Features to know about
Backing Up Without Brake Lockup: Built-In Electric Lockout
Backing up a loaded trailer can be tricky if your brakes grab when you shift into reverse. The Demco Hydraulic Brake Actuator w/ Electric Lockout takes care of that automatically. The built-in solenoid ties into your reverse light circuit so the brakes stay disengaged when backing up. There’s no need to get out and flip a lever or use a manual lock pin. It’s a simple, automatic fix that makes reversing a boat, utility, or construction trailer much easier.
Confident Hookups Every Time: EZ-Latch Coupler for a 2" Ball
The EZ-Latch coupler makes connecting quick and foolproof. Just lower the coupler onto the 2" hitch ball and it locks itself in place with a solid click. You don’t have to hold the latch open or guess whether it’s seated correctly. The nylon composite latch handle is tough and corrosion-proof, so it won’t bend or snap like metal handles can. A locking pin can be added through the side hole if you want an extra layer of security when parked.
Reliable Braking for Heavy Loads: 7,000 lbs GTW Disc Brake Design
This actuator is rated for 7,000 lbs gross towing weight and is built specifically for hydraulic disc brakes. It delivers the higher fluid pressure that disc systems need—something drum actuators can’t do properly. A glass-reinforced nylon master cylinder with a large reservoir keeps more brake fluid on hand and helps prevent contamination thanks to the automotive-style diaphragm cap. It gives you smooth, consistent braking even on long hauls or steep grades.
Smooth Operation That Lasts: Self-Lubricating Liner and Heavy-Duty Steel Build
Inside, the inner member glides on a wear-resistant, self-lubricating plastic liner that keeps movement smooth and quiet mile after mile. Large rear rollers help it telescope easily as the trailer moves with your vehicle’s braking and acceleration. The actuator body is made of heavy-duty steel with zinc plating that resists rust, backed by a 120-hour salt spray rating—ideal for boat trailers or any setup exposed to moisture and road salt.
Straightforward Installation: Bolt-On Fit for 3" Channel Tongues
Mounting is simple thanks to its standard bolt pattern designed for 3" wide trailer tongues. It uses 1/2" x 4-1/2" Grade-5 bolts (not included) for a solid fit you can trust. A built-in breakaway cable with snap hook comes ready to connect, giving you automatic trailer braking if it ever becomes disconnected in transit. Once bolted on, this Demco actuator is ready for years of dependable use with minimal upkeep.

The bottom mounting hole is Too Close to the bottom flange. I could not get a socket on the bolt because the spacing at the bottom would not allow it. The only wrench capable of getting at the bolt head is a 3/4" open end wrench. I don't know about YOUR toolbox, but mine does not have a 3/4" open end wrench with torque readings. I could grind the flange a bit, but that would destroy the galvanized coating. I'll live with it as tight as I could get it, but this
is a design flaw.

This trailer hitch brake actuator is excellent! My 2001 Jayco Eagle pop up has a stock hitch that was terrible. Upgrading to this will make hook up and detach way easier. Attaching this where the stock hitch went took some doing, had to grind off the tabs at the bottom of the frame to fit better, but the screw holes on the actuator align with the holes on the frame. The lift Jack also had to be moved back 8” to accommodate the rest of the actuator. Worth it for the peace of mind. Would buy again!

Having peace of mind is always worth it in my opinion, Ariel! Have you taken the pop-up out for a trip with the new actuator on it yet to test it out?
Gwendolyn Y.

@Ariel I totally agree with the EZ-latch! It makes hitching up so much easier and takes out the guess work of if its actually latched down all the way. We have an old trailer here at etrailer we use for all kinds of things and each time we need to hitch it up, we all struggle with the latch.
I'm glad it worked out so well for you!

The Demco brake actuator pulls pretty smooth for a surge brake setup. One issue is the lip on the bottom of the unit. When installing a bolt, the head of the bolt hits it when tightening down. Can't use a washer on that bolt because of that.

- Surge Brake Actuator Replacement Recommendation for Atwood Model 84132Since Atwood went out of business none of their actuator (or other product) replacement parts are available unfortunately, so your only real option to having a working actuator is to replace the entire unit. I am attaching a link to our selection of replacement surge brake actuators that you can check out. If you can give me some more details about your Atwood actuator and send a few pictures in I can try to help you choose the best replacement option.

- Recommended Replacement for Atwood Surge Brake Actuator 85778The manual lockout on your Atwood 85778 surge brake coupler is there so that you can back up the trailer without the brakes locking up on you. Yes you can safely tow your trailer with the broken manual lockout, you just have to make sure you don't put yourself in the situation where you have to back your trailer up. Since Atwood went out of business there aren't any exact replacements for your coupler but you can use a different brand. The only thing I was able to find online about the...

- Troubleshooting Surge Brake Boat Trailer that Makes Slamming Sound When Hitting BumpsIs your trailer sitting as level as possible? Sounds like it could be sitting possibly nose high and combined maybe with a bit of play in the ball mount is creating the slamming you are experiencing. It's also possible your surge actuator has a bad shock and the bump is causing the actuator to apply and release the brakes quickly which is causing what you described. If you can push in on the front of the actuator you should be able to see the actuator somewhat slowly rebound to the fully...

- How to Wire Reverse Lock Out Solenoid on Hydraulic Trailer Brake Actuating CouplerI don't have a wiring diagram, but I'd be happy to explain it for you. In order for the reverse solenoid on a Hydraulic Brake Coupler like # DM62VR to function, one of the two wires leading from it needs to be connected to the wire from the center pin of the trailer connector, which is typically the yellow or purple wire (use a circuit tester like # PTW2993 to confirm). The remaining wire is grounded to the trailer frame. On the vehicle side, you'll need to make sure that the center...
view full answer... - Converting From Hydraulic Drum Brakes to Disc BrakesHi Mike; can you send me your axle information? Is it a 3,500 lb axle? If I had to guess it is likely a 3,500 lb axle on there right now. Assuming you have the standard 3,500 lb bearing combination you can use the DeeMaxx Disc Brake Kit # DE66YR. This uses # L68149 inner and # L44649 outer bearings. You already have the hydraulic lines so the only other thing would be an actuator for disc brakes. Assuming you want a coupler for a 2" ball and have a 3" wide tongue the # DM62VR you looked...
view full answer... - Disc Brakes for 2022 Road King Boat Trailer With Dexter Vortex HubsHey David! For a disc brake conversion I recommend the DeeMaxx Disc Brake Kit # DE42FR. These are designed to fit a 5 on 4-1/2 bolt pattern and are rated for 3,500 lb axles. Make sure this matches your axle capacity. They are also compatible with your Dexter Vortex hubs. This is a pair of brakes so you will need a quantity of two with tandem axles. For a surge brake actuator I recommend the Demco Hydraulic Brake Actuator w/ Electric Lockout # DM62VR. You will also need the Kodiak Hydraulic...
view full answer... - Replacement Disc Brakes and Actuator for Magnum Boat TrailerHey Michael! It sounds like that is a UFP H-1377 which would be a 3,500 lb hub using the standard bearing combination. I'm guessing you have slip on rotors based on that information. If you want to use the existing hubs the DeeMaxx Disc Brake Kit # DE42FR is the best option. If you want to go ahead and replace everything I recommend the Kodiak Disc Brakes # KOD87FR which cost a little bit more. Disc brakes are always on the higher end, these are the most budget friendly available. I don't...
view full answer... - Replacement Actuator for Atwood on 1987 EZ Loader Boat TrailerHey Brian, 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. Was the Atwood working from 1987 till recently?
view full answer... - Trailer Coupler Needed To Convert To Electric Over Hydraulic Brakes Hey Kelvin, From what I can find the Titan Model 6 brake actuators have their bolt holes almost in a straight line at the bottom of the coupler so you would have drill new holes in order to mount a new brake actuator. It also shows the Model 6 having a 2-5/16" ball coupler so the Demco # DM62VR and Dexter # 099-175-20 wouldn't be the right choice. If you're wanting to switch to electric over hydraulic then you'll want to go with a standard coupler like the Demco Channel Tongue Trailer...
view full answer... - How to Add Brakes to Older Demco Kar Kaddy 3Michael, to add brakes to your Demco Kar Kaddy 3, you can use the Kodiak Disc Brake Kit # K2R35D. This will allow you to slide the rotor over the existing idler hub, and the brackets for the caliper will bolt to the brake mounting flange. You will also need to ensure that you have this type of flange on your tow dolly otherwise you may not be able to add any brakes to the system. You will also need the the Demco Hydraulic Brake Actuator # DM62VR as well as the Demco Hydraulic Brake Line...
view full answer... - Replacement Drum Brake Actuator for a Atwood 85778 Hey Ashley, thanks for the information! To replace a Atwood 85778 brake actuator, I recommend the Demco Hydraulic Brake Actuator item # DM62VR for drum brakes. It has the same 2" ball size and offers a bolt-on install for a 3" wide straight tongue. Please note that the Demco Hydraulic Brake Actuator item # DM62VR has a manually lock out. If your boat trailer does not have free backing brakes, you can install the Reverse Lockout Solenoid Kit item # DM5836 which will automatically engage...
view full answer... - Recommended Disc Brake Hubs, Lines, and Hydraulic Actuator for a Boat Trailer w/a 3,500 lbs AxleHey Wendell! Thanks for getting back to me with all that information! I recommend the Kodiak Disc Brakes - 10" Hub/Rotor item # KOD67FR. These hubs have a corrosion-resistant Dacromet finish that stands up great in both freshwater or saltwater. The hubs have a 5 on 4-1/2 lug pattern and work with 13" and larger wheels. For brake lines and fittings you'll want the Kodiak Hydraulic Brake Line Kit - Single Axle - 18' item # 18SI-BLKIT. The Demco Hydraulic Brake Actuator w/ Electric Lockout...
view full answer... - Does Actuator of Trailer Coupler Need to be Replaced Going from Drum to Disc BrakesHey Mike, yes the actuator of your trailer would need to change to go from drum brakes to disc brakes because disc brakes require a lot higher pressure than drum brakes. BUT you might have an actuator that can have the master cylinder replaced with one that is for disc brakes so that would be a little easier. Either way the Demco part # DM62VR would work as a complete replacement to work with your disc brakes. Do you have the disc brake components picked out already?
view full answer... - Parts Needed To Add Disc Brakes To A 2002 EZ Loader Trailer With No BrakesHey David, thanks for reaching out. The Dexter Premier Disc Brake Kit # T2HRCM10DAC will work for you, provided your EZ Loader trailer is equipped with a standard 3,500 lb axle. There isn't a way to look up that information using the VIN, so you'll definitely want to get under the trailer and check the axle tag/sticker and confirm this. If you can't make out the axle sticker, you'll need to pull a hub and make sure the bearings are the standard # L68149 (1.378" inner diameter) inner bearing...

This would be my best recommendation at this time but if you wanted something more like what you have I'd need to see a picture or know the model of the TDE actuator you have as there are a few options out there.
view full answer... - Can The Demco Hydraulic Brake Actuator DM72VR Be Used With Disc Brakes? Hey Doug, thanks for reaching out. So the # DM72VR actuator you mentioned is only for drum brakes, you can't use it with disc brakes. If you want to run a disc brake setup, you need to use the # DM62VR actuator instead. They operate at a different PSI. That said, I see you already ordered the # DM72VR drum brake actuator, so if you intend to use that we should definitely have a drum brake kit for you, but I'll need a bit more information in order to be sure you are getting the right thing....

We've found that they are very reliable and do a great job applying the trailer brakes. Way better than the now discontinued Atwood actuator you have that was known for problems. This part number is for drum so for a disc version you'd want the # DM62VR and you'd be set. This comes with an electric reverse lockout as well. Now I don't know your axle capacity or wheel bolt pattern so I am not able to give...
view full answer... - Recommended Disc Brakes for a Boat Trailer Hey Wendell. I am going to need to know your bearing numbers or spindle size, axle capacity, how many axles you have, length of the trailer, and your lug nut pattern. I have linked an FAQ below that'll show you how to measure your lug nut pattern. To find the bearing numbers or spindle size, you'll want to pull one of the hubs and look at the two bearings. They should have numbers stamped into the sides of them. I'll need those part numbers to identify your spindle size which will tell...

The options we offer in this category would either come with an electric lockout and without but there unfortunately aren't any with a manual lockout option. You could go with the Demco Hydraulic Brake Actuator w/ Electric Lockout # DM62VR and use the Tow Ready 4 Pole...

Or one of the Demco Hydraulic Actuator item # DM72VR for Drum or item # DM62VR for Disc brakes that mount over the top. If you could comment below with a part number off of your current...

The spindle on the Timbren system is correct for those disc brakes, and the bearing kit is also correct. So you can use each of the following: - Timbren Axle-Less Trailer Suspension - 4" Lift - 5,200 lbs # TASR5200S03 - Kodiak Disc Brake Kit # K2HR526DKG - Timken Bearing Kit # TMK32VR As for the actuator, the type you asked about isn't something that we offer; in fact I'm not sure if that type (if I'm correctly...

The part number F47260K comes back as the master cylinder for a TDE model 66, 70 and 80 disc brake actuator. It sounds like yours may be the model 70, and if so, the Dexter # DX56FR can be used to replace it. This is designed to bolt onto the end of the tongue. If you need one that drops onto the top of the tongue I recommend the Demco # DM62VR instead. Both are rated for use with disc brakes and have a max capacity of 7,500 lbs.

This is the actuator we recommend most to replace the now discontinued Atwood actuators and the feedback has been great.
