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.
Pair the HydraStar electric-over-hydraulic actuator with your trailer's disc brakes to get the best possible braking setup. With disc brakes, you already have more consistent braking at higher speeds and a shorter stopping distance than you'd get with drum brakes. In addition to more reliable braking, you also have less cost to maintain the brakes as there are fewer moving parts. Combine these benefits with an electric brake controller and you'll get greater control over your already superior brakes, providing you with the best braking performance.
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 disc brakes. Vented end plate releases heat. Hydraulic lines and breakaway sold separately.Great product, I in stalled it my self it was pretty easy i also bought new rotors calibers and break lines. I bleed the lines then tested the whole system. and WOW! THE STOPPING POWER That i have now is awesome electric over Hydraulic is amazing. I would definitely recommend E-trailer for all your needs. P.S. I don't usually leave a review but this worth mentioning 707734
Product was delivered within two days after I ordered it. As far as i can tell everything ordered was delivered and should work as expected once installed. 633458

Replaced an original Hydrastar with a new one. Works great on my 28 ft triaxle boat trailer with disk brakes. 820223
Everything I have purchased from you had been the highest of quality. Very quick delivery. I rebuilt my boat trailer with your part and I couldn't be happier 811433
Product arrived promptly and looks like installation will be straight forward. Excellent quality unit. 776438
I changed out my electric drum brakes on my Montana fifth wheel with this hydraulic brake actuator and Kodiak discs rotor system . What a difference this new brake system has made. I can now lock down the trailer tires if needed and drive much more relaxed on the highway knowing I can stop on a dime. 764336
This actuator along with the Kodiak disc brake kit has improved the stopping function and shortened the distance substantially. 763984
I have taken a trip from Mich to the black hills and back. Put around 3000 mi. On the fifth wheel since I converted it to hydraulic brakes. The hydrastar actuator worked great as well as th he kodiak brakes. I wish I would have converted it long before now. Hydrastar and Kodiak is the only way to go 763729
Installed the electric over hydraulic unit as well as the HBA-CAM. Couldn't be happier 745166
I upgraded the 32" 12,000 lbs rated trailer to Electric/Hydraulic as the electric brakes really were not doing very much to help slow the trailer down. The overall upgrade included new 7,000# axles as well as this hydraulic converter next to the winch in the front of the trailer. If I ever get another trailer, this unit will be spec'd into it 711788
Have been using this brake actuator for a year now with absolutely no issues. Other people who have committed on how much better my trailer brakes better than theirs. I’m looking at ordering another one to be placed on a trailer I’m changing the axles out on. I’m going from electric brakes to the hydraulic brakes. Great product 711724
Kodiak disk brakes on a 95 EBY stock trailer. Made a real trailer out of it... JK... 710616
It was a replacement for a failed unit, the person on the phone was pleasant and knowledgeable. 697592
Fast Shipping. Great service.... Will buy again... 666600
This is the preeminent hydraulic disc brake pump. It is built like a tank. I couldn’t be more happy with not only the stopping power, but the response time. I highly recommend hydrastar. Also, the packaging was impressive as well. This is a product designed to ride on a bumpy trailer in all the elements nature can throw at it. Yet etrailer still took the time to package it as if it were some fragile glassware. That’s impressive. 664443
Great product, came in just like I was told, easily mounted where my other was,works great 656097
William - 06/12/2020Got it in great time new people are great to do and it will be a while week or two before installing thank you that’s what I ordered 655278
Install was a breeze! The wiring of this unit was different than my two wire actuator that come on my generator trailer, but, the directions were easy to follow and it works like a charm! 651676
The break bleeder value was over tightened from the factory. Using a line wrench, it rounded off the value. Had to use a vice grip to unscrew it. Called the manufacture they had a replacement value to me in two days. Works great and great customer service from the manufacture. Not so much from etrailer. 647017
The unit failed after about one month. I called etrailer and they gave me the info to file a warranty claim with the manufacturer. The manufacturer had a replacement to me in a day and a half with a shipping label for the bad one. The replacement has been solid for 11 months with 60,000 miles on it. This was a great upgrade! It’s worth the money. Braking is so much better. I use this on a 33 foot 16,000 flatbed for work. I can stop with confidence every time now. 640814
I just received eoh trailer brake actuator. I will be installing it soon on my triaxle boat trailer, packaging is in good condition, so the actuator should work as intended. Service is outstanding as usual, shipping was excellent. If the Canadian dollar was i stronger i would certainly make more purchases from E-trailer. Thank you 639834
Michael - 05/09/2020Great customer service and great shipping time. Selection and price is outstanding 639743
product showed up on time in working order, but was aesthetically damaged, the mounting tabs were bent and scratched ,it wasn't during shipping because the box was undamaged , so i would return it as its going on a 75k $ dollar polo trailer but my customer needs it asap the free shipping was nice , but would have gladly paid more for an undamaged actuator. 633848
David - 04/22/2020Ordered easy, arrived fast. not installed yet. 629548
Trailer Brake actuator is working flawlessly. Perfect size and I love the slimline dimensions. 625595
