  • Bolt-On
  • Electric Lockout
  • Titan
  • Straight Tongue Coupler

Bolt-on surge brake actuator with adjustable drop channel lets you mount a coupler (sold separately) in 1 of 5 positions to fit your application. Electric lockout lets you back up without activating trailer brakes. Roller design reduces resistance.


Features:

  • Hydraulic actuator activates trailer's brakes when tow vehicle slows or stops
  • Electric reverse lockout lets you back up without actuating trailer brakes
    • Built-in shield protects solenoid valve from the elements
  • Offset adjustable channel has 5 different mounting positions for coupler (sold separately)
    • Built-in drop is great for tall trailers
  • Unique roller design reduces resistance during telescoping to create straight-line movement
  • Sturdy, durable steel construction resists bending in jackknife situations
  • Breakaway kit included
  • Corrosion-resistant zinc-plated finish
  • Bolt-on installation


Specs:

  • Application: trailers with hydraulic drum brakes
  • Gross towing weight: 12,500 lbs
  • Maximum tongue weight: 1,250 lbs
  • Mounting: straight, 3" wide trailer tongue
  • 1-Year warranty


When you apply the brakes in your tow vehicle, deceleration occurs and momentum pushes your trailer toward the rear of your vehicle. With surge brake systems, the actuator is triggered as your trailer moves forward, once your tow vehicle starts to slow down. When this happens, the actuator contracts, applying force to its master cylinder. This in turn supplies the necessary hydraulic pressure to engage the trailer's brakes.


Electric Reverse Lockout

The electric reverse lockout on this trailer brake actuator is automatically activated when you shift your tow vehicle into reverse. The solenoid wires into your trailer connector - which connects to your tow vehicle - so that it can detect when you are in reverse. When your vehicle is in reverse, the solenoid ensures that the hydraulic actuator does not activate your trailer's brakes, thus allowing you to back up your rig. To use the lockout feature, you must have a 5-pole flat, 6-way round, or 7-pole trailer connector.


Adjustable Channel Design

The adjustable channel on this trailer brake actuator allows for ultimate versatility. Mount almost any type of coupler (sold separately) - from a standard ball coupler to a lunette ring or clevis attachment - to fit your specific application. In addition, the 3 mounting positions on the channel let you adjust the height of the coupler. Just place the coupler so that it matches the height of the ball mount or other hitch attachment on your tow vehicle and you will be able to tow your trailer levelly.


This actuator is great for tall trailers. This is because the adjustable channel is positioned so that the mounted coupler can sit below the actuator tube, allowing for a greater drop than with a standard center-mounted channel. As a result, you can line up your tall trailer with your tow vehicle's hitch for a level setup.

  • Identifying Free Backing Trailer Brake Assemblies When Replacing Atwood 85778 Surge Brake
    To check for a Free Backing Hydraulic Trailer Brake # AKFBBRK-35 you will need to remove your brake drum assembly. The free backing brakes have a different front brake shoe. This shoe is designed to fall away when the trailer is moving in reverse. The fall away brake shoe will have a pivot point in the shoe that allows it to fall away(See Image). The Demco Hydraulic Trailer Brake Actuator # DM72VR can be used with the free backing brakes as the Demco 8605001 is no longer an active item....

  • Hydraulic Drum Brake Actuator With Electric Lockout
    There are only a few hydraulic drum brake actuators that come with electric lockouts, and the right one will depend on the size of the channel you are bolting it to. The Titan Hydraulic Brake Actuator w/ Drop and Electric Lockout # T4854020 is large, fitting on a 4" wide channel and coupling to a 2-5/16" hitch ball. Based on your trailer's GVWR of just under 6,000 lbs you likely have a 3" wide channel (though you will need to verify this). So what I recommend instead is the Titan Brake...
