  • Maximum tongue weight: 700 lbs
  • 1-Year warranty


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 actuator is triggered as your trailer moves forward while the tow vehicle slows. The actuator telescopes, applying force to its master cylinder, which in turn supplies the necessary hydraulic pressure to engage the trailer's brakes.


Because this model does not include a reverse lockout, it is recommended that you equip your trailer with free-backing brakes so that you can drive in reverse without triggering your trailer's brakes.

Alex was easy to work with and knew exactly what I needed. Received the parts yesterday and everything was there. 5 stars 816041

Very nice hitch. Really like the drop and go part and works smoothly. Also like the large cap for checking brake fluid level and looks like it will last a long time (with proper use). Not like other hitch types that the cap and threads strip out due to corrosion. 811212

Ask the Experts about this Dexter Axle Brake Actuator

  • Replacement Surge Brake Actuator Recommendation for 1997 Eagle Spirit Boat Trailer
    Thanks for the picture of your trailer. From that I can tell that the replacement actuator # 099-175-00 is what you'd need. Three inch diameter axles are typically 5,200 lb but the highest rated hub/drum we have with a 5 on 4-1/2 inch bolt pattern like you have is 3,500 like the part # 84546UC3-EZ. If your drum measures 10 inch in diameter then this is the correct replacement most likely but it would still be a good idea to get the bearing numbers out of your hub so that we can verify...

  • Dico Surge Brake Actuator that Looks like Model 60 Replacement
    The best solution we have is going to be a new surge coupler like the # 099-175-00. Some of the Dico and Titan parts are interchangeable in recent years but since your trailer is almost 30 years old it's tough to say what all would still work. Plus you have to consider it's hard to know what all would need to be replaced so replacing the entire coupler gives you all new parts and frees you from having to worry about the next old part on the coupler that may wear out.

  • What to do Now That Atwood Replacement Master Cylinder 85739 is no Longer Available
    You're certainly not the first person to ask about the Atwood 85739 master cylinder but those replacement parts are simply no longer available which means your best option truly is to replace your actuator. I completely understand this isn't the news you were seeking but it truly is the best option at this point. An outstanding manufacturer of actuators is Titan and they have a number of possibilities; I recommend checking out the Dexter DX7.5 Drop-N-Go Brake Actuator - Disc Brakes...

  • Replacing Titan 60 Lever Type Latch With Electric Reverse Lockout for Drum Brakes Recommendation
    Yes, check out the Dexter Drop-N-Go Brake Actuator part # 099-175-00. This is a drum brake, model 60 style actuator with a 7.5k capacity, and is the replacement for the leverlock latch system. All that is missing is an electric lockout solenoid which can be purchased separately, part # T4748800. We have learned that in order to attach this solenoid to the master cylinder, the fitting that is currently on the master cylinder will need to be removed and the solenoid threaded directly on in...

  • Recommendation to Replace Atwood 83010 Brake Actuator
    Your existing Atwood model 83010 Brake Actuator (which as you mentioned is no longer available) is an 8,000 pound rated assembly for hydraulic drum brakes that's compatible with a 2" ball. It's designed to fit 3" wide straight trailer tongues. In terms of specs the closest option we have available for replacement is the Demco Hydraulic Brake Actuator # DM8669112. This actuator features an 8,000 pound towing capacity, works with 2 inch hitch balls, fits 3" wide trailer tongues, and is...

  • Replacement 7,000 lb Surge Brake Actuator for Drum or Disc Brakes
    We definitely have surge brake actuators that can work, but the ones we carry are mounted on top of your trailer's channel tongue and you will need to drill new holes in order to mount them. Additionally, please note that these actuators are each designed to fit 3" wide channel tongues, so to ensure the proper fit you are going to want to measure your trailer tongue. Dexter actuators are premium quality which is why I highly recommend them, and the correct 7,000 lb actuator that works...

  • Trailer Will Not Uncouple from Ball When Parked on an Incline
    Usually if you can move the tow vehicle and trailer to level ground, you can uncouple. However, sometimes you have to be on less than level ground. If the coupler will not come off of the ball in this situation, you can use the trailer jack to separate the coupler from the ball. What is happening is the pressure from being on an incline is putting enough force on the ball to make uncoupling very difficult. What you can do to help prevent this in the future is to make sure to properly...

  • Recommended Replacement for Model 70LP Surge Brake Actuator
    While we don't have replacement parts for a Model 70LP actuator, we do have a great replacement for it. Like the 70LP, these actuators are a fit for a 2" hitch ball, but they just have a slightly larger capacity at 7,500 lbs. You didn't mention whether you had drum or disc brakes so I'll give the options for both: - Drum Brakes: Dexter DX7.5 Drop-N-Go Brake Actuator - Drum Brakes # 099-175-00 - Disc Brakes: Dexter DX7.5 Drop-N-Go Brake Actuator - Disc Brakes # 099-175-20 I've added...

  • Reverse Lock Out Solenoid Recommendation for Dexter DX7.5 Brake Actuator
    The Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-00 that you referenced does not include a lockout system for backing your trailer, but an electric lockout solenoid, # T4748800, can be added to allow you to back the trailer. Along with the solenoid you may also want a shield, # T4835800183 which will help keep the solenoid undamaged.

  • Surge Brake Coupler Recommendation for a 1988 MAGIC Model MT Boat Trailer
    The Dexter Zinc-Plated Brake Actuator # 099-175-00 is the replacement for the Titan Leverlock actuator that you referenced. This replacement option by Dexter who bought out Titan is a stronger coupler with many similar components. This actuator has a new latch system that fits 2 inch trailer hitch balls. It will be a significant upgrade from your Atwood actuator.

  • Can a Lockout Be Added to the Dexter DX7.5 Drop-N-Go Brake Actuator
    Yes, you can use the Solenoid Valve for Titan Brake Actuators with Reverse Lockouts part # T4748800 on the Dexter DX7.5 Drop-N-Go Brake Actuator part # 099-175-00 to add an electric lockout feature.

  • Included Items for the Titan Zinc-Plated Leverlock Brake Actuator
    All parts you asked about are included with the Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-00. A reverse lockout solenoid valve like part # T4748800 is not required but may be needed along with the Solenoid Shield, part # T4835800183. These items will allow you to shift your tow vehicle into reverse and backup without activating the brakes on the trailer. I have included a link for the installation instructions which also includes a parts list for the brake actuator.

  • Comparing Demco and Titan Disc Brake Actuators with Electric Lockouts
    That is a tough question to answer as both are excellent manufacturers with their respective pros/cons. In regards to brake actuators, they both make and manufacture them here in the U.S.A. and they both come with a one year warranty. In regards to differences, Demco makes a wide range of different trailer and towing products whereas Titan specializes more in trailer brakes. WIth that being said we have had more positive feedback from Titan products in regards to trailer brakes, actuator...

  • Parts Needed To Install Brakes On Haulmark 8 Foot V Nose Trailer
    I did some research and it looks like most Haulmark trailers like yours have a 3,500-lb single axle. If you have different axles then let me know and I can make the correct recommendation.  Your axle must have brake mounting flanges attached behind the existing hub assembly on each side for brakes. If there are no brake mounting flanges then you will either have to replace your axle or purchase brake mounting flanges that can be welded to your axle by a qualified welder.  A common...

  • Replacement Coupler for Atwood Hydraulic Brake Actuating Coupler for Drum Brakes
    The Atwood brake actuating coupler number 61101 is no longer directly replaceable. Atwood has been bought out so I recommend replacing your actuator with the Titan Zinc-Plated Brake Actuator # T43397007K which can use # T4748800 as an electric lockout solenoid. This coupler has bolt holes that are 3 inches on center. I've attached a video to help further.

This does not include the electric lockout solenoid # T4748800. The brake line fittings will be the same. The Dexter DX7.5 Drop-N-Go Brake Actuator - 2" Ball - Zinc Plated - 7,500 lbs # 099-175-00 is also a great replacement option, and you can add the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 to this...

    You shouldn't have any problems with the Trailer Valet not staying vertical. If you have a surge brake actuator, like the Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-00 that doesn't have a reverse lockout, then the only problem that you will have is when you try to back the trailer up the brakes will engage. If you disengage the brakes then the Trailer Valet will work as it is intended to. Just be sure to re-engage the brakes when you are done moving your trailer. You can use either...

  • Difference Between Model 60 Surge Trailer Brake Actuators that Fit Disc and Drum Brakes
    Trailer drum and disc brakes require different psi ratings so that's why the part # T47154007K can only be used on disc brakes. Drums usually need 1,000 psi whereas disc needs 1,600 psi. For a version of this coupler that is designed for drum brakes you'd want the part # T43329007K. Or you can change out the master cylinders to fit the application. For a Model 60 actuator like this the part # T4820000 is for disc and part # T4395100 is for drum. To convert either actuator would only...

  • 3,500 lbs. Axle with Hydraulic Drum Brakes Kit
    I have a solution for you but unfortunately we do not carry any axles that come with hydraulic brakes. What you will need to do is buy the parts separately, but I have all the parts you will need. First, for an axle, you will need the Dexter Axle Beam with EZ Lube Spindles # T3584F-EZ-8974. This axle is 89" long with a weight capacity of 3,500 lbs. which is the same as the # 35545E-ST-EZ-89 Dexter Axle you were looking at. For your Hydraulic Trailer Brake Assemblies you will want...

  • Replacing a Dico Model 60 Actuator Recommendation
    We have a replacement for a Dico model 60 actuator. Dexter bought out Titan and upgraded that actuator replacing it with part # 099-175-00 which will be a great choice if your trailer has drum brakes. For disc brakes you'd want the part # 099-175-20. The part # 8605001 is a very similar option but it may not be an EXACT fit as it's not listed as a Model 60 replacement.

  • Availability of Corrosion Resistant Brake Assemblies for Boat Trailer
    Because electric brake assemblies like the etrailer.com self adjusting brake assembly part # AKEBRK-7L-SA are not typically used for boat trailers, the assemblies are not specially coated for saltwater corrosion resistance.

  • Swing-Away 2-Inch Drum Brake Actuator Coupler to Replace Discontinued Fulton A60
    The Fulton A60 series surge couplers are now obsolete and since parts are no longer available for them I suggest you replace the unit with a new brake actuator like the Dexter # 099-175-00 (drum) or # 099-175-20 (disc). This bolt-on coupler fits a 2-inch ball, mounts on a 3-inch wide channel tongue with bolt holes that are 3-inches on centers and is rated for 7500-lbs gross trailer weight.

Your brakes and hubs must match the axle rating. Next you'll want to take note of the size of the current brakes. You need to confirm the diameter and depth. You also want to note their mounting...

  • How to Determine if my Trailer Has Electric or Hydraulic Brakes
    Since you have an older trailer, the brakes could have possibly been switched from electric to hydraulic or the other way around. Even on newer campers, unless it is just purchased from the manufacturer, it would be just a guessing game for someone who cannot physically inspect it. The easiest way to determine whether your 1976 Wilderness trailer has electric or hydraulic brakes is by checking to see if it has an actuator or not.

  • Are There One-Time Use Electric Breakaway Kits for Trailers
    Aside from surge brake couplers like part # 099-175-00 (like you mentioned) we have never heard of a one-time use breakaway system. The only thing I can think of as to why you wouldn't want to test an electric breakaway kit, like the Hopkins # 20099, is because from my understanding in most states the battery must be able to lock the trailer brakes up for at least 15 minutes to be considered roadworthy. If you were to drain the battery completely by making sure they locked up for 15...

  • Difference Between Hydraulic Brake Coupler with Lockout and Without Lockout
    What a lockout on a hydraulic brake coupler does is prevent the brakes from applying when you back the trailer. An electric lock out is tied into the reverse lamp circuit on the vehicle so that when the vehicle is shifted into reverse the solenoid in the coupler is activated which prevents the trailer brakes from applying. If your boat trailer had free-backing brakes, you won't need a lockout because after being pushed a foot or so the brake assemblies disengage. For a 7500 lb hydraulic...

    I spoke with my contact at Fulton and they told me that the A50 coupler was for a surge brake 5,000 lb system and is no longer available. They said the parts for that are no longer available either. The coupler you will need depends on the kind of brakes you have on your trailer, either disc or drum. If you install a disc brake coupler on a trailer with drum brakes, you run the risk of having the brakes locking up. If you have disc brakes I recommend part # 099-175-20. This coupler...
