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 factory 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.
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 factory brake controller, 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.
Durable, Marine-Grade Construction
The Hydrastar Marine actuator is ideal for use on boat trailers. Just like other Hydrastar electric-over-hydraulic actuator models, this system is built of extruded anodized aluminum for superior corrosion resistance. The weathertight seals protect internal components from the elements. The Hydrastar Marine actuator also features marine-grade gaskets and stainless steel hardware that won't rust. These extra features make it perfect for marine applications.
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.

It working good on my M105A2 Military trailer. Thanks etrailer.
Substituted the Hydrastar unit for the surge brake actuator on my military surplus trailer. Works like a champ!
I ordered the brake controller yesterday I already have it today so it was here in one day quick service I don’t have time to put it on right now but when I do I hope to let you know how it works thank you . I Purchased a titan brake controller probably five years ago and it on a cattle trailer so I didn’t use it a whole lot and the motor went out on it very quick so I was disappointed in that brand and I thought I’d try this hydrastar system hope I have better luck with it . Thanks
Melisa was very helpful on the phone and promptly shipped my parts. Appreciate it very much.
I installed it in just a few hours, and set it to the most aggressive setting. My wife and I have wanted one for a few years after a few close calls pulling our boat. Well, weirdly enough, this product paid for itself in the first week. A car pulled out right in front of us on a highway. I was able to avoid the crash, that if this product was not on, we would have hit. Pulling a 10 thousand lb boat, one just cannot stop on a dime doing 60 mph. The next week on the way home from the lake, a moose stepped out onto the highway, once again, was able to stop! My wife is happy as we had a few close calls and she was very happy and it was money well spent. Wished we had bought it sooner.
etrailer as always has what I need, ships fast, and product is "as advertised"!
A pleasure to talk to the tech's when I have questions and even go as far as calling manufacturer to verify equipment selections.
Keep up the GREAT work.
Great reliable product. It handles my 12,000 lb. boat and trailer on wet or dry roads.
Had a problem with first shipment , was resolved promptly
a very nice woman took my order ...she said it would ship in x business days ....i said never mind that put down the phone and run and ship my order ..she laughed and said they didn't let her into the warehouse...however if she didn't pack it up herself immediately, someone else did ..i had it way before i expected it ...hydreastar product ..1sr one lasted about ten years of almost 5 days a week use on an equipment trailer ..i expect to get same service from this one ...
Well built unit that works well .
Unit work’s very well and was easy to install .I am looking forward to a wonderful safe trip pulling my 12,000 lb boat 600 miles north to San Juan Islands and British Columbia.
Item arrived earlier than expected. Installation was easy. And now my trailer brakes work again.
Easy install, works great. Installed a whole EOH system with this unit at the core. Excellent.
Shipping box was ripped, should of had more packing material, fortunately everything was still in the box.
GREAT PRODUCT
