With a huge reservoir that holds a full quart of fluid, this actuator is perfect your big, multi-axle camper. Just wire it into your trailer and use your existing brake controller to activate your disc brakes. Lines sold separately.

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.

Hi everybody. Andy here with etrailer.com. Let's take a look at this Hydrostar electric over hydraulic actuator for your disc brakes. Now this is going to work with your single tandem and triple axle trailers with drum brakes and this is going to install on your trailer frame and connect to your trailer's wiring and hydraulic brake lines. And of course those are sold separately. This Hydrostar electrical over hydraulic trailer brake actuator applies pressure to your trailer's hydraulic brake system in response to the electrical signals sent from your end cap brake controller, and 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 has a maximum output pressure of 1,600 PSI. As you probably know, a seven-way trailer connector is needed to transmit the signal from your brake controller and of course that connector is sold separately. This actuator has improved functionality when compared with surge brake couplers. This is going to give you a faster response time. Trailer brakes are triggered when you apply the brakes in a tow vehicle as opposed to when the trailer pushes against the hitch ball.
So there will be no need to manually lock out the brakes when you back up. The trailer brakes can be intentionally activated when you reverse and the manual override on your brake controller can be activated, as I mentioned, so you can engage the trailer brakes without having to apply your vehicle's brakes. The electronic proportional pressure valve is going to ensure that braking is smooth and effective. As you've noticed, this does feature a huge reservoir, which is going to be great for trailers with long brake lines that need high volumes of brake fluid. This translucent tank is going to let you check the fluid levels at a glance and the fluid capacity is 32 ounces.
DOT three or four brake fluid is required and the brake fluid is not included with this. A built-in bleeder screw is going to let you easily flush air out of the brake lines. The hydraulic port size is three sixteens of an inch rather, again, three sixteens of an inch. And this is going to be compatible with any standard five amp hour battery breakaway kit. And that breakaway kit is sold separately.
And in case you're not familiar with the colors here on these wires, their functionality. Lemme just go through 'em real quick. Lemme put this into frame so you can see. So the black wire is going to be for your 12 volt power, and then the blue wire here is going to be for your brake controller. The yellow wire is going to be for breakaway, and then the white wire is going to be for ground. This is made here in the USA of extruded aluminum, so this is gonna be very durable. It's going to be corrosion resistant. And then let me go over some measurements with you. Let me begin by looking at the length first. So I'm just gonna go ahead and tilt this and measure this here at the longest points. So looking at the overall length, we are sitting right about 11 and three quarters inches long. And then here at the widest point we're sitting right at three inches wide. And then the overall height, we are pretty close to almost 11 inches, but if you wanna get technical about it, I'm gonna say 10 and seven eighths inches tall. Now this Hydrostar electric over hydraulic brake actuator will give you years of trailer stopping performance, but you do wanna make sure that you do not power wash the actuator or take it through a commercial car wash. High pressure water may damage the seals on this actuator, just so you're aware of that. Well, I think that's gonna wrap up our brief look today. I do hope that our time together was helpful for you. Again, my name is Andy. Thank you for joining me.
