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.

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.

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!!

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.

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!

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

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.

Ask the Experts about this Dexter Axle Brake Actuator

  • Can the Titan Aero 6000 Surge Brake Actuator Be Repaired Or Should It Just Be Replaced
    For a Four Winns Boat Trailer with Titan Aero 6000 Surge Brake Actuator, I recommend replacement using the Titan Zinc-Plated, Leverlock Brake Actuator part # 099-175-20 which is ready to go as is and will be a great fit. The reason I recommend replacement is because of the availability of spare parts. Although we do have the Replacement Damper part # T4502000 and Replacement Master Cylinder part # T4395100 (Confirmed for Aero 6000), there are still several other smaller parts that could...

  • Replacement Actuator For Older Tie Down 70LC
    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....

    The best way to lock and secure the Dexter DX7.5 Drop-N-Go Brake Actuator part # 099-175-20 while not in use would be to use a wrap-around coupler lock like the Blue Ox Trailer Coupler Lock part # BX88351.

  • Surge Brake Actuators to Replace Atwood on Trailer
    The Demco Actuator part # 099-175-20 is a really great option for if you have disc brakes or if you have drum the part # 8605001. These can be welded on in place of your Atwood and in my opinion a better design than the Atwood surge actuators.

  • How to Convert from Hydraulic Drum to Hydraulic Disc Brakes on a Boat Trailer

  • 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...

If they are I recommend the Dexter DX7.5 Drop-N-Go Brake Actuator # 099-175-20.

  • Converting Boat Trailer Brakes From Surge Drum Brakes To Surge Disc Brakes
    If you are looking to use your Demco brake actuator you need to make sure it is compatible with disk brakes. Some actuators will only work with drum brakes because drum brakes do not require as much "pound per square inch" of fluid as a disk brake set up does. If it does not then you have to replace the actuator. I recommend Dexter DX7.5 Drop-N-Go Brake Actuator - Disc Brakes - 2" Ball - Zinc Plated - 7,500 lbs Item # 099-175-20. It is a bolt on application with the reverse lockout feature,...

  • 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...

  • How to Bleed Brake Lines with Titan Model 60 Hydraulic Brake Actuator Without Electric Lockout

You do not need an extra fitting when you use the actuator. If you ever need to replace the fitting, it is part # T4750300. I recommend Kodiak Brake Line for Single Axle trailers part # 18SI-BLKIT. The flexible line of the Kodiak kit has a thread size of 3/8"-24 and fits a 3/16" fitting like the...
