Review of Titan Trailer Coupler T1607500

Today, were going to take a quick look at the Titan Primed Brake Actuator for drum brakes, part number T1607500. Now this is a weld-on actuator that you weld to the top of your channel tongue on your trailer. Its designed to be used with hydraulic drum brakes and it may not be the best application for disc brakes, as it may not supple enough pressure.Its designed to work with 2-5/16 trailer balls. To open the latch, youll pull this safety ring and then you can open the wedge and create enough room for the ball underneath. Well go over more on that in a minute when we can flip it over and show you the underside. Well go over a couple of quick measurements.

From nose to tip it measures about 27-1/2 inches long. Outside width puts us at about 4 inches. Its finished in a grey primer, and after you weld it on you can come back and re-finish it whatever color you like. On the top, theres a chain wrapped around our actuator. This is part of our breakaway mechanism.

Well attach the end of the chain to our tow vehicle, and if the trailer were to ever separate from the vehicle the chain would pull tight and activate this lever engaging the brakes and stopping the trailer. Notice on the top here theres a grease fitting for the rollers inside to help keep the operation nice and smooth. Theres also a plastic cap here that you can just pry off with a small screwdriver that allows you access to the fill cap on the brake fluid reservoir beneath. At the back of the coupler, youll see a brass fitting on the end of our master cylinder that you can use to connect to the brake lines on your trailer.Now well take a look at the underside of the actuator. The main outer tube is fully enclosed to help protect the internals inside.

As you brake, your trailer will lean forward against the vehicle and my outer and inner tubes will compress activating the master cylinder inside and sending pressure out of the brake line to the brakes on your trailer.Lastly, well show you how the system works with your trailer ball. Inside the socket area, youll see here towards the back, theres a piece of tubular metal thats going to sit against the back of your hitch ball. If we undo our latch, that piece of steel moves up and out of the way to provide enough room to get the ball in or out. We have a 2-5/16 ball with us and well show you how it works. With our latch opened up, we can get our ball inside, then well let it close and the piece of metal come down and bites on the back of the ball keeping it secured inside the socket.

You unpull the latch up and the ball will come free. Thats it for our quick look at the Titan Primed Brake Actuator from drum brakes, part number T1607500.

I need a video doing the installations and the Bleeding from it

Patrick B.


We have not yet had the opportunity to install this actuator on a trailer. When we do, we will be sure to film it. The bleeding process will be very similar from one actuator to the next. I have added a link to a video where one of our installers does a set of hydraulic disc brakes on a boat trailer. Toward the end of the video, we show the bleeding process.
