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.

by:

Original brake actuator was welded to the trailer tongue. I had to cut it back and weld a new piece of 3x3 tube steel and extend it out enough to install the new actuator. It lengthened the trailer by about a foot but worked out pretty well. The new one works great.



by:

Works as it should. If I had it to do over I would go with electric over hydraulic



by:

I have been looking to replacement for my Ezloader trailer. It was originally a TDE hitch but they don't exist. I had mistakenly measured my frame as 3 inch, but it was 3 1/4" inside. To make this work I did some sawing, welding, drilling and painting but it works better than original.



by:

This an almost perfect replacement for the original. I had to reroute the brake fluid line to met trailer line. Just got back from the lake a trip that had lots of mountains and we were impressed with how smoothly it worked.



by:

Anna was great at helping me confirm what I needed to order. I installed the Kodiak 10” disc brake kit, new lines and Dexter actuator with no trouble. I got rid of my rusty drum brakes that were a hassle to clean and maintain in salt water. Shipping was fast and my order was complete. I’d definitely recommend etrailer.com to friends!!



by:

solid actuator for a fair price. The auto latch feature is a nice feature.

YOU TOLD ME IT WOULD REPLACE A TIE DOWN TYPE TRAILER HITCH. IT DOES NOT.

This coupler would be a great replacement as long as your Tie Down fit on a 3 inch wide tongue with bolt holes that are 3 inches center to center. I will have our Customer Service team reach out to you.



by:

Very happy and it performs as expected. Using it with new disc braking system.
Getting used to putting the pin in before going in reverse, of course it can also be wired electronically, but haven't looked into that quite yet...



by:

I dove into this job of replacing my entire rusted out disc brake system on my double axle boat trailer having never done it before. Between the variety of part choices and accurate descriptions coupled with excellent phone service and on site videos, I was able to rebuild my trailer brakes system and suspension in total. I compared prices with the trailer manufacturer and found that etrailer either beat the price or matched it but I chose to give my business to etrailer because of the service! I do recommend this company and will use etrailer.com again anytime!



by:

I installed this as part of a disk brake retrofit to a tandem axle boat trailer that didn’t come with brakes. It was an easy swap from my factory coupler and connected fine to the flexible brake line kit. How to bleed the brakes wasn’t obvious from the instructions and YouTube videos are mostly out of date, but all it took was a long handled flat screwdriver to action the pump and apply pressure. The drop and go system is easy to use. I wish this model had a manual reverse solenoid lockout but the electric lockout has been working fine.



by:

The hitch is great. Disc brakes vs the drums I had before make noticeably more stopping power. My one regret is that while there is a backing lockout of the surge brake via a solenoid valve, for high mountain trailering, the surge brake stays applied when you’re descending in low gear. I smoked my brakes coming down from 5,500 ft last week, expelling a decent amount of high temp red bearing grease. I guess if steep mountain roads are the norm, maybe an electric brake overhaul would have been better.



by:

The unit is easy to install and is up and running in minutes.



by:

I changed the brakes on my 1995 boat trailer from drum to disc. I was able to figure out what to order on the etrailer web site. The whole project was relatively easy. I just had to remove the old parts and bolt on the new ones. The new trailer hitch actuator is much easier to used than my old one.



by:

Actuator is quality product. I was replacing a Tie Down 70E actuator that was 10 years old ( master cylinder and backup solenoid failed due to rust sediment buildup ?)
Be aware that the actuator does not come with mounting hardware so save yours from old unit
, also does not come with instructions-download from web.
The only noticeable difference between the newer and the old unit was the backup sensitivity.
The old unit needed the solenoid energized with just the trailer -the new unit didn’t need the solenoid energized with trailer and boat unless you were going up an incline(even with adjustment of the bolts joining the two pieces)
Overall very satisfied-as a side note both Tie Down and Titan were bought by Dexter Axle



by:

I have been ordering from etrailer.com for years and have not been disappointed. Their prices are great, they communicate the order status very well, and ship the products quickly.
I have been having ongoing issues with my trailer brake pressure not relieving, thus applying the brakes continuously. This order was for a new actuator which I believe will correct the problem. I just installed the actuator and it fit as expected.



by:

Super fast shipping & part was easy to install!



by:

Great selection of products with detailed product descriptions and very fast delivery. The information on the site was very helpful in identifying the replacement brake actuator that I needed for my 17 year old trailer. Installed in 20 minutes!



by:

Great product. I do wish is had a way to put a lock on it while attached to the tow vehicle.



by:

Works great! I wish I would have talked to a representative first. Bolt pattern didn’t match up with the old actuator, so I had to drill new holes. With my neighbors help got ur done in a couple hours. My fault. Thanks to etrailer for quick delivery as I needed to pull my boat out of the slip I was renting.



by:

BEST CUSTOMER SERVICE AND SHIPPING i HAVE EVER DELT WITH! EVERYONE THERE IS FANTASTIC!!! PARTS ARE GREAT TOO, NEVER HAD A PROBLEM WITH ANY!!! A+++++++++++++++



by:

Excellent product with good installation instructions



by:

Actuator works great. Very smooth stop. Well built.



by:

Amy was a great help got me what I needed right away and was shipped and received quickly thanks so much



by:

Your service was excellent and your price was very good.

Good service as well as fast shipping. Will be repeat customer.

  • 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 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...

  • Surge Brake Actuator Recommendation for Uhaul Tow Dolly Replacement
    If the tow dolly has disc brakes the Dexter DX7.5 part # 099-175-20 would be a really solid option that works great and is very reliable. Most dollies have disc brakes so this most likely is the one to use but if for some reason it had drum brakes we have this in a drum version with the part # 099-175-00. There isn't a super simple bolt-right-up actuator solution out there but this would be as close to that as possible and would work great so I'd recommend if for your Doug.

    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.

  • 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 Solution for Atwood 82542 Actuator on Boat Trailer
    Atwood stopped making actuators a while back which is why you aren't able to find a replacement or any replacement parts. So for a solution to replace what you have the Dexter DX7.5 part # 099-175-00 would be a great solution if you have drum brakes or the part # 099-175-20 for disc brakes. I really like how easy the coupler of these actuators work as basically you can just drop them onto the ball and they latch themselves.

  • Replacement For TDE-LP750 Trailer Actuator
    We can get you a good replacement, though there is actually no longer a TDE brand. But that actuator is simply a bolt-on, 7,500 lb actuator that couples to a 2" hitch ball, and per the owner's manual does not have a lockout (so it is for free-backing brakes). The replacement you can use is from Dexter, and the right one will depend on if you have drum brakes or disc brakes: - Drum: Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-00 - Disc: Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-20

  • Replacement Surge Brake Actuator For TDE Model LP 7000 On a 2013 Four Winns Boat Trailer
    I recommend replacing your Tie Down Engineering LP 7000 brake actuator with either the Dexter DX7.5 Drop-N-Go Brake Actuator for Disc # 099-175-20 or Drum # 099-175-00 brakes. This actuator has the same capacity at 7,500lbs and uses a 2" hitch ball.

  • Recommended Trailer Coupler With Breakaway Kit Replacement
    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...

  • Converting Trailer with Adjustable Ball Titan Model 60 Actuator to Alternative Style
    Since there isn't a way to convert your adjustable ball style of Titan Model 60 actuator to a leverlock style you'll need to remove the entire coupler and install the Dexter Drop-N-Go part # 099-175-20 if you have disc brakes or part # 099-175-00 if you have drum instead. This is the upgraded replacement for the Titan Leverlock. Dexter bought Titan and this is the new style I think you'll really like.

    While we don't have replacement parts for a Model 70LP actuator, we do have a great replacement for it.

  • Troubleshooting Corroded Master Cylinder on Titan Actuator 60 Model
    I spoke with my contact at Dexter/Titan and he said he doubts your actuator could have any serious rust build up in a month's time, certainly not enough to clog anything. He recommended cleaning the cylinder with an alcohol solution and paint brush making sure you slosh the alcohol around. It is fairly easy to remove the cylinder. Just remove the back cover, detach the line and loosen the four bolts. Most likely the problem is that the coupler is not fully extended. If it is not fully...

  • Can Surge Coupler Be Used on Boat Trailer With Electric Brakes
    From what you describe, it sounds like your trailer originally had hydraulic brakes that have been replaced with electric brakes. At this point, your hydraulic coupler which is also known as a surge coupler is strictly being used as a way to attach the trailer to the trailer ball. This arrangement works just fine as long as a cross bolt has been installed to prevent the coupler from being compressed. You won't need to use the mechanical breakaway, as it'll be inoperable anyway.

  • 2013 Road King Replacement Actuator.
    To replace your Tie Down Model 700 disc surge brake actuator the Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-20 would be a great option. It's galvanized to fight corrosion and has a latch design that is better so it doesn't get hard to use over time like others.

  • Is a 7-Way Round Connector Used to Activate Surge Brakes on Boat Trailer
    The surge brakes on your boat trailer operate completely independent from the trailer wiring/connector so there isn't a pin on the 7-way that activates the surge brakes. The wiring that your mechanic was speaking of is that used for an actuator with a reverse lockout solenoid, like part # 099-175-20. In this case you would need to run a wire from the reverse light circuit to the solenoid so that you can reverse your trailer without the actuator activating the brakes of the trailer.

  • Is the Dexter Drop-N-Go 099-175-20 a Good Replacement for an Atwood 61101?
    As Atwood is no longer in production, finding replacements can be a bit of a pain. That being said, the Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-20 will be a good replacement for your Atwood 61101. This will handle disc brakes and has a 7,500 pound capacity. From the pictures I could find, it looks like the # 099-175-20 may bolt right to the same bolts holes as the Atwood, but don't quote me on that as I don't have a way to confirm it..
