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.

Electric reverse lockout with solenoid is automatically activated when the tow vehicle is shifted into reverse. To use this feature, you must have a 5-pole flat, 6-way round or 7-pole wiring harness.

This total break overhaul was actually fun to do because i got everything from etrailer and I knew it was a perfect fit! One year and thousands of miles later I still love it. If your on the fence, take the plunge, you WILL be happy.. Trailer a 25ft 6500 lb boat up an down the East coast in salt water.

Not sure of actual product performance yet. But you guys really need to add a small instructional sheet. Wasted half an hour trying to figure out fittings before I finally figured out that since reverse solenoid was not attached it replaced the fitting already on the cylinder. Then after I had it together I saw that the longer shield that was included loose for the reverse lockout solenoid could NOT be put on without removing short shield which could not be removed without taking off the brake lines that I had just installed. Half sheet of paper with 2 or 3 sentences is all you would need to include.

Works fine, But there are many times that a bypass or lockout is needed.

The coupler itself met expectations and is functioning perfectly. However, there are three things I would like to report that would make the installation easier. First, some written instructions would be helpful. There was NO documentation that came with this major item. Next, I was unable to attach the solenoid cutoff for the coupler and determined the solenoid was a different thread size than the coupler's reservoir fitting. I spent extra time and two trips to the hardware store to correct this only to discover that the fitting on the reservoir needed to be removed AND REPLACED with the solenoid connection. The last item relates to the protective cover for the solenoid. A separate part is included that protects the solenoid and its fitting but nothing tells you that this needs to be installed in place of the shorter cover supplied on the coupler. One additional point is the lack of instructions to properly bleed the braking system. It is a little tricky on this item and knowing the correct process would have been helpful instead of relying on internet searches to find help.

The coupler itself met expectations and is functioning perfectly. However, there are three things I would like to report that would make the installation easier. First, some written instructions would be helpful. I started to replace the nut that goes to the backup actuator. I recall a review and looked at the video. No nut replacement, just screw in the actuator. The nut is just used for shipping. The product is excellent and my identical Titan lasted over 10 years of salt water use. Glad to see that the quality has not decreased. Will buy again from etrailer.

Ask the Experts about this Titan Brake Actuator

  • Master Cylinder to Convert Titan Surge-o-Matic Model 6 Actuator to Disc Brake Operation
    You are correct that disc brakes require an actuator with higher psi pressure than what is required by drum brakes. Drum brakes need pressure of 1000-psi but discs need 1500 to 1600-psi. You can convert your Titan Surge-O-Matic Model 6 actuator to disc brake operation by replacing the master cylinder with part # T1777405. This kit includes the master cylinder, mounting plate, hex bolt, push rod assembly and installation hardware. If your brakes locked up this should not be due to the...

  • Can Titan Model 6 Surge Brake Actuator Replace GDC Model 80
    The Titan Surge Trailer Actuator part # T4747220 will pretty easily install in place of what you have now but looking at the picture of what you have and what looks like an equal distance between the mounting holes it would seem most likely that you would have to drill at least one new hole to install the # T4747220 that you referenced. Or you could have it welded.

    The bolt hole dimensions of the Demco Brake Actuator # DM8669112 are 12-1/2 inches on center and 3 inches on center. I've attached a photo to assist. The Titan # T4747220 has mounting holes that are 3 inch on center so 2 of the 3 holes will align with your current coupler. Instead of changing out your entire coupler, you may want to simply change out your master cylinder on your Demco Actuator using the Replacement Master Cylinder for Demco Actuators - Disc Brakes # 5672.

    Info on your coupler is harder to find but it looks like your coupler is a 8,000 lb rated surge brake actuator. Which for that we have the Titan kit part # T4747220 that is a disc brake actuator designed for disc brake use. Or we have the part # T4079200 which is similar but for drum brakes.

  • Troubleshooting a Trailer with a Titan # T4747220 Brake Actuator
    I spoke with my contact at Titan about the issue you are having with the Titan Zinc-Plated Brake Actuator w/ Electric Lockout - Disc - 2-5/16 inch Ball - 8,000 lbs, part # T4747220, on your trailer. He informed me that there is no pressure adjustment on the trailer actuator, and that the breaking intensity is completely proportional to the braking intensity of the towing vehicle. He said most likely that the brake system needed to be bled again. There is a way to test the brake system....

  • How Many Bolts Needed to Mount Titan 8K Surge Coupler T4747220
    The Titan 8K Surge Coupler # T4747220 should be installed using all 3 of the smaller mounting holes or both of the larger holes (using hardware with dimensions that match) to secure it to the trailer's 3-inch-wide tongue.

  • Recommended Brake Actuator With Lock Out for 7000 LBS. Boat Trailer
    The standard tongue weight on a trailer is approximately 10-15 percent of the GTW. On a boat trailer it generally stays at 10 percent because most of the weight of a boat is towards the back end of the trailer, reducing the need for more tongue weight. This is why all of our couplers have a tongue weight of 10 percent of the GTW. If you'd like to be more definite in your tongue weight, you can always use a scale like the Sherline Trailer Tongue Weight Scale # 5780. The Titan Zinc-Plated...

  • Can An Electric Reverse Lockout Solenoid Be Submerged?
    An electric reverse lockout solenoid like found on the Titan Zinc-Plated Brake Actuator w/ Electric Lockout # T4747220 should not be submerged while connected to your 7-way. Electricity and water are not a good combination, so keeping your reverse lockout solenoid connected at the point of submersion is not a good idea as it could short out your entire trailer connection on your vehicle. What we recommend is backing your trailer up to that point with the connection, but stopping to...

  • Troubleshooting Titan Zinc-Plated Brake Actuator # T4747220 That Wont Compress
    Thank you for your recent purchases. My first thought is that there may be a short in your trailer wiring for the reverse lockout circuit. If there were a short somewhere on the trailer power could be reaching the reverse lockout solenoid when it is not supposed to. This could happen if the trailer's 12V auxiliary power circuit were shorted to the frame. You can try disconnecting the wiring for the reverse lockout solenoid to see if the coupler will engage (compress) when you back up. Other...

  • Hardware Needed to Install Titan Zinc-Plated Surge Brake Actuator # T4747220
    Thanks again for your purchase. We really appreciate your business. As for mounting the Zinc-Plated Surge Brake Actuator, # T4747220, Titan recommends using at least Grade 5 hardware and lock nuts. You can just use the 2 holes for a 5/8 inch bolt or for added strength you can also use the remaining 3 holes for a 1/2 inch bolt as well. A 4 inch long bolt should be sufficient but you will want to make sure that there are at least 2 or 3 threads on the outside of the lock nut once you have...

The Titan Brake Actuator # T4747220 is rated to 8,000 pounds and has electric lockout. The Titan # T4750820 is much the same, but it is rated up to 12,500 pounds if more capacity is needed. Both of these options are also rate for use with disc brakes. If you needed an actuator for drum brakes, the Titan # T4079200 will be rated to 8,000 pounds and the...

  • Replacement Trailer Coupler For Replacing Titan Model 6 Surge Brake With Electric Over Hydraulic
    For replacing your Titan Model 6 # T4747220 I recommend the Demco Channel Tongue Trailer Coupler # DM15931-95. They will share the same 3" and 2" bolt bolt hole separation that you are currently using on your trailer. You will need a etrailer Coupler Lock # e98888 if you wish to lock this coupler as it requires a 3" minimum span.

I only ask because there is not a model 0100, but there is a Model 10 such as part # T2477600.

  • Is an Electric Reverse Lock Out Required for Backing Up a Trailer with Surge Brakes
    There are 3 ways to allow a trailer with surge brakes to back up. There can be an electric reverse lockout, a manual lockout, or you can use free-backing brake assemblies if the brakes are drums. The easiest and most-preferred method is the electric reverse lockout like what comes on the Titan Model 6 part # T4747220. Or for just the lockout you would want the part # T4748800. I also attached a link to a page that has all of the free backing brakes we offer.

  • Parts Needed to Add Disc Brakes to Drum Brake Trailer
    If you have Atwood surge coupler # 83010 and you want to convert the trailer from drum brakes to disc brakes on one axle you will need to either replace the coupler or replace the master cylinder inside it with one that delivers the higher psi pressure required by disc brakes. Disc brakes need psi pressure in the 1500-1600-psi range so a new 8K-rated actuator/coupler like # T4747220 is needed. If the trailer has two 3500-lb axles (which would be expected if it has the 8K-rated Atwood...

  • Replacement Surge Brake Actuator for Titan Aero 6000 for Disc Brakes
    A Titan Aero 7500 will fit in place of your Titan Aero 6000 but the only one available for disc brakes is the Swing-Away Actuator w/ Electric Lockout # T4839100. This fits a 3" x 5" channel tongue but can fit a 3" x 4" or 3" x 3" with adapter spacers kit # T4842100 or # T4842100 accordingly. If you are looking for more of a traditional actuator then you can use either the 7.5K # 099-175-20 (with 3" distance between bolt holes) or the 8K # T4747220 (with a few different bolt holes).

This actuator bolts on to 3" wide channel tongues and fits 2-5/16" hitch balls. This actuator is designed to work with disc brakes and will work on trailers with up to 8000-lbs capacities.
