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:

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



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:

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.

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:

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



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:

Super fast shipping & part was easy to install!



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:

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



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:

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:

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.



by:

Actuator works great. Very smooth stop. Well built.



by:

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



by:

Excellent customer service. Great experience. I will definitely use them in the future.

  • 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.

  • 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.

  • Disc Surge Brake Actuator for Eagle 25 Trailer
    Since you said the trailer has a weight of around 4,000 lbs and has disc brakes the surge actuator you'd want is the Demco part # DM8605101 which is for disc brakes and has a 6,000 lb capacity plus has a reverse lock out to allow the trailer to back up without activating the brakes.

  • 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..

  • Replacing A TDE Model LP7000 Actuator
    The Dexter drop-n-go # 099-175-20 would definitely have the same capability as your TDE actuator, provided it is a disc brake setup. TDE is no longer in business so I'm afraid finding a direct replacement will be impossible. My main concern is the design and shape of the tongue. The Dexter actuator, along with the others we carry, are designed to go over the tongue and will fit a 3" wide tongue. Since your trailer was designed for a TDE actuator, the tongue is likely wider than 3". We do...

  • Solution for Using Dexter Drop-N-Go Brake Actuator with 2-5/16 inch Hitch Ball
    Dexter does not offer a version of the Drop-N-Go brake actuator like the # 099-175-20 with a 2-5/16 inch hitch ball. It would probably be the easiest if you swapped your hitch ball size from 2-5/16 inch down to 2 inch so that you'd be able to use this coupler. I attached a link to a page that has all of the 2 inch hitch balls we carry as well. You'll want to select your shank diameter (the hole in the ball mount the ball fits through) and you'll see all options that fit.

    If you are wanting to replace the entire surge brake actuator on your Four Winns Horizon 190 boat trailer then I have exactly what you will need.

  • Why Arent Surge Brake Actuators Adjustable
    I can probably track down some instructions for the Dexter part # 099-175-20 but if your main concern is adjustability I can answer that right now and say no there is no adjustability. What you get is what you get with surge brake systems, but the good news is braking is somewhat proportional as the harder the trailer presses (heavier the trailer and/or harder braking) the harder the trailer brakes will apply. So you end up with pretty smooth braking but it's just not adjustable in any...

  • Can the Latch Mechanism Be Adjusted on the Dexter DX7.5 Drop-N-Go Brake Actuator
    I do have an option for you but there are no adjustments that can be made to the latch mechanism on the Dexter DX7.5 Drop-N-Go Brake Actuator part # 099-175-20. There are also no replacements parts for the latch so if the one you have is loose you'll need to replace the entire coupler so you can be sure the trailer is in safe, working order.

  • Replacing Titan Aero 6000 with Dexter Surge Actuator 099-175-20
    The Titan Aero 6000 does use a slightly different bolt pattern as the Dexter Coupler part # 099-175-20 so while it can work as a replacement you'd have to drill new holes or have the new coupler welded on. The brake line fittings are the same though so it would easily connect in that regard without requiring any adapters or fittings.

  • 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. We don't have any leaf springs that match the capacity and length you need though.

  • 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.
