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

Anodized aluminum electric-hydraulic actuator with control adapter module (CAM) lets you use your Ford, Chevy, or GM factory brake controller to activate your trailer's hydraulic drum brakes. Includes marine-grade gasket and hardware.


Features:

  • Electric-over-hydraulic brake actuator activates your trailer's hydraulic brakes when you apply the brakes in your tow vehicle
    • Factory brake controller sends signal from tow vehicle to actuator when you apply the brakes in your tow vehicle
    • 7-Way trailer connector (sold separately) is needed to transmit signal from brake controller
  • Control adapter module (CAM) included for compatibility with your Ford, Dodge, or GM factory brake controller
    • Easy plug and play install - no hardwiring required
  • 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 superior corrosion resistance
    • Marine-grade gasket and stainless steel hardware make this ideal for marine use
  • 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-, tandem-, or triple-axle trailers 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 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.

  • Is A Hydrastar Electric Over Hydraulic Actuator Adapter Module Needed For A 2020 GMC Sierra 1500
    We have found that trucks that integrated trailer brake controllers can be very temperamental when used with electric over hydraulic brakes. With that being said I recommend the Hydrastar Vented Marine Electric Over Hydraulic Actuator for Drum Brakes # HS481-8065 that has the CAM already included. The CAM will prevent an issue from the start or developing over time because vehicles can now receive over the air updates that cold cause issues. The 7-way plug that is included will contain...

  • Can Electric Brakes Be Installed and Used on a Boat Trailer While It Is Submerged in Water?
    I do have a recommendation for you as electric brake assemblies should never be connected when submerged in water. Instead the best route to go would be to use an electric over hydraulic actuator such as the Hydrastar Drum # HS481-8065 or Disc # HS481-8067. These kits are specific to either drum or disc brakes and include weather tight connectors to keep out moisture. You will be able to pair these with your current hydraulic brakes, or if you can provide me with details on your current...

  • Is a Hydrastar Electric Over Hydraulic Actuator Adapter Module Needed on a 2021 GMC Sierra 3500HD
    What we have found is the integrated trailer brake controllers on trucks can be very temperamental when used with electric over hydraulic brakes. I do recommend using a HydraStar Electric Over Hydraulic Actuator Adapter Module # HBA-CAM with your factory brake controller on your 2021 GMC Sierra 3500HD. This will prevent an issue from the start or developing over time since vehicles can now receive over the air updates that could cause an issue. If you are installing the electric over...

  • Switching a 2002 Tricker Boat Trailer From Hydraulic To Electric Brakes
    Replacing the coupler on your tongue is going to less complicated than you may think. Based on images I could find for your 2002 Tricker Trailer it appears the coupler surge coupler simply bolts in place. If you measure the bolt hole spread and width of your tongue I will be able to verify a coupler like the Demco # DM13203-95 can be used. As far as switching to electric brakes you can switch out the brakes and run wiring or use a kit like the Drum # HS481-8065 or Disc # HS481-8067 brake...

  • Electric-Over-Hydraulic Actuator and Breakaway Battery Kit Recommendations for 3,500 lb Trailer
    Happy 4th to you as well, Jerry! Since you already have your 2017 Toyota Tundra set up for electric brakes you just need to add an electric-over-hydraulic (EOH) actuator and the breakaway battery kit. Here is what I recommend for your application: - Actuator for Drum Brakes # HS381-8066 - Actuator for Disc Brakes # HS381-8067 - Breakaway Battery Kit # 20400 Attached are some review and installation videos for you to check out!

  • Recommended Electric Over Hydraulic Actuator For a Tandem 3,500lb Axle Boat Trailer
    I recommend using either of our Hydrastar Vented Marine Electric Over Hydraulic Actuators. We have a kit for Drum # HS481-8065 or Disc # HS481-8067 brakes. Both of these kits use plug and play connectors for the breakaway battery, trailer disconnect, and brake controller module. As your trailer likely only has a 4-way you can use the Adapter # HM47365 to make the trailer connector plug and play. If you can provide me information on your surge coupler I can help you find a replacement...

  • Can You Switch The Brakes On a U-Haul Trailer Over To Electric?
    Yes, it is possible to convert your U-Haul Trailer from hydraulic to electric trailer brakes. Using a kit like the Hydrastar Vented Marine Electric Over Hydraulic Actuator for Drum Brakes # HS481-8065 allows you to keep your brakes and brake lines already on your trailer. It will only then require a Coupler # DM15000-52 to replace your surge coupler. If you can send me an image of your coupler and tongue dimensions I can use that to help verify the easiest coupler you can use to replace...

  • Are Electric Over Hydraulic Brakes Required To Have Trailer Brakes Work at Boat Ramp?
    You will need to use electric over hydraulic brakes to back down a boat ramp and still have the brakes apply. A Surge Actuator # DM72VR will not apply the brakes since the weight of the trailer is pulling the trailer back down the hill versus pushing into the tow vehicle. I do not recommend using electric only brakes since the electromagnet for the brakes will be submerged in water when launching or retrieving your boat. You will want to add either the Hydrastar kit for Drum # HS481-8065...

  • Options For Converting Trailer With Hydraulic Surge Brakes To Being Controlled By a Brake Controller
    I have a couple options for your 1996 Jayco camper. The easiest option will be to add either the Hydrastar Vented Marine Electric Over Hydraulic Actuator for Disc Brakes # HS481-8067 or for Drum Brakes # HS481-8065. This will allow you to retain all your hydraulic lines, brakes and drums on your trailer. Both kits include a breakaway battery, breakaway switch and the hydraulic actuator and wiring needed to install them. You will need an Adapter # PK12716 to plug your 4-way flat into the...

  • Best Parts Needed to Convert Komfort Fifth Wheel Trailer to Disc Brakes
    The Kodiak Disc Brake Kit part # K2HR89DE would work well for your Dexter 6k axles. This fits the spindles your trailer has, is 8 lug, has 9/16 inch diameter wheel studs and also has an e-coating to fight corrosion. Then for an actuator kit that includes the best actuator, the needed brake lines, and a breakaway kit you'd want the Hydrastar part # HBA16-252-82 and you'd have everything else you'd need to convert your Komfort fifth wheel to disc brakes.
