Electric-hydraulic brake actuator with brake lines lets you use an electric brake controller from inside your vehicle to adjust and control your trailer's hydraulic brakes. Enjoy convenience as you achieve greater braking control and performance.
Features:
Specs:
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. 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
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 superior corrosion resistance. The weathertight seals protect internal components from the elements.
Brake Controller Compatibility
Not all electric trailer brake controllers 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.

It should not take that long for your electric over hydraulic brakes to react. You will want to bleed your brakes again to make sure that there is no air in the system. Also, if you an OEM brake controller you will need to replace that with a brake controller that is designed to work with electric over hydraulic systems, like the Tekonsha Prodigy P3 Trailer Brake Controller - 1 to 4 Axles - Proportional Part # 90195.

You mentioned that the fittings were showing some signs of rust. The brake lines that we carry that are stainless steel typically will have fittings that are not and therefore can rust. I recommend looking at a brake line kit like part # 20TR-BLKIT which has brass fittings or you can also use a product like Never-Seez to protect the current fittings.

This has been the best upgrade hands down that I could have done, and Im sure when it comes to stopping quickly, there is no better choice than a hydraulic electric disk brake system
