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.

Video Transcript for Hydrastar Brake Actuator - Electric-Hydraulic Brake Actuator - HBA-12 Review

Today we're going to take a look at the HydraStar electric over hydraulic actuator for drum brakes. This has a 1200 psi rating. Now this HydraStar electric over hydraulic actuator will offer a fast response time for shorter stopping distances in emergency situations or even in everyday towing. You can control those fractions of seconds that matter when it comes to stopping your trailer. This actuator has a 1200 psi pressure which is suitable for 8,000-pound and larger drum brake applications. It will work on single, tandem and triple axle trailers with drum brakes. This will eliminate the feel of being pushed by the trailer.

It also eliminates problems found when backing a trailer uphill with surge brakes or even brake drag. It will eliminate the brake drag which is common with surge brakes on a downhill grade. As you can see this actuator is in a nice sealed, extruded, anodized aluminum housing. It is designed to mount to the trailer, connects into your trailer's wiring and the hydraulic brake lights. Now this does require the use of an end 00:01:00 cap brake controller.

It will work with most electronic brake controller that have electric over hydraulic brake function. This does require a breakaway kit. We do sell it separately on our website. It's part number HS496-82. Again, it's listed on this product page as a related product. This connects to the 12-volt DC operation.

It is solid state electronics. When you put brake fluid in here, here's the filler tube, take the cap off. You can use DOT3 or DOT4 brake fluid in here. Now the HydraStar actuators are very easy to install. They do meet all DOT and federal braking requirements unlike some of your surge brakes which are illegal in many states. To install this ...

First I want to go over and show you a few of the things. We showed you the filler cap and where you put your brake fluid in. Right here is a bleeder valve. You use that to take out any air in your hydraulic system when you connect it. Right down here is your output port. That's where your hydraulic lines will connect to the actuator. Then you have your four wires right here. When you install this, these four 12-gauge wires right here, basically the black wire. This will go to a 12-volt constant power from your tow vehicle. The blue wire, this will go to the output from your end cap brake controller. The white will be your ground which connects to the tow vehicle ground and the yellow will connect to the cold side of your breakaway switch, not the battery side. It comes with this owners manual which is a nice set of instructions and even talks about the features of this actuator. The last thing I want to do is give you some dimensions on this to let you know how large it is. The height from the bottom to the very top, the highest point where the cap is, it's going to be right about 7-1/4 inches tall. The length which will measure from edge to edge or the mounting bracket included. If we put a ruler on that edge to edge will be right at 11-3/4 inches. Then the width at the widest point right here is going to be right at 3 inches wide. That should do it for the review of the HydraStar electric over hydraulic actuator for drum brakes with a 1200 psi rating.
