The surge brake equipment of your trailer consists of the brake lines, drum brakes and the brake actuator. To ensure I recommend the correct parts for your trailer I will need a little more information.

A brake line kit is pretty universal. For a single axle trailer, I recommend using part # T4829900. This kit comes with all of the lines and fittings you will need to replace everything from the actuator to the brake assemblies.

For an actuator, I would need to know what type of actuator you currently have and the overall weight of your trailer and boat. Some boat trailers have actuators built into the channel of the tongue. We do not carry these actuators, but if your actuator is simply welded or bolted to the tongue, then we can find a replacement that will work for you.

There are several different options for brakes. All of the 10 inch hydraulic brake assemblies we carry use a 4 bolt mounting pattern, so you will want to make sure your current brakes use a 4 bolt pattern as well to mount to the brake mounting flanges on the axle. If they use a 4 bolt pattern, then you could use our Titan Uni-Servo Hydraulic Brake Assemblies, # T1878700 (right side) and # T1878800 (left side). If your actuator does not have a lockout, then I recommend going with free-backing brakes like part # T4071500 (right side) and # T4071600 (left side).

If you load and unload in salt water, then I recommend using galvanized brakes like part # 18787 (right side) and # 18788 (left side). All of the brake assemblies I mentioned fit 3,500 lb axles with drums that have a 10 inch inner diameter.

I have attached a help article that covers all parts needed to add hydraulic brakes to a trailer. It covers all of the parts that you need and how to choose the correct parts for your trailer.

Answer 1

Going to electric over hydraulic is probably a bit of overkill, and disc brakes will serve you very well, but without the locking up. So that's the route I recommend, and since you have a 5 on 4-1/2" bolt pattern it is likely you have a…

The Titan brake actuator #T43397007K will take 1/2 inch by 4 inch grade 5 bolts, nuts, and lock washers. Since this is a boat trailer if you can find some grade 5 zinc coated or stainless steel they will have better corrosion resistance. I have…

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…

To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…
