Video Transcript for Titan Accessories and Parts T4748800 Review

Today we're going to take a look at the Titan Replacement Solenoid Valve for Titan Brake Acuaters with Reverse Lockout. Now this backup solenoid value will install at the back of your acuator into the brake line connection and wires into your tow vehicle so that the trailer brakes do not activate when you shift your tow vehicle into reverse. Now to use this feature, you must have a 5-full flat, 6-way round or 7-pole wiring harness on your vehicle. It is designed for use with the Titan model 6, the model 60, the Arrow model 7500 and newer model 10 and model 20 acuators. On the 2000 and older model 10 actuators, an adapter might be needed and we do sell that separately because the threads are different. It's part number T4750200 and it is listed on our website as a related product. Now this solenoid will also fit the Dico model 10, 20 and 60 acuators. The pressure rating on this is 800 psi.

The orifice size inside the solenoid is 1/32nds of an inch. I'll give you a few sizes on the wrenches you might want to use when you connect this to the actuator. The large size uses a 15/16ths or 24 millimeter size wrench. When you connect your brake line to the smaller size brass fitting, it's either 9/16ths or 14 millimeter size wrench. Now the silenoid does, as you notice, have two wires. They will need to be connected.

One will be grounded. The other will connect to the reverse light circuit. They're both black wire so either wire will work for either function. What I want to show you here is we happen to have a model 60 acuator to show you the back of it. That's how it will come when it doesn't have the solenoid valve. What you want to do, this is where your brake line will connect.

We'll go ahead and pull that plug out. Then what you want to do is remove the nipple that's already in there. Use a 12 millimeter wrench and you can just unscrew the complete nipple out of the back of it. Then you'll take your solenoid and take this in and put it right in there. Then just tighten that up.

Then, using a wrench on the large size, like I said either 15/16th or 24 millimeter, just tighten that up. Then run your brake line right into here and the wrench for this size, again, is the 9/16ths or 14 millimeter. That's how you would install it. Then you have your two wires that you just have to connect. Now one other thing I would also recommend to purchase . You can see there's a cover right here, but because you have added the silenoid, it's sticking out, you don't want anybody stepping on it or breaking it off. What I would recommend is to remove this part and then purchase this extra piece. This is the solenoid cover. It's designed to protect this. You would remove this one, bolt this in its place and you can see, with that, it will protect anything from damaging that solenoid. I'll go ahead and remove it. That should do it for the review on the Titan Replacement Solenoid valve for Titan Acuators with reverse Lockouts.

This review is not intended to persuade you to buy or not buy this solenoid. If you need one, you have to have it. But I will caution you based on my experience to be careful with it. The device has 1" wrench flats to secure it, but only an 1/8" pipe threaded nipple that is unreinforced, soft brass going into the master cylinder. My coupler has guide pins out the rear that prevent a 1" wrench from fitting around the solenoid properly. So I tried to tighten the thing at an angle and of course accomplished little other than to prove how fragile the thing is and break it right off. I'm not impressed with the design, but that's how they made it. My solution is to extend a short pipe out of the master cylinder to clear the pins and be much more careful assembling it next time. It isn't for heavy hands. 12856


Comments

I couldnt agree more. The 18 nipple is practically designed to fail. The first broke upon installation so I had to immediately order a replacement. The 2nd one survived for close to a year but just snapped off at the same point. There also appears to be slight corrosion where it broke off. I have the weather protector cover which seems to imply the solinoid itself isnt weather-rated but it is ineffective against road spray or stormy weather. Unfortunately, the solenoid is a required part for my installation but Id sure avoid this part if I could. I just ordered my 3rd one.

Fit perfectly and works great. Type of delivery method needs to be more clear. UPS w/USPS is different from UPS. We had to fight with the post office to get because we have no mail delivery at our house but we do get UPS FEDEX. The Post Office said they should be sending it back because we are not allowed to intercept mail. But we talked them into giving it to us, Thank heavens for the tracking number. 152194


Comments

The valve is working just fine. But we still have problems with shippers sending our purchase with the upsusps final delivery method since we have no mail delivery. But we do have direct ups delivery or Fedex delivery. You should differentiate these in the shipping choices. We will order things again.

Products were great. I have one suggestion to the shipping dept. at trailer: DON'T put small items in the same craft paper that is used to fill voids in the shipping box. When I opened my box I pulled out the big bunch of craft paper and set it aside to pitch. I pulled out the bigger brake parts and then realized that i was missing two smaller items. At first I thought maybe they were back ordered. I checked the shipping paper and they were to be in this box. After going thru the craft paper I was going to pitch I found them inside. Close Call!!! Put the small items in a small box or envelope. Thanks. 309406

I bought 2 of these and they did not last a year. not sure why , but after some time they close shut and disable your brakes on the trailer (with no power to it). I am assuming that the brake fluid destroy the moving parts inside, all though it is very funny as the solenoid should be "Fail Open", meaning that it should remain open when no electricity is applied or it breaks. I'm looking for some sort of a manual replacement that I can close only for backing up manually. Very disappointed. 239362

The item I ordered and paid for was not in stock. I was given notice a few days after ordering that they did not have in stock and shipping would be delayed a few weeks. When the item did arrive, it was not the one that was in the picture when I ordered it. The one I ordered was blue, this one was black. Same specs, just a different item than pictured. The best part of the experience was that I was kept informed with several emails as to the whereabouts my order stood the whole time. 228466

I have purchased items previously from E trailer and all have worked well. This was the exception. It lasted less than 1 year. used trailer at the most 6 times. The solenoid "clicks" as it should but doesn't stop the fluid. the brakes lock up when backing. I called E trailer to check on the warranty. He informed me that it was for only 30 days and asked me if I would like to purchase another. I declined. I'll have to get a better one from somewhere else. Disappointed. 321908

This was the only item that I bought from you that didn't meet expectations. I was in the process of installing it by hand onto the master cylinder when the front brass fitting broke off. I never even got to tighten it by wrench. I don't know if it was cracked from the start or just poor quality brass, in wither case, it was unusable. The master cylinder and cover are just fine and work perfectly. 134646

eTrailer delivered the correct part, on time and at a good price. The solenoid valve itself has a small 1/8" NPT male thread with large 7/8"(?) wrench flats. Be careful tightening... Also, the solenoid wires are both black. It doesn't matter which one is ground and which is powered. (It took me a few minutes to figure that out.) 146925

The support was great. The only issue I had was more towards the manufacturer of my trailer. This valve was listed as a replacement for the original that came with the trailer, when in fact, the original orifice was 1/4 inch and this one has one is 1/32. I was assured by Master Trailer Mfg. that it would work without issues. 186407

  • How to Activate Boat Trailer Surge Brake Lockout from the Factory 7-Way on a 2012 Toyota Tacoma
  • It sounds like you have a factory 7-Way connector on your 2012 Toyota Tacoma and that you also have the dealer supplied electric brake controller wiring harness for wiring an electric brake controller in the cab of your vehicle. Since your boat trailer is equipped with surge brakes, you will not need to install an electric brake controller in the cab of your Tacoma. The first thing you should do is check the center pole, see photo, in the 7-Way connector on your vehicle with a circuit...

  • Installing a Surge Brake Actuator on a Truck Bed Trailer Axle with Factory Drum Brakes
  • Yes, you can use a hydraulic surge brake actuator on a 3/4 ton pickup bed with factory hydraulic drum brakes. I produced a short video showing the actuator I recommend and explaining the application. You would want to use a drum brake actuator for OEM drum brakes. You will also need an electric lockout solenoid to lockout the brakes when backing because automotive brakes will apply in reverse. I recommend the Titan Zinc-Plated Brake Actuator, # T4339720, for drum brakes which includes...

Couplers are available with either electric or manual lockout, or no lockout. This particular Titan coupler does not offer this function.

  • Parts Needed to Backup Without Putting on the Surge Brakes When Parking or Launching a Boat Trailer
  • Yes, there is a way to back up your boat trailer and keep the surge brake actuator, # T4332900, from applying pressure to the trailer brakes. You will need an electric lockout solenoid, # T4748800, which will close when you shift the vehicle into reverse, allowing the trailer to be backed. Along with the solenoid, you will need a solenoid cover, # T4835800183, if your actuator is the model 60 actuator that you referenced.

  • Normally Open Reverse Lockout Solenoid for Disc Trailer Brakes
  • The normally open style like # T4748800, will only prevent fluid from going back to trailer brakes when you put the vehicle in reverse. Once the vehicle is in reverse, the normally open solenoid will close and allow you to back up without the brakes engaging. On a normally open system, you will need to be careful when backing up because if you hit a curb or another object it could add even more pressure to the master cylinder and could possibly damage it.

  • Hydraulic Trailer Coupler is Locking Trailer Brakes When Trailer is in Reverse
  • Without any background information, it will be hard to say what you have going on. Have you recently replaced the coupler or master cylinder? Did the brakes previously function correctly, but are recently locking up when the vehicle is placed in reverse? Given the information available, my best guess is that either your reverse lock-out solenoid is faulty, one of its wires has become disconnected, or the signal from the reverse light circuit on the vehicle is not reaching the solenoid...

  • How Does a Reverse Lockout for Surge Brakes Wire to a Trailer
  • The wiring of the Replacement Solenoid Valve # T4748800 is ran to the reverse light circuit of the trailer's wiring connector. Basically one wire will get run to the reverse light circuit and the other wire will get grounded on the trailer frame. Doesn't matter which wire. If your trailer only has a 4-way you will need a # 20036 to convert it to a 5-way so that you can tap into your vehicle's reverse light circuit. Check out the video I attached to the right for more info.

  • Troubleshooting Trailer Surge Brake Tongue Slamming Forward and Back
  • It sounds like the shock in your surge brake actuator is in need of being replaced. The shock will act as a dampener to allow the coupler to return slowly and apply the brakes in a controlled manner. The loud banging noise you are hearing also supports this. In order to replace the shock we first need to know what coupler you have. If you can email me back with pictures and any model names or numbers you can find I'll help you track down the correct shock. For example, if you had a Titan...

The Demco # 40715 and 40716 you referenced would be an acceptable replacement. In my experience, there is not perceptible difference in quality between Demco and Dexter brake assemblies.

  • Does the Titan Model 60 Trailer Brake Actuator have a Reverse Solenoid with Brake Fluid Return Line
  • The actuator that you have referenced, # T47154007K, does not have a reverse lockout. However, if you were to add one using # T4748800, it works by blocking the flow of fluid back to the brakes when the tow vehicle is placed in reverse. There is no return line for the fluid. The master cylinder in this actuator is # T4820000.

The solenoid would mount between the master cylinder outlet at the rear of your actuating coupler between the outlet and the brake line. The solenoid has two wire leads. One wire would ground to the trailer, the other would connect to the center pin of the trailer connector. Keep in mind, that the center pin of the connector...

  • Does Titan Trailer Coupler, # T4715400, Need A Solenoid Valve When Trailer Is In Reverse
  • On the Titan Trailer Coupler, # T4715400, you need to add a separate solenoid to disable the brakes when using reverse. You will use the Titan Solenoid Valve with Fittings for Reverse Lockout, # T4748800, which is a normally open valve. It is internally grounded so you just have the one wire to attach to the reverse light circuit. You will also need the Titan Solenoid Valve Cover, # T4835800183, that will attach to the actuator and protect the solenoid from the weather. The difference...

  • Brakes Lock Up After Installing Reverse Lockout Solenoid Valve # T4748800
  • I would recommend bleeding your brakes after installing a new Solenoid Valve, # T4748800. The main brake line must be disconnected from the actuator to install this item and anytime the brake lines are disconnected, there is a chance for air or some type of debris to enter the brake lines. The electric lockout solenoid should not cause your brakes to lock up after you come to a complete stop. The solenoid has two wires, one should be connected to the reverse light circuit coming from...

  • Electric Reverse Lockout is Not Working on a Boat Trailer
  • First, make sure that your trailer has an electric reverse lockout and that the 5th wire is connected to it and not something else. Then, on the vehicle side, check that the center pin wire is connected to a reverse light circuit behind one of the tail lights on the vehicle. You can use a circuit tester like # 3808 if needed to make sure the center pin provides power when the vehicle is put in reverse. Then plug in the adpater you have and make sure that the pin that corresponds to the...

  • Troubleshooting Trailer Reverse Lock Out Solenoid that Doesn't Work
  • If the solenoid is getting a full 12 volts and is grounding properly it should be shutting all the way. Since you said it is clicking that makes it sound like it's getting power. You could try improving the ground circuit but most likely that's not it. Is it possible the brakes are also activating while moving forward and the solenoid isn't at fault? Typically if a reverse lockout solenoid is getting power and grounding properly and it still isn't working it needs to be replaced....

  • Replacement Master Cylinder and Backup Solenoid for Titan Model 60 Trailer Brake Actuators
  • Since the fitting broke off, there could be other damage to the master cylinder, so I would recommend that if you keep your Model 60 Actuator, replace the master cylinder with # T4820000 for disc brakes or # T4395100 for drum brakes. The Replacement Solenoid Valve for Titan Brake Actuators, is # T4748800. It fits Titan Model 6, Model 60, Aero 7500, Model 10, and Model 20 actuators. I could not find any information on a Model 66.

  • Troubleshooting Trailer Ball Fit and Backing up with the Titan Model 60 for Disc Brakes # T4332900
  • The Titan Zinc-Plated Lever Lock Actuator # T4332900 that you referenced is adjustable and will fit trailer balls that are 1-7/8 inches, 2 inches, and 50 mm. In order to fit the coupler to the specific size of trailer ball that you have, some small adjustments can be made to optimize the fit. If you are using the Titan Level Lock Brake Actuator # T4332900, with different size trailer balls to tow your trailer adjustments will have to be made each time a different size trailer ball...

  • Troubleshooting Surge Brakes Locking up When in Reverse
  • With surge brakes, you have a brake actuator applying the needed pressure to the brakes but to be able to back up you will need to have a manual lockout or an electric lockout solenoid, like # T4748800, which will close when you shift the vehicle into reverse, allowing the trailer to be backed up. You may also need a solenoid cover like the Titan # T4835800183, depending on what brake actuator you currently have. Typically surge brakes are found on boat trailers, and commonly the...

  • Can an Electric Lockout be Added to Titan Trailer Disc Brake Kit, # T4843300
  • There is enough space underneath the Fold Away Coupler in the Titan Disc Brake Kit, # T4843300, to add an electric lockout, # T4748800. With the lockout installed, you will not have to use the manual lockout that comes on the coupler. If you click on the last picture for Actuator, # T4839100, you will see the space underneath.

  • Galvanized Surge Brake Actuator and Brake Assembly for a 3,500 lb Axle
  • The Titan Zinc-Plated Brake Actuator part # T4332900 would be an excellent surge actuator. This has a 6,000 lb capacity. This model does not have a lockout feature, but one could easily be added with the part # T4748800 so that your trailer could be backed-up without the brakes activating. For 10 inch brake assemblies the part # DMSB18794M would be great for the left hand side of your trailer, for the right hand side you would want the part # DMSB18793M. I also attached an FAQ article...

  • Can the Electric Reverse Lockout Solenoid be Used on a Titan Model 60 Trailer Brake Actuator
  • It sounds like your model 60 actuator is for drum brakes and it has the check valve inside the master cylinder. You can use the electric reverse lock out solenoid # T4748800 with the model 60. It will attach directly to the master cylinder and the brake line will attach to the other end. When the vehicle is in reverse, it will not allow fluid to go back to the brakes. The electrical connection needs to be made to the vehicle reverse light circuit. You will also want to protect the solenoid...

  • Availability of Trailer Disc Brake System with 7000 lb Capacity Brake Actuating Coupler
  • Since we purchase the kits directly from Titan, we are not able to make that substitution. However, Titan does offer a kit, part # T4843600 that uses the higher-capacity Aero 7500 actuator. The Aero 7500 features a manual reverse lock out, but if an electric lock-out is desired the # T4748800 can be easily added.

  • Recommend Replacement Actuator For 2 Inch Ball on My 1989 Karavan Boat Trailer
  • When determining which replacement actuator you will need, you need to determine what is the width of the trailer tongue and the weight capacity of your coupler. The item you selected, Atwood Hydraulic Brake Actuator, part # 84132, has a capacity of 6,000 lbs and fits a trailer tongue that is 3 inches wide. I did some research on the internet and was able to contact Karavan trailers. The representative at Karavan informed me that the actuators they have for their boat trailers has...
