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.

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 636937

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. 549905

Ask the Experts about this Titan Brake Actuator

  • How to Bleed Brake Lines with Titan Model 60 Hydraulic Brake Actuator Without Electric Lockout
    The Titan Brake Actuator part # T47154107K has a master cylinder with a fitting at the end. The fitting is a 3/16 inverted flare where the brake lines connect to. 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 one of the actuator. If you...

  • Replacement Coupler Needed for Tie Down Engineering 66 Model Actuator
    I was able to find that your Tie Down Engineering 66 Model actuator fits trailer tongues that are 3"x3", 3"x4", and 3"x5". It is only compatible with 2" hitch balls but I was unable to find the mounting hole measurements. We do have a wide variety of actuators like the Titan # T47154107K or standard couplers like part # DM12925. Since you say straight coupler I am not sure if you are looking for an actuator that doesn't have a drop or if you are looking for a standard coupler. If you...

    You shouldn't be experiencing issues with bleeding the brakes with a Vacuum Brake Bleeder, like part # PTW87030, after installing the Brake Actuator with Electric Lockout # T47154107K. It sounds like you might have a clog somewhere in your brake line. What you will want to do is find the next closest fitting from the brake on the trailer and try bleeding the brake line from there. If it bleeds just fine then you know that you need to replace the brake line section that you just bypassed....

  • 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 # T47154107K. 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.

  • How Do You Choose The Correct Trailer Coupler
    An actuator weight capacity should be used to match the weight capacity of the trailer it is going to be used on, and the type tongue it is to be attached to. I have attached a helpful article that explains trailer couplers and how they are typically sized. The Titan Zinc-Plated, Leverlock Brake Actuator w/ Lockout Shield, part # T47154107K, you referenced is used for a straight tongue trailer up to 7,000 lb capacity. This is a bolt-on installation and will mount on trailer tongues...

  • Brake Kit and Actuator Needed for a Tandem Axle Boat Trailer
    There are a few things we will need to know before selecting the correct brake kit and actuator for your tandem axle boat trailer. We will first need to know what type of brakes you are choosing and the gross trailer weight of your trailer before selecting an actuator. The first item to check when choosing brakes is to make sure there is a brake mounting flange attached to the axle. If it does not have a brake mounting flange, you would first need to have one welded to the axles by...

  • Recommended Surge Brake Actuator For Disc Brakes With Electric Lockout For 1993 Boat Trailer
    To make sure you choose the right disc brake assembly that will work with your trailer spindle, you will have to either measure your spindle or get the part numbers from the existing bearings and seal. Along with the axle capacity, wheel diameter and wheel bolt pattern. You may have a sticker or plate on your axle with the capacity listed. I have attached a drawing that shows where you need to measure on your spindle if you are unable to find the part numbers on the bearings or seal. If...

  • Troubleshooting Corroded Master Cylinder on Titan Actuator 60 Model
    I spoke with my contact at 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 extended...

  • Titan Trailer Disc Brakes Lock Up While Towing and Will Not Release
    It sounds like you are getting air in the system somewhere which could be from a hose with dry rot or a compression fitting especially since the trailer has not seen too much activity. To check for leaks you can fill the reservoir and manually actuate the brakes and look for leaks. Repair or replacing leaking parts, bleed the system, and see if that was the issue. It is also possible that the break away cable is partially engaged. If it is, it will need to be reset and the way you do...

  • 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 # T47154107K. This coupler...

  • Should Disc Trailer Brakes be Added to Front or Rear Axle on a Boat Trailer
    You can install disc brakes on just one axle. Install them on the rear axle which will prevent the back of the trailer from raising up if braking hard. I have included a link to the disk brake kits we have. To make sure one of these kits will fit, or to piece together a kit that will fit, I would need to know the inner and outer bearing numbers. I have included a link to a help article on adding disc brakes to a trailer that should also be helpful.

  • Disc Brake Actuator for a Trailer with a 2-1/2 Inch Wide Tongue
    You can use # T47154107K by using spacers to take up the gap between the trailer tongue and the coupler. The spacers will need to be placed on either side of the tongue and will need to have the same dimensions to ensure the coupler is installed evenly. Spacers will have to be fabricated and obtained locally.

  • Recommendation for a 6k Disc Brake Trailer Actuator with Electric Reverse Lockout
    Take a look at Titan actuator # T47154107K. It couples to either a 1-7/8", 2", or 50mm ball, has a 7,000 pound capacity, and fits a 3 inch wide tongue. It also features an electric lock out. As long as the trailer is not rated higher than 7,000 pounds, this actuator will work with 4 disc brake assemblies.

  • How Long Should Trailer Breakaway Cable be That Attaches to Vehicle Hitch
    This is a really good question that we've debated here a few times but the final word was determined to be that you want the breakaway cable to attach to the vehicle hitch/frame and should be longer than the safety chains according to RVIA Recreational Vehicle Industry Association. This will activate the brakes in the event you lose the trailer connection and the safety chains fail. Most of the ones we carry are between 4 and 6 feet long.

  • What Voltage is Needed for the Electric Reverse Lockout Solenoid on a Titan Actuator
    The reverse lockout solenoid on the Titan actuator # T47154107K is rated for 12 volts. Nine volts might do the trick but 12 volts is ideal. If you cannot get 12 volts at the reverse lights or 7-Way trailer connector then you may be able to use a fuse tap at the reverse light circuit fuse under the hood. There will be some slight movement but if the unit is banging around a lot then it could indicate worn parts.

  • How To Wire For Lockout On Titan Coupler To Vehicle With 7-Way And Trailer With 4-Flat
    To connect the electric lockout on the Titan Trailer Coupler, # T47154107K, to your truck you will need to make sure the center pole of the 7-Way connector on your vehicle is wired to the reverse light circuit. If it is not wired to the reverse light circuit you will need to splice into the reverse light circuit behind the vehicles taillights and wire to the center pole inside your 7-Way vehicle connector. Once the 7-Way connector has the reverse light circuit at the center pole...

  • Trailer Brakes Stayed Locked Up unless Trailer is Disconnected
    It sounds like you have electric trailer brakes and there is a short circuit that is causing the magnets to stay energized. When you disconnect the trailer from the tow vehicle no electricity is getting back to the magnets so the brakes release. The most common cause of this situation is a dirty or corroded trailer connector. You will want to check the vehicle and trailer side connectors and make sure they are clean and corrosion free inside and out. If the issue continues to happen...

  • Why Arent Surge Brake Actuators Adjustable
    I can probably track down some instructions for the Titan part # T47154107K 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.
