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.

The actuator was just what I needed. Now just have to bleed the brakes. The lock will prevent anyone from driving off with my boat or trailer.

Works great!!!

- 099-175-00

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.

Ask the Experts about this Dexter Axle Brake Actuator

  • Recommended Surge Brake Actuator For Discontinued Atwood 85739
    You are correct that the Atwood 85739 has been discontinued along with all of the replacement parts for it. I recommend replacing it with the Dexter DX7.5L A-60 Brake Actuator w Electric Lockout - Weld On - Disc - 2" Ball - Primed - 7.5K # DX63FR if you have disc brakes or # DX53FR if you have drum brakes. I included videos of the products mentioned for you to take a look at.

  • 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...

  • 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.

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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.

  • Included Items for the Titan Zinc-Plated Leverlock Brake Actuator

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.

Instead I recommend the Titan Zinc-Plated Brake Actuator - Drum - Lunette Ring - Bolt On - 8,000 lbs # T4093200 which has a slightly higher trailer rating at 8000lbs, is designed for drum brakes, and includes a lunette ring...

  • 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...

  • Replacement Coupler for Atwood Hydraulic Brake Actuating Coupler for Drum Brakes
    The Atwood brake actuating coupler number 61101 is no longer directly replaceable.

This coupler has bolt holes that are 3 inches on center. I've attached a video to help further.

  • 2005 Ranger Trail Boat Trailer Replacement Hydraulic Brake Coupler
    Was there any manufacturer info on the existing coupler? Any part numbers? Unfortunately, there isn't an existing database that allows me to look up which hydraulic coupler was originally used on your 2005 Ranger Trail boat trailer. This being said, the Dexter Axle DX7.5 Drop-N-Go actuator would work well if you have a 3 inch wide pole tongue and need a coupler compatible with a 2 inch ball. For disc brakes, use the # 099-175-20, or # 099-175-00 for drum brakes.

  • 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...

  • 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...
