The aluminum master cylinder holds up better against corrosion than cast steel, which makes a big difference over time. It won’t pit or rust in harsh conditions, so the braking system stays smooth and responsive. That means less worry about internal buildup and a longer-lasting actuator for your trailer.
The low-profile coupler uses an over-center latch that only engages when it’s fully seated on a 2" hitch ball. This design keeps the connection tight and dependable while making it easy to hook up and unhook. You get a solid fit every time without fighting with the latch or guessing if it’s locked in place.
For extra peace of mind, this actuator includes a breakaway cable to provide a secondary connection between the trailer and tow vehicle. It’s an easy, built-in safety add-on that helps reduce the risk of a complete separation if something goes wrong at the coupler.
Built for a 3" x 5" straight tongue, this actuator welds directly to the trailer frame for a solid, permanent installation. The weld-on setup provides strength you can rely on when towing up to 7,500 lbs. Once it’s mounted and primed, it’s ready for paint so you can match it to your trailer without extra prep work.
When you slow down, the surge system automatically activates your trailer’s hydraulic drum brakes. As the trailer moves forward under deceleration, the actuator telescopes to apply pressure through the master cylinder. The result is smooth, proportional braking that feels natural behind your tow vehicle—no electronics needed.
The primed exterior gives you a clean base to finish the way you want, whether that’s matching your trailer color or adding extra protection. Its straightforward design makes maintenance simple, and since there’s no built-in lockout, pairing it with free-backing brakes keeps reversing hassle-free.

Hi everybody. Andy here with etrailer. Let's take a quick look at this Dexter A 60 brake actuator. Now this is a surge brake actuator that's designed for trailers with hydraulic drum brakes. And this is rated for trailers up to 7,500 pounds gross trailer weight. So this is gonna be a solid choice for heavier setups where a dependable braking system really does matter.
Now what makes this nice is that it's fully automatic. It uses a surge braking design, which means that when you slow your tow vehicle down, the trailer's gonna naturally push forward slightly, and that motion's gonna activate the trailer's brakes. So what that means for you is no complicated wiring or brake controllers needed in your cab. This is just going to work in sync with your vehicle. Now, hookup is gonna be pretty straightforward and secure.
This has an over the center latch that's going to lock down when it's fully seated on your two-inch hitch ball. So you're not gonna have to worry about looking. You're not gonna have to worry about this looking to latch, but not actually being secure. So let me give you a brief demonstration of how you hook this up. You've got a tethered safety pin here that you're gonna pull out, and then you just slide this little tab over, and then that's gonna allow you to bring that latch up.
And then that's just going to go over your two inch ball, and then you're just going to close that latch. And then it is important to replace this pin as well because once you have that pin in place, if for whatever reason this latch pops up accidentally, that pin is going to prevent this from coming up all the way. So you're still gonna stay securely connected to your ball. So again, make sure that pin is in place. And then when you're ready to disconnect, you'll just pull that pin out and then open up that latch, and then that's going to allow you to disconnect just like that.
So this is going to give you the extra confidence that you're properly connected before you hit the road. Now, this is built to weld onto a three-inch by five-inch straight trailer tongue. So, this is meant for sturdier trailer frames. Internally, it does use an aluminum master cylinder, and the body here is primed. So this is going to help resist rust and corrosion over time. When you get this welded into place, it's a good idea to paint over this prime finish whatever color you want that's gonna match your trailer to give you that extra added protection. That aluminum master cylinder is gonna be great, especially helpful if your trailer sees regular outdoor storage or wet conditions. Now, you probably already noticed, but this does have a breakaway cable with this included hook. So this will hook to your tow vehicle and prevent a trailer runaway situation. So if your trailer, for whatever reason, unhooks from your tow vehicle, it's going to pull this cable, which will activate the master cylinder to apply the brakes to keep it from a runaway situation. Before I leave you, let me go ahead and put a tape measure up to this. Just give you a rough overall measurement so you have a good idea of the size. So as I hope you can see, we're sitting pretty close to 22 3/4 inches. But if you happen to have any other questions, don't hesitate to reach out to us. We do wanna make sure that you're getting exactly what you need. Well, again, my name is Andy. Thank you for joining me.

Was exactly what I was expecting, good quality, a fair price, and will fit right on my trailer tongue.
Good job!!!
Fast courteous service, great equipment.
I ordered late Tuesday evening. It shipped on Wednesday, arrived Friday and my boat trailer was fixed by Friday evening. Product was exactly as advertised and the perfect replacement for my damaged one. Quick and accurate shipping had me back out fishing by the weekend. Very impressed with etrailer service levels.
worked great
Paul is awesome!!
I was very pleased with the way he handled the order. I was going to order it online but he suggested that he could possibly have it delivered in 3-4 days. Actually it was delivered in 24 hours.
I thought [other retailers] were quick about deliveries till I ordered from etrailer.
The coupler and the brake actuator fit perfectly and definitely was a great replacement from the Atwood coupler.
Thanks. Paul.
Worked great, replaced an old Atwood, welded in where the old one was cut out. Minor modification to the brake line, easy to bleed master cylinder and then bleed brake system. Coupler is extremely easy to use.
I installed this brake actuator on a 3500 lb boat trailer with drum brakes, is working great so far. Needed to replace the existing broken hitch on my trailer and this was a suitable replacement to get the brakes working again.
Product as described and will be the needed replacement for the existing actuator on the trailer.
Perfect fit exactly the part that I nee ded
Installed and working as expected.
Worked well, easy to swap my old one
As advertised and arrived promptly
Great service and fast shipping
My 1993 Jayco 1206 pop-up was originally equipped with an Atwood weld on hitch with surge brake actuator. The actuator became seized and unserviceable and was obsolete, so it couldn't be replaced. I got this replacement hitch, cut the old one off, and had this one welded on. This is a great option and will be much more serviceable in the future. I am very pleased!
Worked perfectly
