Hydrastar Brake Actuator - HS481-8067

  • Disc Brakes
  • Electric-Hydraulic Brake Actuator
  • Hydrastar
  • 1600 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 brakes. Includes rust-resistant 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 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
  • 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 disc brakes
  • Maximum output pressure: 1,600 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.


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 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.

Yes, of course we can send you out a replacement. I am sorry this happened, let me get you over to customer service.

Outstanding addition to my Reflection 5th wheel. Back from 7000 mile trip to Canada and no problems whatsoever. One panic stop and brakes were very effective. With over 80,000 on my trailer this is this first trip without some kind of brake issue: broken wire, needs adjustment, put together incorrectly at dealers, etc. I installed the unit myself. Relatively straight forward.

I did get confused on the wiring, could have been just me, but a separate wiring diagram for a 5th wheel might help. I didn't realize (and probably should have) that the emergency brake needs to get it's hot from the existing trailer battery and the main braking control has to get it's hot from the truck. All of this can be done in the pin box and is actually pretty straight forward.

Great product. Should have installed years ago.

  • Recommended Disc Brake Conversion Parts For a 2019 Grand Design Reflection 337RLS 5TH Wheel Camper
    For your 2019 Grand Design Reflection 337RLS I recommend the Kodiak Disc Brake Kit # K2HR526D. This uses the same 6 on 5-1/2" bolt pattern for your current wheels and has a Dacromet coating to prevent corrosion. You will need 2 of these kits for both your axles along with 2 of the Bearing Kits # DBRKHW6EZ. I recommend using the Hydrastar Vented Marine Electric Over Hydraulic Actuator # HS481-8067 as it allows for a simpler plug and play installation of the components. Then you will be...

  • What Are The Differences Between The HydraStar # HS381-9067 and HS481-8067?
    The HydraStar Marine Electric Over Hydraulic Actuator w/ Breakaway and 7-Way RV Harness # HS381-9067 is designed to work with an aftermarket electric over hydraulic brake controller. This kit will require you to wire in the components using the wire connectors that are included with the kit. I recommend using this kit if your trailer doesn't already have a 7-way trailer connection as you will get the junction box that allows you to wire up the trailer correctly. The HydraStar Vented Marine...

  • Brake Controller/Break-Away System for Hydrastar Disc Brake Electric/Hydraulic Brake Actuator
    We don't offer an all-inclusive kit that offers everything you listed but I'd be happy to recommend some parts for you that would come pretty close, you'd need to get the brake controller and it's wiring harness separately. For a brake controller, you can't go wrong with a # C24VV Curt TriFlex. You'll also need the # C51451 wiring adapter harness which allows a plug and play installation into the junction box under the dash. This controller is out-of-the-box compatible with electric over...

  • 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...

  • 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...

  • 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...

    We have all of the parts needed to convert an 8k trailer axle to disc brakes but we don't have it as a single part number like we do with some of the other axle capacities. So the best actuator is the Hydrastar as we have found that they are by far the most reliable and quickest reacting. For that you'd want the Hydrastar kit part # HS481-8067 which also comes with the breakaway kit, battery and wiring needed. Then you'll need the brake line kit part # HS496-252.

  • Parts Needed to Convert Boat Trailer w/ 10 Inch Electric Drum Brakes To Hydraulic Disc With Oil Hubs
    First you will want to verify exactly what size axle you have but it is most likely a 3,500LB axle. I recommend using a Digital Caliper # PTW80157 to verify the grease seal and bearing landing sizes on your spindle. A typical 3,500lb axle will use a Grease Seal # 58846 (1.719" ID), Inner Bearing # L68149 (1.378" ID) and Outer Bearing # L44649 (1.063" ID). If this is what you have here is a list of all the parts you will need for the hubs, otherwise please let me know your spindle dimensions...

  • 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...

  • Is BrakeRite SD Control Module Replaceable
    The Replacement Remote Mounted SD Control Module for BrakeRite II T4834200 was discontinued back towards the start of 2021. You might be able to find a lone one being sold at a resale website or shop but my guess is you'll have a hard time finding one and you'll need to replace the whole brake system. If you really like the BrakeRite system then I recommend picking up the Titan BrakeRite I Plug and Play Electric-Hydraulic Actuator Kit # T4813102 which is still compatible with disc brakes,...

  • Recommended Electric Trailer Brakes For 6,000LB Boat Trailer Axle
    You can install electric brakes on a boat trailer but it is not recommended to use the electric brakes when they get submerged in the water. The Electric Trailer Brake Kit # AKEBRK-7-D has a Dacromet coating for superior corrosion resistance due to being submerged in water. If this is the route you choose you will need to ensure your hub is okay to use with electric brakes. Or we have the Galvanized Easy Grease Trailer Hub and Drum Assembly # AKHD-655-6-G-EZ-K.

  • Recommended Replacement Electric Over Hydraulic Actuator For Titan Grizz Actuator
    I find the Hydrastar Vented Marine Electric Over Hydraulic Actuator # HBA16 is a more reliable system than the Dexter BrakeRite Actuator # DX36XR. We have it available as a Plug and Play Kit # HS481-8067 much like the Dexter BrakeRite # T4813102 you found. The Hydrastar Kit # HS481-8067 does include a module which allows you to use it with most factory brake controllers.

  • Is Additional Components Needed with HydraStar Kit When Used with Two Vehicles
    All of the components of the HydraStar Vented Marine Electric Over Hydraulic Actuator for Disc Brakes # HS481-8067 that you referenced install on the trailer side of the towing setup so you wouldn't need anything different from the kit for using it with two different vehicles. You would need a brake controller installed in the vehicles that is compatible with electric over hydraulic brake systems like this like the P3 part # 90195.

    Yes, the Hydrastar Vented Marine Electric Over Hydraulic Actuator for Disc Brakes # HS481-8067 would be the correct kit to use on your boat trailer with surge disc brakes. Depending on what type of channel and coupler you have will decide on the best coupler. Most boat trailers will use a 3" wide coupler so you might find either the 2" Ball # DM15000-52 or 2-5/16" Ball # DM13203-52 to be your best option.

This will allow you to bolt the suspension to the trailer rather than having to have frame hangers welded on. It also uses a rubber spring suspension system which is more progressive than steel and will help reduce bouncing much better. You will be able to attach 2 Straight Axles # 7359765-I or 4" Drop Axles # 7685269-I with idler hubs. I do recommend checking your local laws for trailer...

    If you wanted to drill holes in the Demco Coupler # DM13203-95 to make it easier to attach to your trailer frame you certainly could. Just be mindful where you drill the holes and don't turn it into swiss cheese. When it's time to pick out an electric over hydraulic kit I would highly recommend the Hydrastar actuators as they are the most reliable and among the quickest reacting. For a kit that comes with everything for your trailer you would want the # HS481-8067.
