controller (sold separately) to activate your trailer's hydraulic drum brakes. Vented end plate releases heat. Includes hardware. Hydraulic lines and breakaway sold separately.
the unit itself is easy to install and is working great,I bought it last March/April and unpackaged it and installed on during off season in Dec. and noticed the fill cap broken during shipping to Canada, etrailer said they would not replace the $XX.00 cap because too much time has passsed,so un package ASAP.
Otherwise there prices are great.
Cap was broke when I opened the box
The product was great. Very satisfied.
I am super happy with my replacement of the electric brakes on my camping trailer with this Electric Over Hydraulic Actuator and Hydraulic Brakes. It works SO much better than electric brakes ever did. I feel much safer towing the trailer now.
Nice piece, look great and easy to install. Delivered fast.

Juste great, as new
I need to know how I can connect this 4 color wires on hydrastar actuator to my kaufman trailer??

Thank you for your review. The Hydrastar Actuator will wire to the breakaway kit of the Kaufman trailer and the electric brake controller in the tow vehicle. I have attached an electrical diagram for a visual of how the wires attach. You should already have a brake controller for the electric brakes but if you have an OEM brake controller it will need to be replaced. I recommend the Prodigy P3 90195 which is one of our most popular brake controller options. If you need a breakaway kit, I recommend Hopkins engager break away kit part 20099 because of its convenient push to test button and built in charger.
Loved going from Surge brakes to Electric, made a HUGE difference! Make sure to follow the directions, the color coding is not US standard when it comes to green, yellow, brown. BUt works great and easy to bleed.
Adapters to fit brake lines are hard to find … they should include the fittings
awesome service, parts were on time, hassle free!! Thank You Bunches!!!
Very knowledgeable about the product, quick delivery and product looks good is described.
Great price and service
Works great this is the best brand I have had I know have 2 of these.
