Today on our boat trailer were going to be installing the Titan brake actuator solenoid valve for reverse lockout, part number T4748800. Well first remove the nipple out of the back of the brake master cylinder of our actuator. Then we can go ahead and take the new solenoid, thread it directly into the back of the master cylinder. Now for this application well need to relocate the brake line so that we can run it directly into the back of the solenoid. To do this were going to go ahead and make a mark and then drill out a hole. Now weve got our pilot hole drilled out well use a step fit process to move up to a nine-sixteenths.
Now with our first hole drilled out well move back on the frame and drill out a second hole. Once we have it to our nine-sixteenths size we can then take the cutoff wheel and cut out the section between the two holes. Now that we have our cutout made, using a socket carefully bend the line to go into the actuator, being extremely careful not to crimp the line. Once we have the line bent we can go ahead and install it into the back of the actuator and tighten it down, being careful not to over tighten it because over tightening can cause the brass fitting to break. Now that the solenoid is secure well go ahead and install the brake line.
Now with all our components installed well need to bleed the air out of the braking system. To do this well open up the bleeder on the brake caliper and remove the cap from the master cylinder, and well also make sure we have a full master cylinder. After a bit of time the air will self-bleed out of the bleeder, assisting in getting the air out of our system. After you gravity bleed it its recommended to do a vacuum assist, or manual power bleed. Once weve bled all the air out of the system were ready to hit the road.
For additional protection of our solenoid well add the Titan Solenoid shield. To install this shield well remove the four fasteners here at the back of our actuator, two on the side and two in the top. These will line up with the shield. Well first line the top hole fasteners up and install them finger tight. Then well flex the shield down until the side fasteners line up with the predrilled holes in our actuator.
Once they line up well go ahead and reinstall the side fasteners and secure them. Then we can go back to the top fasteners and secure them.That does it for the install of the Titan brake actuator solenoid valve for reverse lockout, part number T4748800 on our boat trailer. .

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
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

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

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

Simple and straight forward. Not often do you get a PO acknowledge and ASN for such a small order as a random customer. Would buy again from etrailer.com based on experience. Only wish - Have freight collect on account as an option for UPS and/or FedEx services. 123988

Replaced the exact OEM solenoid from my Titan model 10. Have it installed but not wired into the system, so functional check will come later. Thank you for the great price and quick shipping. 131080

these work very well and are very easy to install. But they are very fragile, Something saying to view the available video or a note mentioning the fragility would be an excellent idea. 160731
This replaced the original solenoid. Because it's part of the trailer brakes, I had the local brake shop do the installation. Very happy with the product and it works as designed. 251745
As others mentioned the brass is very flaky. Nipple broke inside and it took a lot of time to remove and re-thread. The guys at E-trailer are a class act. Always. Two thumbs up. 184805

Works perfectly, If you have a trailer with surge/disk brakes this is a must. Easy to install. The optional shield (Part # T4835800183) Gives much needed & added protection. 80840
