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.

The controller is still working. It tends to run at a low rate even when we're not braking, but perhaps it's something with our pickup or trailer wiring.
Very good product, it works well with my trailer. Much better than electric drum brakes. Only down fall is I found it is sensitive to voltage spikes. I had a faulty alternator and the control board in the unit burnt out. Somewhat disappointed that replacement parts were not available to repair my current unit. Had to replace that whole unit just for a small circuit board. Great unit otherwise as far as function.
Great product. Low maintenance. Small enough to put in almost any location. I put mine in a side tool box just above my trailer axles. Breaks engage as soon as pedal is engaged.
Been a year, haven't had one issues, very easy install. I went with the hydrastar unit so that i could utilize the brakes from a rear dana 60 axle, from a old service truck that i made into a trailer. The brakes function great. I recommend this unit to any one that is looking for a good solution to trailer braking using hydraulics, this system will also replace a surge brake system and operate much better. etrailer also had great follow up and customer care to see if I was satisfied with the unit which I am!
Still working as it should, no problems with the actuator. Completely satisfied! If only the rest of my braking system were as trouble free!

I am happy with the actuator and how well it is working
I have a tandem axle dump trailer that came with factory hydraulic surge brakes. They worked sporatically at best, were very unpredictable, and eventually stopped working all together.
I installed the hba 10 as well as an electric breakaway switch and eliminated the surge hitch all together.
Works great. Far beyond my expectations.
This company is excellent! They have things I didn’t
even know I needed. Quick turn around time. Couldn’t be easier to get lights, hitches, jacks, brake controls (electric or electric over hydraulic). Been using this company for years and never had a problem.
Perfect! Exactly what we needed to complete the job.
Work Great Fast Shipping

Have Hydrastar HBA12 1200psiG7 on tandem boat trailer. Breakaway activates brakes well but brakes activated thru vehicle do not work.A check of power from vehicle to trailer indicates circuits are all good. Can hear contact noise from inside brake unit but pump doesnt start but thru breakaway activation the pump works well.Have been told the fault is in the Electronic Chip that activates the pump. Is this correct and if so can I purchase that part only? What part number do I order? Appreciate your reply. John B
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.
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 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.
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.
The product was exactly as picture, etrailer did an outstanding job expediting this order, got the product the next day .
SO FAR IS WORKING GOOD STOP TRAILER NICE AND SMOOTH.
all worked out great
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
THE PRODUCT I NEEDED AT A GREAT PRICE WITH A FAST DELIVERY
A+ fast service
it arrived 2 days earlier than expected
