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 hydraulic 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 your trailer's brakes.


EZ-Latch Coupler

Cast Coupler Cutaway

This coupler features a simple-to-use latching mechanism known as the EZ-Latch. With this mechanism, hooking up is as easy as dropping the coupler over your trailer hitch ball. The latch does not need to be tugged or manually activated to allow the ball into the coupler socket, nor does it have to be secured in place. Just make sure that the coupler is properly lined up with the ball when you lower it, and the rest is automatic. Disengaging the coupler is just as effortless. Simply lift up the handle and the coupler socket will automatically release its grip on the ball.


Demco EZ-Latch in Use

The contoured, low-profile design of the latch handle helps protect the coupler from damage by allowing any potential hazards - from debris on the road to your ball mount backing into the coupler - to simply slide over the top. This helps prevent anything from getting under the latch handle and releasing the ball, and it can also limit any damage to the coupler should an impact occur


Unlike most couplers, which have a pin hole on the handle latch, the EZ-Latch coupler features a hole on the side of the coupler itself. Inserting a coupler lock through this hole will keep the latch from lifting, preventing disconnect and theft.


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.


Sturdy, Corrosion-Resistant Construction

Made of sturdy steel, this hydraulic trailer brake actuator features a durable zinc coating that is designed to limit rust and corrosion. This zinc coat has a 120-hour salt spray rating. In addition, the composite master cylinder is made of corrosion-resistant glass-reinforced nylon to further ensure durability.

It was delivered very quickly and on my doorstep. I bought this to put on a Tow Dolly I purchased to pull my car behind my motorhome. The surge brake will make it much safer going through the mountains on my way south. I also feel the price was great.

Excellent support from Nicole in helping me confirm availability of all my material needs for my boat trailer brake upgrade from Drum to Disk. Have not actually done the install but parts arrived a day early and look to be high quality. This actuator is a perfect fit to replace my old drum brake surge actuator. Thanks Nicole!!

Ask the Experts about this Demco Brake Actuator



  • How Does Reverse Lockout Solenoid of Demco Surge Actuator # DM62VR Wire Up
    The reverse lockout solenoid wiring of your # DM62VR is not polarity specific. This means that you can use either as the power wire or the ground from your reverse light circuit. As long as one has power and the other ground you are good.

  • Weight of Demco Hydraulic Brake Actuating Coupler
    Minus the packaging, the Demco # DM62VR Hydraulic Brake Actuating Coupler weighs about 18 lbs. The coupler is compatible with trailers weighing up to 7000 lbs with disc brakes. The coupler fits a 2 inch trailer ball, and is equipped with an electric lockout solenoid that will prevent the brakes from engaging when the tow vehicle is shifted into reverse, assuming that the coupler is installed correctly and the center pin of the 7-way on the tow vehicle is tied into the reverse lamp circuit.

  • Correct Replacement for Disc Brake Demco DA66B Actuator
    The correct replacement for a Demco DA66B Actuator is the Demco Hydraulic Brake Actuator part # DM62VR. This will be a direct bolt-on replacement for the existing model, no drilling required. It uses a three hole pattern but the two holes will match the ones you have now and you can choose to drill the third lower hole or just use the top two. There are only two required. The brake line fittings will be the same.

  • Troubleshooting Demco Hydraulic Brake Actuator # DM62VR
    I spoke to my contact at Demco and he told that the Demco Hydraulic Brake Actuator # DM62VR should not slam forward when you slow down. He said this brake actuator is inertia based, meaning as you start to apply the brakes it will begin to slowly activate your trailer's brakes. It should not be where the brake actuator slams forward as you say. There are a couple of things he said that could be causing the problem. The first thing he said could be the issue are the bolts that hold the...

  • Recommended Surge Brake Actuator To Replace Discontinued Atwood 61101 on Pacific Boat Trailer
    For a replacement for your Atwood 61101 I recommend the Demco Hydraulic Brake Actuator # DM62VR. This actuator is designed to work with disc brakes and fits a 3" wide trailer tongue with bolt holes 3" apart on center. It comes with an electric reverse lockout and uses an EZ-Latch coupler for a simple hookup and disconnect. It also features a zinc plating finish for corrosion resistance. I have attached a review video for your reference.

  • Do I Need A Brake Actuator With Electric Lockout If I Want To Back Up My Boat Trailer
    It depends on if your boat trailer has free-backing brakes. These brakes will allow you to drive in reverse without the actuator activating your trailer's brakes. The Demco Hydraulic Brake Actuator - Drum - Zinc - 2" Ball - 7,000 lbs, part # DM72VR, will work if you have the free-backing brakes. If not, you will need Demco Hydraulic Brake Actuator w/ Electric Lockout - Disc - Zinc - 2" Ball - 7,000 lbs, part # DM62VR. I have included a product description link and video demo links below.

  • Recommended Replacement Surge Brake Actuator for Karavan Boat Trailer
    I was able to do a little bit of research and it looks like the Karavan trailer you're referring to had a 7000-lbs surge actuator. To replace that I recommend using the Demco Hydraulic Brake Actuator w/ Electric Lockout - Disc - Zinc - 2" Ball - 7,000 lbs # DM62VR, which will bolt onto a 3" wide channel tongue and gives you a durable zinc-plating that's going to stand up to rust and corrosion really well. This actuator has an electric lockout to allow for backing up without engaging the...

  • Replacement for Atwood Surge Brake Actuator 85778
    The replacement I recommend for an Atwood Surge Brake Actuator 85778 is the Demco Hydraulic Brake Actuator part # DM62VR. It has the same ball size, offers a bolt-on install, and has a greater capacity. The only difference is it has an electric lockout as opposed to a manual one.

  • Actuator/Coupler Replacement for 85841 on Sea Ray Boat Trailer
    Since your trailer has disc brake it will be very important that you pick out a actuator/coupler that is rated for that and not drum brakes as that is a lower pressure rating that won't work well. The 85841 is no longer made so it would be tough to find so I would recommend going with a new coupler setup like the # DM62VR which you could bolt onto your frame once you cut off the older welded on model. If you wanted to weld this in place of what you have you certainly could do that as well.

  • Recommended Surge Brake Coupler To Replace Older Atwood Actuator W/ Bad Master Cylinder
    I have a replacement option for you, but since Atwood went out of business there is not longer any replacement 171 master cylinders, and there is not a different brand master cylinder that will work as a replacement. Instead I recommend replacing your coupler with the Demco Hydraulic Trailer Brake Actuator - Drum Brakes - Zinc Plated - 2" Ball - 7,000 lbs # DM72VR if your 1996 Jayco trailer has drum brakes, or # DM62VR if your trailer has disc brakes.

  • Can the Demco 8705101 Be Used With Drum Brakes
    Since the Demco Hydraulic Brake Actuator w/ Electric Lockout - Disc - Zinc - 2" Ball - 7,000 lbs # DM62VR is designed specifically for disc brakes you will not be able to use this for your drum brakes. This actuator will provide more fluid pressure when compared to one made for drum brakes. What you are looking for is the Demco Hydraulic Brake Actuator - Drum - Zinc - 2" Ball - 7,000 lbs # DM72VR. The Demco part is 8705001, it is the drum brake equivalent of the 8705101 you purchased....

  • What Surge Brake Actuator Is Recommended For My 3,500 Lbs Jayco 1206 Camper
    My recommendation is the Demco Hydraulic Brake Actuator - Drum - Zinc - 2" Ball - 7,000 lbs, part # DM72VR. It is rated for 7,000 lbs and it has Demco's EZ-Latch Coupler. This actuator does not have a reverse lockout, so your trailer would need free-backing brakes. This is so you do not activate your trailer's brakes while driving in reverse. If you need an actuator with a reverse lockout, my recommendation is the Demco Hydraulic Brake Actuator w/ Electric Lockout - Disc - Zinc - 2" Ball...

  • Replacement Surge Brake Coupler For An Older Atwood Master Cylinder
    Since Atwood went out of business, replacement Atwood 171 master cylinder's and replacement parts are not available. Instead, your best option is to replace the entire coupler with # DM72VR if you have drum brakes, or # DM62VR if you have disc brakes on your 1997 Jayco Tent Trailer.

  • Recommended Replacement for a Fulton A60 Surge Brake Actuator
    The Fulton A60 Surge Brake Actuator is obsolete so you'll need to replace the entre unit for which I recommend using the Demco Hydraulic Brake Actuator part # DM72VR for drum or part # DM62VR for disc. The Demco actuator has a 7,000 lb rating which is 1,000 lbs more than the existing and uses a 2" hitch ball. It features a simple three bolt pattern but you'll likely have drill new holes to attach as we won't have anything that matches up with the A60. The EZ-Latch mechanism makes hookup...

  • Solution for Needing Replacement Atwood Actuator Master Cylinder
    Atwood has been out of the coupler business for long enough that there are no longer any replacement master cylinders for their actuators. Since no other brand of master cylinder fits the best option is a new coupler/actuator with the # DM72VR for a drum brake application or # DM62VR for a disc brake application.

    Yes, I have a couple of brake actuator options to replace your Atwood. These couplers are both the same size and will fit right in to your 3-1/2" coupler opening. Depending on what type of braking system your trailer has you will either need the Demco Hydraulic Brake Actuator item # DM72VR for drum brakes. Or the Demco Hydraulic Brake Actuator w/ Electric Lockout item # DM62VR for disc brakes. The Demco Hydraulic Brake Actuator item # DM72VR for drum brakes does not have an electric lock...

  • Replacement Pontoon Boat Trailer Surge Brake Actuator With Drop Coupler
    I recommend using the Demco Hydraulic Brake Actuator w/ Drop and Electric Lockout # DM8750311. This actuator has a 4" drop that will help you attach to you truck without the need for such a large adjustable receiver. It will work with your single disc brake axle and features a electric reverse lockout like your current actuator. To this I recommend adding the Manual Reverse Lockout Kit # DM5939. This will allow you to disconnect the electrical and still ensure your brakes will remain...

  • Can Surge Trailer Brakes Compensate for Lighter and Heavier Trailer Weights
    The great thing about surge brakes like the Hydraulic Trailer Brake Kit # AKFBBRK-35 that you referenced is that since they use inertia to apply the trailer brakes they do compensate for differences in trailer weights. So if you had a heavier trailer they would apply harder and for a longer time than if you were to use a lighter trailer where the trailer wouldn't be pushing on the surge actuator as hard. Electric brakes offer more adjustability but they aren't self contained like the surge...

  • Replacement Actuator for Atwood Surge 85778 that Stopped Securing to Hitch Ball
    Your coupler is broken and is not latching to your hitch ball. This is somewhat common for the Atwood coupler that you have so it would be time to replace it since there are no repair kits for it either. The best replacement option we offer for an Atwood Surge Brake Actuator 85778 is the Demco Hydraulic Brake Actuator part # DM62VR. It has the same ball size, offers a bolt-on install, and has a greater capacity.

  • Is A Hydraulic or Surge Coupler Adjustable for The Weight of the Trailer
    A hydraulic or surge coupler isn't adjustable for the weight of the trailer but strangely enough, they don't need to be. The brakes would certainly be more effective if there were more weight on the trailer, but conversely a lighter trailer doesn't need as much braking force as a heavier trailer would. I've spoken with my contacts at Demco and Titan, both of whom confirm this. The more inertia provided by the weight of the trailer and its load, the harder the brakes will apply, but less...
