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

Hydrastar Installation Diagram

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.

It seems that the manufacturer prefers to handle all warranties. Lets get you their information via email.

Perfect! Exactly what we needed to complete the job.

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!



by:

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.



by:

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.



by: 03/02/2021

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.



by:

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



by:

I’ve been installing these HBA - 10 actuators on new trailers for a year now and they have been working great.



by:

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.



by:

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.



by:

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.



by:

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

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

Patrick B.

What brake controller do you have installed in the vehicle? Not all brake controllers will properly operate an electric over hydraulic actuator pump. Some require a different mode or setting to accomplish such. It also may be good to make sure the system is wired properly. Check out the wiring diagram towards the bottom of the page on the HBA-16 actuator.

  • Carlisle Hydrastar Electric Over Hydraulic Trailer Brake Actuator Does Not Cycle On/Build Pressure
    Your Hydrastar actuator is not cycling on to build pressure to apply the brakes when needed. This could mean that there is an electrical problem or a malfunction with the motor, or even a problem with the brake controller You have stated that there is confirmed 12 volt power going to the unit but it could still be an electrical problem. You can also make sure that the Hydrastar white ground wire is connected to the vehicle ground and not to the trailer. They are very particular about...

  • Can an Electric Over Hydraulic Brake Actuator be Ran Dry Temporarily.
    If an electric over hydraulic actuator is temporarily ran dry it will be just fine. We have spoke with our contacts at Dexter and Hydrastar and they have said that they have ran their actuators dry before and never had a problem with them once they refilled them. You'll want to refill the system and then bleed the brakes as soon as you can.

  • Electric Over Hydraulic Actuator Recommendation for Converting a Surge Brake Trailer
    All that would need to change on your trailer is the actuator. You would need to run the brake line of your trailer to an electric over hydraulic actuator like the part # HBA-10 instead of to your surge brake actuator. This actuator is compatible with drum brakes like what your trailer has. This actuator is also compatible with your factory brake controller in your 2012 Ram 2500. I attached a help article on adding EOH brakes to a trailer that you may find helpful as well.

  • Is it Possible to Tow Military Trailer with Air over Hydraulic Brakes with 2015 Ford F-250
    You would have to convert the trailer over to a different braking system to use the controller in your 2015 Ford F-250. This would require a lot of changes to the trailer including the hubs and drums, brake assemblies, wiring or hydraulic lines added depending on the system, a coupler depending on the system, and other miscellaneous items for installation.

  • Testing the Hydrastar 1600 PSI Electric/Hydraulic Actuator for Proper Function
    I spoke to the manufacturer and he said that assuming the unit is getting a full 12 volts, the best thing to do would be to bench test it. A 12V power source will be needed to do so. Isolate the wires of the Hydrastar (black, blue, white, yellow) 1. Attach black wire to the positive terminal and white wire to negative terminal of the 12v battery. Nothing should happen 2.

  • Troubleshooting Hyrdrastar Electric Over Hydraulic Brake Actuator for Drum Brakes
    The ticking sound is definitely not normal. I contacted HydraStar to see if this is something they've run across and they said to start by checking your ground wires and make sure they're connected directly to the breakaway battery. The next step would be to check the rest of the wiring for any kinks or pinches. If you check the wiring and are still getting the ticking sound let me know and we can perform more troubleshooting.

  • Is 2014 Ram 2500 OEM Brake Control Compatible w/Hydrastar Electric Over Hydraulic Actuator HBA-10
    According to the fine people at Hydrastar the factory brake controller in your 2014 Ram 2500 is compatible with actuator # HBA-10. Check the owner's manual or fiddle around with the controller because at some point Ram started including an actual electric over hydraulic mode with the factory controller. If yours has that feature then make sure that it is in that mode.

  • Electric Over Hydraulic Trailer Brake Actuator for Disc Brakes with a Maximum 1,000 PSI
    The only difference between a disc brake actuator and a drum brake actuator is the psi. Generally disc brakes require about 1,500 to 1,600 psi. Since your disc brakes have a maximum psi of 1,000 psi your solution is to use a drum brake actuator. I recommend the HydraStar, part # HBA-10. Since the actuators are identical otherwise this will work just fine for you.
