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.

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.

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.

I need to know how I can connect this 4 color wires on hydrastar actuator to my kaufman trailer??

Etrailer Expert

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.

  • Best Solution for Replacing Atwood Surge Actuator for Drum Brakes
    The Atwood actuators were pretty unique and since they (and the replacement parts) were discontinued only solution is replacing the whole thing. Going to electric over hydraulic would be the best option. For that the actuator I recommend is the Hydrastar part # HBA-12. This is the most reliable actuator we offer and it also reacts the quickest. You most likely will need to upgrade the 4 or 5-way on your trailer to a 7-way which we have a kit designed specifically for that as part #...

  • Compatibility of Tekonsha 90195 P3 Brake Controller With Electric/Hydraulic Trailer Braking Systems
    The Tekonsha P3, you mentioned, part # 90195 is compatible right out of the box with electric over hydraulic brake actuators like the Hydrastar # HBA-12 you referred to. You will need the # 3035-P brake controller wiring harness to install the controller. The harness would plug into the existing connector located under the dash as shown in the linked video. The procedure for setting the controller is mentioned on page 4 of the owner's manual, which I've linked for you.

  • Correct Adapter to Use with HydraStar EoH Actuator for 2015 Chevy Silverado 1500
    Assuming your 2015 Chevy Silverado 1500 is equipped with the factory integrated brake controller, you will indeed need to use the HydraStar Adapter # HBA-CAM with the HydraStar Electric Over Hydraulic Actuator like # HBA-12 for proper operation. These adapters are specific to the actuator so the Titan model will not be compatible.

  • Are Electric Over Hydraulic Trailer Brake Actuators Compatible with Factory Brake Controllers
    It all depends on which electric over hydraulic actuator you are using. If your truck has an integrated brake controller it might be compatible. But you mentioned having a 2009 2500HD but I do not know if it is a Silverado, Sierra, or Ram. If we are talking factory integrated controllers then GM trucks are not compatible with the HydraStar # HBA16, # HBA-12, or # HBA-10 unless you use adapter # HBA-CAM (which only works with the model HydraStars indicated on its product page). It is...

  • Parts Needed To Transfer A Boat Trailer With Surge Brakes To Electric Over Hydraulic
    Since you already have a hydraulic surge brake system on your trailer it's going to be fairly easy to swap over to an electric over hydraulic system. Starting with the trailer coupler, you'll want to lockout the actuator, if possible, or replace it with a standard trailer coupler. If you need to swap out the coupler I'd just need to know the size of the channel the current one is mounted on and the GVWR of the trailer to determine the correct capacity coupler.

  • Can Motor Be Replaced for Hydrastar Electric Over Hydraulic Actuator
    If the motor on your Hydrastar Electric Over Hydraulic Actuator went out then you'll need to replace the entire actuator as the motor is not a replaceable part according to my contact at Hydrastar. You'll just want to choose the actuator with matching specs to what you currently have: Standard: 1,000 psi - # HBA-10 1,200 psi - # HBA-12 1,600 psi - # HBA16 Vented: 1,000 psi - # HS381-8065 1,200 psi - # HS381-8066 1,600 psi - # HS381-8067 Attached are a few review videos for you to check out.

  • Integrated Brake Controller, Hydraulic Brakes and Trailer Wiring for Boat Trailer
    If your boat trailer has a mechanical surge actuator coupler like # DM72VR then no trailer brake controller is required. The inertia of the trailer moving forward provides the compression to push hydraulic fluid to the brakes. If on the other hand you have an EOH system, electric-over-hydraulic, such as with an actuator like # HBA-12 for drum brakes or # HBA16 for disc brakes, then you DO still need a trailer brake controller to deliver the electrical signals to the actuator, which then...

  • Do Hydrastar Electric Over Hydraulic Actuators Run All the Time When Brakes Are Applied
    What you are describing is normal behavior from your Carlisle Hydrastar brake actuator # HBA-12. It's going to run when you have the brakes applied. Without trying to be super confusing basically if the brakes are applied the actuator has to be running to create pressure. It doesn't have a way to create pressure and then hold that pressure without the pump runnig. Also this helps too as if the braking pressure were to suddenly change it would need to be dynamic enough to quickly change.
