Features to know about

Strong and Steady Braking for Heavy Loads: 12,500 lbs Capacity

This bolt-on surge actuator is built to handle serious weight, rated for up to 12,500 lbs with a maximum tongue weight of 1,250 lbs. It’s a dependable setup for trailers running hydraulic drum brakes. When your tow vehicle slows down, the actuator automatically applies pressure to the master cylinder for smooth, proportional braking—no electronics needed.

Smooth Motion Every Time: Efficient Roller Design

The unique roller design keeps the actuator telescoping straight and true when braking. It cuts down on internal resistance so movement stays even and consistent. That means better control during stops and less wear on both your trailer and braking components over time.

Tough Enough for Heavy Work: Durable Steel Construction

Made from sturdy, durable steel, this actuator resists bending and twisting even in tight turns or jackknife situations. The primed finish gives you a layer of protection while letting you paint or coat it to match your trailer once installed. It’s the kind of unit built to hold up in farm, construction, or equipment trailer use.

Simple Mounting: Bolt-On for 3" Channel Tongues

Installation is straightforward thanks to the bolt-on design that fits a standard 3" wide channel tongue. There’s no welding or special tools needed, making setup quick and clean. A breakaway kit is included for added safety if the trailer separates from the tow vehicle.

Ready for Real-World Use: Works with Free-Backing Drum Brakes

Since this model doesn’t include a reverse lockout, pairing it with free-backing drum brakes keeps things simple when backing up. You can reverse without your brakes engaging unexpectedly—ideal for maneuvering around job sites or loading areas.

Video Transcript for What to Know About the Dexter Brake Actuator

Hello, etrailer neighbor and friends. Steven here. We're looking at the Dexter brake actuator with a painted finish, and it's made for drum brakes. It's a simple bolt on application and it's rated for 12,500 pounds max. Now folks, this hydraulic actuator synchronizes your trailer brakes with the towed vehicle brakes. It's got a unique roller of design that's built inside that's gonna reduce the resistance during the telescoping in and out to help create a straight line.

So if you're not familiar with these, it's bolted on when you have everything in place. This piece can actually telescope in and out, and when it's coming in, it's pushing brake fluid out the pieces at the back, out the hose lines that are connected when you install it. And it's applying the brakes at the trailer side. It's got the breakaway actuator here with a nice long chain and S hook, and that way you could also have the emergency engagement if needed. It's very sturdy, it's a nice heavy duty, solid steel construction.

It's gonna resist bending, jackknifing, that kind of stuff. And the coupler for this is sold separately, so you will need a coupler if you don't already have one. And again, it has the breakaway kit and chain included. It's a painted prime finish, so it's really a prime paint, but you can paint any color you want. I do recommend making sure you put another coat on this.

I think a lot of people just install these and they don't paint 'em again. The primer's gonna last for a while, but you really do need to coat it again with a color just to give it that extra coverage and durability. As I mentioned, it's a simple Bolton installation. You got all the bolt holes here to match up onto the three inch wide channel tongue. So let me tilt this back, give you a better view.

So this is three inch here. It's gonna fit a three inch wide channel. And again, this works with hydraulic drum brakes, drum only. The capacity again is 12,500 pounds. That's also stack on top here in the middle. The maximum tow weight is 1,250 pounds. A nice one year warranty. This again, folks, is the Dexter brake actuator for drum brakes. I'm Steven, thanks for watching, have a great day.
