Video Transcript for Titan Brake Actuators with Reverse Lockout Replacement Solenoid Valve Installation

Today, we're going to take a look at the Titan replacement solenoid valve for Titan brake actuators with reverse lockouts. Part number is T4748800. Now, between our actuator and the line that provides fluid to our calipers, we're doing an electric lockout. Basically, this is going to be connected to ground on one side, we'll show you how to do that, and to your reverse wire coming from your seven-pole or five-pole, six-pole, whatever you've got. On the other side, it's going to act as a solenoid. As your vehicles backing up, it's going to cut off that pressure, or that brake fluid from locking up the brakes.

Basically, this is important when you're backing up a hill and you want to be able to have your trailer wheels turn freely. This prevents that pressure from being sent back. Otherwise, when you started to back up a Hill, as the actuator gets compressed, it's going to apply the brakes. It's going to make it difficult to back up.Now, the solenoid is designed to replace the thread adapter that we have here on the back of the actuators. We're going to use a half inch wrench, and we're going to get that removed.

Basically, the actuator is designed to work with or without an electric lockout. By taking this out, we'll be able to thread this in. That way it'll be set up for that lockout procedure when we hit reverse. We want to get that secured to our actuator. Going to use that big nut there.

It's a 15/16 inch wrench.Now, we'll take the flexible brake line hose. You'll have a shorter one from your kit. Remember, we've lengthened ours a little bit just to make up for the length of the tongue. We're going to get that secured down. Now, as you start it, also hold this one with a wrench, that way we don't have to worry about this turning on us.

For this, you want to use a 9/16 and then for this, we're going to stay with a 3/8. Now, for the wiring side, I'm going to extend one of the wires slightly. It really doesn't matter which one. I'm going to use a piece of 16 gauge wire. This is going to allow us to get it to the reverse signal on the plug coming from our truck. To connect the two together, I'm going to use a heat shrink butt connector. Part number is DW05744. If you don't have wire, that part number is 16-1-1. Get that crimped down.Now, we're going to use a heat source to get this shrank. You can use a heat gun, you can use a mini torch or just a lighter. The key is not to overheat it. Just want to give it some gentle heat. You can see it start to shrink down just like that. Now, once it's fully shrank, you notice the wire looks like it's much bigger, and then there's just a little clear gel that comes out of the end. Now, the other wire will act as our ground, so we're going to strip that back. I always like to twist the wires, give it something good to hold on to. Then we're going to place on a ring terminal. Going to crimp that down and we just have to attach this to the tongue, so when we hit reverse, the signal comes through here. The solenoid is going to close, not allowing the fluid to pass by. Then because we've got it grounded out, it's going to work for us.I'm going to place that right here, so it still will be accessible, but as we slide this back, most of that wiring will go inside there. We use a number 12 self-tapping screw to make that connection, just like that. Got our connections made. Now it's just slide the actuator back and get our bolts put in. With those through, we're going to place a couple of nylon lock nuts on the other side. It seems like the four-inch bolts really work out well and give us just enough bolt link there to get those nylon threads engaged, get everything nice and secure. Now, with half-inch bolts, you'll use a 3/4 inch or a 19 millimeter wrench and socket. They're the same size. Now, we'll get our bolts torqued down and that's going to complete our look at the replacement solenoid valve for the Titan brake actuators with the reverse lockout, part number T4748800.

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

What a great service etrailer provides. i recently had to place two orders for spare parts. Two different parts suppliers. I placed both orders on a Sunday. etrailer received my order and I had it by Wednesday and had the part installed by Wednesday night. They kept me informed through the whole process via email. My second parts order through a different company had to be canceled and reordered 3 times in 3 days, still don't know where my parts order is. etrailer sets the expectations that others should follow. Great Job. 807740

So far so good. The customer service was excellent. They helped me through the process of product selection with ease and a sense of humor. Much better than the local shops here in Anchorage. I'm not mechanical in any sense so I found the online installation videos to extremely easy to follow. I ended up replacing all the brake lines, the master cylinder and the actuator. It was easy but I did it with help of the videos and a few phone calls to customer service who talked me off the ledge. The calipers will be replaced this year and I'm hoping for similar results. I'll keep you posted and thanks again. Great products, CS and online help. 793307

  • Troubleshooting Reverse Lockout Solenoid Replacement on 2006 Mastercraft Trailer
    Thanks for the explanation. The Solenoid Valve Replacement Kit for Titan/UFP Brake Actuators with Reverse Lockouts # TK71-755-00 is what you can use for that style coupler. It simply has another connection for a drain to give you the bypass. Since your current one has this, you can simply remove the wiring and leave it in place with the Titan # T4748800 you have behind it. Simply connect the wires to that unit and you should be good to go. If you prefer to remove the old one you can...

  • Troubleshooting UFP Surge Brake Coupler Operation
    The electric lockout doesn't do anything to the actuator itself, it is a solenoid that doesn't let the fluid pressurize to case the wheel cylinder or brake caliper to engage. The coupler not returning to the forward location has more to do with the Replacement Shock Absorber Spring Kit for Titan/UFP Brake Actuators # TK71-758-00. If you want to use the manual key, it won't be an issue.

  • Troubleshooting Titian Actuator with Electric Lockout Not Working When Backing up Driveway
    If your electric lockout solenoid on your Titan actuator isn't engaging when you are backing up your driveway then either the wiring is broken so it isn't receiving the signal or the solenoid has gone bad and it needs replacing. Check the wiring and if it looks good then the solenoid itself it likely the culprit and you would need part # T4748800 for Titan Model 6, Model 60, Aero 7500, and newer Model 10 and Model 20 actuators. If you have a 2000 or older Model 10 actuator, the adapter...

  • Troubleshooting Boat Trailer Brakes Locking Up in Reverse
    It sounds like your reverse lockout solenoid is not working properly. You can use the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 or the slightly better designed Demco # DM5837. You will wire one side of the solenoid to the reverse light function on your 7-way and then the other wire will be grounded to your trailer frame. I've attached a couple videos of installations to assist. I've attached a photo of the 7-way pin locations to assist.

  • Adding Electric Lockout and 5-Way to Trailer with Titan Model 60 Actuator
    To add an electric lockout to your Titan Model 60 actuator only requires the part # T4748800 and then if you wanted to add a shroud to protect the lock out you'd also need the part # T4835800183. To activate the electric lock out you need a reverse light circuit carried to it. Typically a 5-way is needed for this to carry the extra circuit. For a 5-way you'd then want the part # W002290 which you can replace your 4-way with. For a 7-way to a 5-way adapter then you'd want the part #...

    I spoke with my contact at Titan and he informed me that this Replacement Solenoid Valve # T4748800 could be used in the brake line instead of on the back of the master cylinder like it typically installs. He said as long as you securely install it on the brake line it would function properly. This is the correct unit for the model 20 actuators. He also said that the male side of this product has 1/8 inch pipe threads, and the female side has 3/8-24 inverted seat threads that 3/16 inch...

  • Replacement Reverse Lockout Solenoid for Titan Model 10 Brake Actuating Trailer Coupler
    I believe you meant Titan Model 10, is that correct? If so, the Titan # T4748800 Replacement Solenoid Valve you've looked at would be compatible with your coupler. 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...

  • 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.

  • Does Trailer Surge Brake Solenoid for Reverse Lights Draw Enough To Overdraw Reverse Light Circuit
    I understand your concern, but we've yet to see a reverse lock out solenoid overdraw a reverse light circuit and we see this type of setup pretty frequently. For example, the Titan reverse lock out solenoid part # T4748800 only draws 8 watts so it doesn't really draw much.

  • Surge Brake Actuating Coupler With Reverse Lockout Boat Launching
    With your Titan surge brake actuating coupler with electric lockout # T4748800, I recommend unplugging the wiring before launch. The issue with most is how long before launch does it need to be unplugged. Obviously there is some maneuvering prior to launch that it is helpful to have brakes deactivated for so I recommend disconnecting the wiring just before you put the trailer axle into the water. This will keep all of your electrical safe from any water and electricity issues and will...

  • Changing a Titan Model 60 Drum Brake Actuator to Disc Brakes
    The Titan disc brake master cylinder orifice is # T4750300. Or you could change out the master cylinder on your Titan model 60 actuator with the disc brake version, # T4820000, and get all new parts. It fits right in place of the original. A lockout solenoid such as # T4748800 will work with the disc brake orifice.

  • Troubleshooting Brakes Locking Up When Backing on New Tandem Axle Trailer
    It sounds like your new tandem axle trailer has a surge brake coupler. You will need to use the manual lockout on the coupler if there is one or add a Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800. This electric lockout connects to a 5-way trailer plug like # HM47890, and an adapter like the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036 will connect to the reverse light circuit at your tail light to send a signal to that solenoid to...

  • Troubleshooting Titan Surge Disc Brake Actuator
    It could be that your reverse lockout solenoid needs replacement. Part # T4748800 is the replacement part. But I suspect your master cylinder is the cause for the brakes staying locked up until you release the pressure from the bleed valve on one of the calipers. You can check your master cylinder to see if the piston returns to its normal position after you manually compress it. If not you will want to replace it with part # T4747100 which fits the model 10 disc actuator. For the same...

  • Signs that Solenoid Valve for Titan Brake Actuator with Reverse Lockout #T4748800 Needs Replacement
    I spoke with my contact over at Titan and while they couldn't provide the actual ohm reading you'd get when testing the Replacement Solenoid Valve # T4748800, he did give some information that may be helpful. You'll need another person to help you verify this first one, but when you put the vehicle in reverse you should be hearing a distinct snapping noise. If you don't hear a snap when trying to back up, the solenoid is bad and will need replacing. He also mentioned that this solenoid...

  • 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. A normally closed system...

    As far as a master cylinder, you will need the Master Cylinder for Titan Actuators, # T4747100, which is designed for Model 10 or 20 Titan actuators and is designed for 1-1/4 inch bore disc brakes. For a reverse lock out solenoid, you will need the Solenoid Valve with Fittings for Reverse Lockout - Normally Open, # T4748800. This solenoid comes with the necessary fittings and installs in-line with the system. Finally, to protect the solenoid, you will need Replacement Back Up Valve...

  • Adding Reverse Lockout to Trailer with Titan Model 60 Actuator
    I really wish there was a cheap and easy way to lock out a Titan model 60 actuator but the only way would be with an electric lock out like the part # T4748800. This threads onto the back of your current actuator and once ran to the reverse light circuit it will allow your trailer to backup without locking up the brakes. You will need to replace your current 4-way with a 5-way like part # HM47910. And then to convert the 4-way on your tow vehicle you'd need the adapter part # 20036...

  • Is the Titan Reverse Lockout Solenoid Compatible with Non-Metallic Master Cylinders?
    The Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 is compatible with a variety of master cylinders just like the Demco Reverse Lockout # DM11993. Either will work with a plastic master cylinder like the Demco # 5650. I recommend going with the Demco Solenoid because it is made to be a non-bypass solenoid so it seems to function a little better.

  • 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.

  • Does Titan Trailer Coupler, # T4819900, Need A Solenoid Valve When Trailer Is In Reverse
    On the Titan Trailer Coupler, # T4819900, you need to add a separate solenoid to disable the brakes when traveling in reverse. You will want to 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. The difference is the normally open lets the brake fluid still circulate through the brake lines, where as the normally closed valve would...

  • How to Back Up Trailer with Surge Brake Model 60 Actuator Installed
    The issue is that with the way a surge coupler works when backing up, normally up hill, the trailer is pushing the other way which will cause the actuator to compress in sending fluid back to engage the brakes. This makes it very difficult or impossible sometimes to back the trailer up. Your Titan Model 60 actuator would need to have a lockout solenoid installed on it so that it could back up. For that you'd need the Titan solenoid part # T4748800 and you'd be able to back the traler...

  • Brakes Lock Up in Reverse But Will Not Work While Moving Forward with Titan Model 10 Brake Actuator
    I spoke with my contact at Dexter who owns Titan and they informed me that there could be a few different issues. If they are drum brakes and they were just installed then most likely they are installed on the wrong side of the trailer as this is the most common issue with this problem. The reverse solenoid part # T4748800 could also be installed backwards as this would then shut off the flow of fluid while going forward but not backward. If the actuator still does not work once you...

  • If Solenoid is Not Connected Will Brake Actuator Work?
    If the Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 is not connected, the brake actuator will still work; however, the trailer brakes will lock up when you go in reverse. So you will need the solenoid in order to keep them from locking when you back up.

  • Installation of Electric Reverse Lockout Solenoid for Surge Brakes
    If you don't install the reverse lockout solenoid # T4748800 that came with your actuator, then unless you have free backing brake assemblies, you will not be able to back up without activating the brakes immediately. This solenoid basically works like a valve not allowing the hydraulic brake fluid to move through the brake lines to activate your brake assemblies. Because you have a 4-way, I recommend you add the Hopkins Endurance 5-Way Flat Trailer Wiring Kit - Vehicle and Trailer...
