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.

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!!

  • Replacement Surge Brake Actuator For Atwood 61101
    Atwood is no longer in business, which means replacement parts are unfortunately no longer available for your Atwood 61101 surge brake actuator. The best option available if yours is no longer working is to replace the actuator, which you can do with either of the following models, depending on if you have drum brakes or disc brakes. - Drum Brakes: Demco Hydraulic Brake Actuator # DM72VR - Disc Brakes: Demco Hydraulic Brake Actuator # DM62VR Both of these actuators are bolt-on...

  • What Is The Difference Between A Disc Brake and Drum Brake Surge Brake Actuator?
    The difference between the Demco # DM62VR for disc brakes and the Demco # DM72VR for drum brakes is the pressure each one operates at so that why they cannot be interchanged. Disc brakes require 1600 PSI where drums like what your trailer has require around 1000 PSI. For a surge brake actuator compatible with drum brakes and a reverse lockout solenoid I recommend going with the Dexter DX7.5 Drop-N-Go Brake Actuator - Drum Brakes - 2" Ball - Zinc Plated - 7,500 lbs # 099-175-00 which...

  • 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.

  • 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.

  • Disc Brake Compatible Replacement for Tie Down Model 660 Surge Brake Actuator
    In regards to surge brakes, disc brakes require a much higher psi than drum brakes for proper operation therefore the two types of brake actuators (disc/drum) are not cross-compatible. The Demco Hydraulic Brake Actuator part # DM62VR would be a great disc brake compatible replacement for a Tie Down Model 660. It has an electric lockout which you can use to prevent the brakes from locking up while in reverse but it does not have to be hooked up.

  • 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.

    I would be happy to help! Based on the pictures you provided your trailer uses the discontinued Tie Down Engineering 70LC, and we will need to get a bit creative on a replacement as there is not a direct replacement available. What you will need to do is use the a folding tongue kit like the Fulton Fold-Away Coupler Hinge Kit for 3" x 4" Tongue - Bolt On - Up to 7,000 lbs # FHDPB340301, but you will first need to measure the size of your trailer tongue.

  • Recommended Surge Brake Actuator To Replace Atwood 82541 On 1098 Trail-Rite Boat Trailer
    To replace the Atwood 82541 surge brake actuator on your 1985 Trail-Rite boat trailer with drum brakes I recommend the Titan Zinc-Plated Brake Actuator - Drum - Multi-Fit Ball - Bolt On - 7,000 lbs # T43397007K which will fit your 3" wide tongue perfectly, and has the same 3" bolt pattern as your current actuator.

  • 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...

  • 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.

    We have exactly what you are looking for. Based on my research your Tie Down 70LC has a 7000lb rating and uses a 2" hitch ball. If your trailer has drum brakes I recommend the Titan Zinc-Plated Brake Actuator - Drum - Multi-Fit Ball - Bolt On - 7,000 lbs # T43397007K and if you have disc brakes I recommend the # DM62VR instead. Both of these options will bolt on to your 3" wide channel tongue. The # DM62VR includes and electric lockout solenoid but the # T43397007K does not....

  • Parts Needed To Replace Hydraulic Drum Brakes W/ Hydraulic Disc Brakes On Karavan Boat Trailer

Now the Kodiak Disc Brake Kit - 12" Rotor - 6 on 5-1/2 - Dacromet and KodaGuard - 5,200 to 6,000 lbs # K2R526DKG you mentioned will go over the idler hub and the included bracket will mount the caliper to the 5 bolt flange on your axle.

  • Recommended Replacement Surge Brake Actuator For Atwood 85778 For Drum Brakes or Disc Brake Upgrade
    You are correct that parts are no longer available for your Atwood 85778 brake actuator. I recommend the Demco Hydraulic Brake Actuator w/ Manual Lockout # DM8760011 as a replacement if you wish to keep your drum brakes. A Demco Trailer Coupler # DM12688-95 will attach to the 3" channel on the actuator for a 2" ball connection. It really comes down to if you are happy with the performance of your current drum brakes. I like seeing disc brakes used in heavy duty applications, on...

  • 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...

  • Adding Hydraulic Surge Brakes To a Demco Tow Dolly
    Rather than installing hydraulic drum brakes you should look at a Kodiak Disc Brake Kit # K2R35D for your tow dolly. That is the style the new Demco Kar Kaddy X Tow Dolly # DM9713093 uses as it would make for a much better setup that will be easier to install. The Kodiak Disc Brake Kit # K2R35D will allow you to slide the rotor over the existing idler hub. The brackets for the caliper will bolt to the brake mounting flange. You will need to ensure that you have this type of flange on...

    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.

  • Parts Needed to Tow a 2014 Jayco Jay Flight With a 2003 Ford F-150
    The brakes on your 2014 Jayco Jay Flight will depend on how it was originally equipped and if it was altered at some point. With that being said, it is pretty easy to tell which you have by looking at the coupler on the trailer. For hydraulic brakes, you will either have a surge coupler, like # DM62VR, or an electric over hydraulic system like # HBA-12. The # HBA-12 will use a 7 Way harness, but the # DM62VR may use a 4 Flat, 5 Flat, or 7 Way. These systems can also use either a disc...
