Arrives before Christmas 
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.

A+ fast service
Quick delivery, great service
THE PRODUCT I NEEDED AT A GREAT PRICE WITH A FAST DELIVERY
Perfect! Exactly what we needed to complete the job.
Service was exceptional as for the product is what is, replaced the same that was in service for 6 years, should have lasted a lot longer
all worked out great
I was pleased with my purchase and the timely manner in which it arrived. The packaging was damaged so I was skeptical whether the product would be as well.
SO FAR IS WORKING GOOD STOP TRAILER NICE AND SMOOTH.
The product was exactly as picture, etrailer did an outstanding job expediting this order, got the product the next day .
I’ve been installing these HBA - 10 actuators on new trailers for a year now and they have been working great.
Received our order today. It was delivered quickly and in great condition. Obviously we haven't had a chance to install nor use it yet so I can't speak to the review of that. But I will say that Cailee and etrailer did a fantastic job of getting what we needed to us asap! Thank you Cailee!
Night and day difference from the useless surge brakes on my boat trailer.
It's been a good kit so far!! Had all the supplies I needed when installing it on my 30' float. Worked good on my Alko/kelsey hayes brake kit.
awesome product, I have installed 4 more for customers,, works great, very easy to install and do away with surge brakes,, its a 5 out of 5 ,,, ill be buying more
I just got it put on the trailer so really haven't had a chance to try it .
The part went on the 3 horse living quarters trailer which I hope to pull later today. The brakes activated properly, bleeding process was certainly a two man operation and took quite a bit of time.
Work Great Fast Shipping
Thank you for the prompt delivery, three days quicker than expected
