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

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

  • 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 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 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 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.

  • 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.

  • 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 #...

    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.

  • What are the Thread Sizes on the Titan Replacement Solenoid Valve
    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...

  • 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 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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.

  • 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...

  • 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 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...

  • Do Both Pigtail Leads on Reverse Lockout Solenoid Have to Be Connected
    An electric reverse lockout solenoid like # T4748800 from Titan and # DM11993 from Demco does have two pigtail leads. These leads are non-polarized, so either wire can be used as ground or hot. We are not familiar with any single-wire self-grounding solenoids similar to these units. If there is not a strong enough ground to let full reverse light signal voltage reach the solenoid, then it is possible that it could engage only partially. This would explain why the brakes could still be...

  • 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.

  • 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...

  • 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.

  • 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...

  • Recommended Reverse Lockout Solenoid for Trailer with Brake Actuating Coupler
    The Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 is a valve that stops brake fluid pressure when the solenoid is activated. It is a basic two way valve either open or closed. The wires connect to your reverse light signal and to your trailer ground to allow you to back up with a brake actuating coupler without activating the trailer brakes.

  • 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...
