Hydrastar Vented Marine Electric Over Hydraulic Actuator for Drum Brakes - OEM - 1,000 psi

Hydrastar Brake Actuator - HS481-8065

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

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.
