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.

Great. No more getting out and putting in the reverse lock out pin. You install it behind the master cylinder, hook it to the reverse lights and Wala, the brakes don't grab.

Part purchased as part of an upgrade to disc brakes on a surge activated 4 wheel system. It works fairly well but there is definitely some resistance when reversing into my (slightly) uphill driveway.

No issues what so ever with etrailer. On time, exactly what I ordered. A side note; I installed the reverse brake solenoid check valve myself. There were no instructions, but it should be pretty easy for someone with basic mechanical skills to install. Had to make up a special cover to prevent the extended brake line tube from getting bent when stepping across the trailer hitch. Bleading the brakes can be a little tricky if a person hasn't done that before.

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.

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.


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.

This isn't necessarily a product review. It's a simple switch and it solved my problem. But I would rather comment about customer satisfaction. Website was easy to navigate but more so than that was calling the the company. Calls were promptly answered, no question was to stupid and they emailed the answer about the product information in case you didn't make decision right at that point. I have purchased a couple of items from e-trailer and have been very satisfied. If you have a trailer, or any of the many other products they offer, I think you will be happy with choosing this company. I don't usually write reviews, but this few minutes to comment doesn't compare to the time they spent with me to work out a small hiccup I had on my job. Regards, Charlie L.

I had to have the master cylinder on my boat trailer's surge brakes replaced and the service station's supplier said that he did not have the needed reverse lockout solenoid valve in stock and couldn't get one for the near future. I looked on the internet and found what was needed at etrailer. It was available and I ordered it. I received it in a few days and took it to the repair shop. The tech who installed it was pleased to get it quickly and also stated it was less than half what his supplier's price was.

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.

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.


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.

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.

I ordered this part from etrailer.com because I have ordered items from here before and I have always got what I expected. This servo arrived with other parts and functioned as expected. I would recommend etrailer as the first stop when they are looking for trailer parts. Good price, good selection, and good service.

Pat, Thank you for your review. If you are looking for an actuator with an electric reverse lock out feature built in I would recommend part # T4747220
Titan Zinc-Plated Brake Actuator w/ Electric Lockout - Disc - 2-5/16" Ball - 8,000 lbs
$403.44
. This Titan Zinc-Plated Brake Actuator allows you to reverse your trailer without activating the trailer brakes. This also comes with the built-in shield to protect the solenoid valve from outside elements.

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.



- T4748800
by:

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.

    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...

    For your master cylinder # T2374400, the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 will serve you well. The solenoid does not regulate the pressure from the specific master cylinder when the valve is not activated so drum brakes will have up to 1000 psi and disc brakes up to 1600 psi.

    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.

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.

  • 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.

    Since you have surge brakes on your trailer there are a couple recommended options for allowing it to back up. You can install free-backing brake assemblies (probably not what you would want), install a reverse solenoid like part # T4748800, or you can lock out the actuator by welding or bolting the inner and outer pieces together. I would recommend you go with the electric lockout since that will allow you to back up and still allow the trailer to stop when towing.

  • Troubleshooting Wiring for a Reverse Lockout Solenoid on an Old Boat Trailer
