Hydrastar Brake Actuator - HBA-10

  • Electric-Hydraulic Brake Actuator
  • Drum Brakes
  • Hydrastar
  • 1000 psi

Anodized aluminum electric-hydraulic actuator lets you use your brake controller (sold separately) to activate your trailer's hydraulic drum brakes. Vented end plate releases heat. Includes hardware. Hydraulic lines and breakaway sold separately.


Features:

  • Electric-over-hydraulic brake actuator activates your trailer's hydraulic brakes when you apply the brakes in your tow vehicle
    • Brake controller (sold separately) is required to send signal from tow vehicle to actuator when brakes are applied
    • 7-Way trailer connector (sold separately) is needed to transmit signal from brake controller
  • Improved functionality when compared with surge brake couplers
    • Faster response time - trailer brakes are triggered when you apply brakes in tow vehicle, as opposed to when trailer pushes against hitch ball
    • No need to manually lock out brakes when you back up
    • Trailer brakes can be intentionally activated when you reverse
    • Manual override on brake controller can be activated so you can engage the trailer brakes without having to apply your vehicle brakes
  • Vented end plate releases pressure, moisture, and heat in order to protect the internal components
    • Allows actuator to be mounted in places where most actuators would overheat
  • Electronic, proportional pressure valve ensures that braking is smooth and effective
  • Built-in bleeder screw lets you easily flush air out of the brake lines
  • Durable extruded aluminum provides corrosion resistance
  • Compatible with any standard, 5-amp-hour-battery breakaway kit (sold separately)
  • DOT compliant
  • Unit installs on trailer frame and connects to trailer's wiring and hydraulic brake lines (sold separately)
  • Made in the USA


Specs:

  • Application: single- and tandem-axle trailers (up to 7,000 lbs) with drum brakes
  • Maximum output pressure: 1,000 psi
  • Power: 12V DC
  • Hydraulic port size: 3/16"
  • Dimensions: 11-3/4" long x 3" wide x 7-3/8" tall
  • Wire configuration:
    • Black: 12-volt power
    • Blue: brake controller
    • Yellow: breakaway
    • White: ground
  • 2-Year limited warranty


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.

Comments
Have Hydrastar HBA12 1200psiG7 on tandem boat trailer. Breakaway activates brakes well but brakes activated thru vehicle do not work.A check of power from vehicle to trailer indicates circuits are all good. Can hear contact noise from inside brake unit but pump doesnt start but thru breakaway activation the pump works well.Have been told the fault is in the Electronic Chip that activates the pump. Is this correct and if so can I purchase that part only? What part number do I order? Appreciate your reply. John B

What brake controller do you have installed in the vehicle? Not all brake controllers will properly operate an electric over hydraulic actuator pump. Some require a different mode or setting to accomplish such. It also may be good to make sure the system is wired properly. Check out the wiring diagram towards the bottom of the page on the HBA-16 actuator.

Very good product, it works well with my trailer. Much better than electric drum brakes. Only down fall is I found it is sensitive to voltage spikes. I had a faulty alternator and the control board in the unit burnt out. Somewhat disappointed that replacement parts were not available to repair my current unit. Had to replace that whole unit just for a small circuit board. Great unit otherwise as far as function. 668739

I have a tandem axle dump trailer that came with factory hydraulic surge brakes. They worked sporatically at best, were very unpredictable, and eventually stopped working all together. I installed the hba 10 as well as an electric breakaway switch and eliminated the surge hitch all together. Works great. Far beyond my expectations. 476094

  • Could Trailer with Electric Over Hydraulic Brakes Have Trailer with Electric Brakes Connected
    So your electric over hydraulic brake actuator is receiving a standard brake controller output signal to tell it how to operate your EOH trailer brakes. So it would be possible that you could take this circuit (most likely blue wire) and extend it from where it connects to the actuator to the back of the first trailer so that you could then connect it to the electric brakes of your second trailer. You'd need 10 gauge wire like part # 10-1-1 (sold by foot) to get the circuit to the trailer...

    You should just need an electric over hydraulic actuator such as # HBA-10 for drum brakes or # HBA16 for disc brakes. You should not need any additional brake lines or anything because the actuators work with the hydraulic lines and brakes that are already on the trailer.
