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

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

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. 446665

I placed an order over the phone and the sales person was quick and knowledgeable. My order shipped the next day via usps and i received it just three days later, which is fast by Hawaiian time. They sent me an e mail confirming my order and when it shipped. I? will order from them again. 502159

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

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.

  • 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 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...

  • Installation of Electric Lockout Solenoid for Brake Actuating Coupler
    For surge brake actuators, the solenoid like the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 will allow you to bypass your brake actuator when backing up. The unit screws into the back of your master cylinder and then the brake line connects to the other end. One wire of this electric lockout solenoid will connect to the trailer frame as a ground and the other will connect to the reverse light function wire coming from your vehicle. You can connect...

  • 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 #...

    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...

    The Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts part # T4748800 along with the Solenoid Shield for Titan Model 10 and Model 20 Trailer Brake Actuators part # T4836100183 will be needed in order to reverse your trailer while coupled to the tow vehicle. However, this would not have anything to do with the brake bleeding procedure. I have attached this for you below.

  • 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...

  • 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...

  • 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...

  • Recommended Electric Lockout Solenoid for Surge Brake Actuator
    For the backup solenoid for your surge brake actuator, I recommend the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800. This will fit in line with your master cylinder and brake line and give you two wires, one that will ground to your trailer frame and one that will run to the reverse light power function of your trailer connector. I've attached a video to assist.

  • Replacement Master Cylinder and Reverse Lock Out Solenoid, Titan Model 10 Trailer Brake Actuators
    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...

  • 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.

  • Troubleshooting Reverse Lockout Solenoid on 2001 Stratos Boat Trailer with Surge Brake Actuator
    Since you have voltage going to the electric reverse lockout solenoid, I'd check that solenoid's ground wire connection. If that connection is good, then you will need to replace the solenoid with # T4748800. If that ground connection is not good, you will need to clean it and possibly relocate it. You need to make sure the ground is a bare metal to metal connection free of debris, corrosion, or rust. Once you have a clean connection, I recommend putting either paint on it to protect...

  • Using Front Hitch To Move Trailer With Hydraulic Surge Brakes
    If you have a manual lockout, you will be able to use that and navigate with your front hitch without any wiring. If you have an electric lockout, you will need to supply 12 volts to that solenoid to release the brakes. I'd suggest getting a matching connector for your trailer like # PK11893 or # HM47900 and hardwiring the reverse wire directly to your battery and run a ground wire to the negative battery terminal from the connector. This will allow you to have that single function to...

  • 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...

  • Installed New Brake Solenoid on Trailer and Now Fuse Keeps Blowing When Trying to Use Brakes
    Sounds like you have a short somewhere in the system. Recheck where you wired the solenoid, # T4748800, to make sure that wiring is not frayed and touching any area of your trailer. Make sure that the ground has a good connection. Is you spliced in to the existing wires during install, check this wiring for any damage and bad grounds. All grounds should be connected to bare metal on the trailer frame. Any rust, dirt, or grease will corrupt the connection and cause issue with the unit.

  • Will the Titan Reverse Solenoid Valve # T4748800 Thread Into Titan Master Cylinder # T4747100
    The Titan Solenoid Valve for Reverse Lockout, part # T4748800 has 1/8 inch NPT male threads on the inlet connection. This will thread into the Titan Master Cylinder for Titan Actuators - Disc Brakes, part # T4747100. Both of these parts are designed for disc brake applications.

  • 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.

  • How to Wire Titan # T4748800 Reverse Lock-Out Solenoid Valve
    The Titan Replacement Reverse Lockout Solenoid you mentioned is extremely easy to wire. The solenoid has two wires exiting it. One wire grounds to the trailer tongue, the other would connect to the reverse light circuit on the tow vehicle. Once wired, the solenoid will close when the tow vehicle is shifted into reverse, preventing the trailer brakes from applying when the trailer is backed. Since it sounds like both your vehicle and trailer have a 4-pole connector, you'll need to install...

  • Will Titan Model 6 Actuator Work with a Reverse Lockout Solenoid After Orifice Fitting is Removed
    Yes, I spoke with my contact at Titan and after you remove the small orifice fitting part # T1209800 from your Titan model 6 actuator you would be able to install the Lockout Solenoid part # T4748800 and your brakes will activate correctly.

  • Where Should the Ground be for the Replacement Reverse Lockout Solenoid Valve, # T4748800
    On the Replacement Solenoid Valve, # T4748800, the best place to ground the unit is to the trailer frame at a place that is free of dirt and corrosion and where there is no paint. It is possible that you can ground it with the main trailer connector ground. The other wire attaches to the trailer connector reverse light circuit and will be activated when the vehicle is placed in reverse.

  • 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...

  • How to Wire an Electric Reverse Lockout on a Trailer to Work with a Vehicle that has a 4-Way Flat
    Since you have a 4-Way flat trailer connector, you will need to add a 5-Way flat adapter, # 20036, to the vehicle and a 5-Way flat, # HM47910, on the trailer if you want the electric reverse lockout to work. On the vehicle side, the extra wire will connect to a reverse light wire. On the trailer side, the extra wire will attach to one of the wires on the solenoid. The other solenoid wire will need to be grounded to the trailer frame. I have included a link to a video showing a typical...

  • Is a Reverse Electric Lockout Needed on a Boat Trailer with Titan Model 60 Actuator
    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. There are 2 kinds of lock outs to prevent this, a manual which is built into an actuator and prevents the coupler from pushing in, and there is the electric type. It will energize when the vehicle is...

  • 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...
