Features to know about

Strong Braking for Heavy Loads: 12,500 lbs Capacity

This actuator is built to handle serious weight with its 12,500-lb gross trailer weight rating and 1,250-lb maximum tongue weight. It’s made from sturdy steel that resists bending, even in tight jackknife situations. Whether you’re towing equipment, a boat, or a utility load, the heavy-duty coupler and surge-type design apply smooth braking through your hydraulic drum brakes.

Smooth Operation on Every Stop: Efficient Roller Design

The unique roller setup inside the actuator cuts down resistance when it telescopes, which keeps the movement straight and predictable. That smooth action helps synchronize your trailer’s braking with your tow vehicle’s deceleration so you get stable, even stops every time.

Ready for Real Work: Durable and Easy to Mount

This unit bolts right over a 3"-wide trailer tongue with a simple bolt-on setup—no complicated fitting or welding required. The primed finish is ready for paint, making it easy to match your trailer and add an extra layer of protection before it hits the road.

Extra Safety Built In: Included Breakaway Kit

If your trailer ever separates from the tow vehicle, the included breakaway kit automatically activates your trailer brakes to help bring everything to a stop. It’s one less thing to worry about when you’re hauling heavy loads or working on uneven ground.

Consistent Control: Surge-Type Design for Drum Brakes

With its surge-type hydraulic system, the actuator automatically responds to your vehicle’s braking force. When the tow vehicle slows down, the actuator telescopes forward to push hydraulic pressure through to your drum brakes. It’s a simple, mechanical setup that delivers reliable stopping power without needing any electrical hookup.

Video Transcript for A Closer Look at the Dexter Brake Actuator

Today, we'll be taking a look at the Titan Brake Actuator. This is gonna act as a mechanical sort of brake controller for our trailer basically as we come to a stop in our towing vehicle. Our trailer's gonna wanna keep moving forward and that's gonna push against the actuator, which will activate it and then push hydraulic fluid to our brakes bringing our trailer to a stop. So, it's kind of a push pull system, makes for a mechanical brake controller. This works with our hydraulic drum brakes so we'll see at the back we'll have our connection point there for the hydraulic line. At the top, we'll have a cap for our reservoir.

We pop that off. I have to use a screwdriver, you might not have to. I just have kind of weak fingers. And then at the top, we'll have our cap for that reservoir and it does have a little label on there printed to use DOT type three fluid. So, handy little reminder on what it needs to use.Can unthread that and fill that reservoir there with our fluid as needed.

You'll also notice that we'll have this chain that's gonna be our breakaway switch so in the event that our trailer comes accidentally disconnected from our towing vehicle, it's going to activate that level at the top and bring our trailer to a stop. So, it'll pull that lever and that'll activate our breaks to bring our trailer to a stop. You'll just run this chain up to your towing vehicle. It's got a little S hook on the end so you wanna attach that to your safety chain loops on your hitch. Now it's a primed finish so that'll help to keep down rust and corrosion but since it's just primed you will want to paint this over again to make sure that it's completely rust resistant.We'll also have a greaser up here at the top so you can do a little maintenance here, make sure everything's lubricated and working properly.

Has a roller design to help reduce any resistance whenever that actuator's telescoping out to create that nice straight line movement. The construction is a durable steel so that's gonna help to resist any kind of bending in those jack knife situations where we're coming to a stop and turning at the same time or anything like that. Has the standard heavy duty coupler. This is going to work for ball sizes two and five-sixteenth inch. Has a three inch wide mounting channel.

This is intended for a bolt on application. Three inch wide channel down there at the bottom. We'll have a couple pre-drilled holes to help get that installed. The two narrowest ones are about three inches apart center to center and those two ones that are a little bit lower and wider are about five inches apart center to center.This has a max capacity of 12,500 pounds at a maximum tongue weight of 1250 pounds. It does come with a one year warranty from Titan and that's gonna do it for our look at the Titan Brake Actuator.
