Specs:
This trailer brake assembly acts as part of your trailer's hydraulic braking system. A hydraulic trailer brake actuator is required for this brake to function.
This brake assembly meets the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. This brake assembly underwent extensive testing to measure stopping distances when braking. This brake has also been tested by QAI for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.
Each shoe on this brake assembly is lined with automotive-grade friction material for improved stopping performance and longevity. The friction material is fully bonded onto the surface of the brake shoe. This lining is custom-molded for a perfect fit. The edges are tapered to ensure long-lasting performance. This taper, along with the circular grinding that the lining undergoes, helps to prevent cracking and crumbling. This durability helps to prevent mechanical lockup, which can occur when brake shoes are excessively worn or broken.
The friction material is also SAE-N certified, which means that it is an environmentally safe product that complies with California and Washington regulations regarding the composition of brake pads. As a result, this material not only provides high-performance braking that can endure the test of time, but it is also environmentally friendly and safe for use throughout the United States and Canada.

Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we are going to take a look at the 10-inch Uni-Servo hydraulic trailer brake assembly for 3500 pound axles, and this is the left-hand or driver side assembly. Now this hydraulic drum brake assembly is designed for use with the surge-type trailer brake actuators. This is a Uni-Servo design, which means it's a single plunger design, as you can see right here. Now the size on this is listed as 10 inches by 2-1/4 inches, and what they are telling you is the 10 inches would be the diameter, which is measured edge to edge, so if we take a ruler and go edge to edge is 10 inches, and then the 2-1/4 basically means the width of the pad on the shoe, so again, when we put that on there, you can see 2-1/4 inches, so 10 inches by 2-1/4 inches, and this is the driver's side or left-hand side. The easiest way to tell that now, all the new ones will come with a sticker that will say left-hand so you know what it is, but if the sticker is not there, the easiest way to tell what side this assembly goes on is just to look at the size or length of the shoe. If you look at this shoe compared to this one, this shoe is larger or longer and this one is shorter, so basically the shorter shoe will always be installed with the shorter shoe facing the front of the trailer, so basically here's the shorter shoe, and if this is the front of the trailer, that means this is the driver's side or left-hand side. Now these brake shoes are lined with a nice automotive grade friction material. This friction material is fully bonded. It is not riveted to the shoes, so it gives you a lot longer life and more braking torque.
The lining also has tapered edges, and then they do a circular grinding to the material to prevent cracking and crumbling that can lead to mechanical lock-up. Now these are manual adjustment brakes, so it does require a periodic manual adjustment on it. The nice thing on this, here's the star wheel that you adjust it with. It does use a fine-tooth gear and that allows for more precise setting, and there is no break-in period needed following your initial adjustment. When you go to install these and do your adjustments, what you will do is go to the back, and you'll notice there are two holes here. These have plugs in them. That's the nice thing about this assembly.
It comes with the rubber plugs already installed. You basically pop those plugs out, you put your adjustment tool in there or your screwdriver, and you can adjust the star wheel to get your setting correct for your brakes. Again, the adjuster plugs are included. A lot of brake assemblies will not include those, but you do want to have plugs in there to keep any dirt from getting into the brake assembly and causing problems, so these do come with that. They also come as you notice with the mounting bolts. This is designed to fit on a four-bolt brake mounting flange, and it comes with the bolts, so all you would need is the nuts and the lock washers.
We do also sell those separately on our website, and they are listed on this page as a related product. Now the backing plate does have an E-coating to it to help resist wear and corrosion. This brake assembly is certified by U.S. SAE standards and the CSA, which are the Canadian standards. Again, the dimension we mentioned is 10 inches by 2-1/4 inches. This is designed to fit a 3500 pound axle, and this does use 10-inch drums. That should do it for the review of the 10 inch Uni-Servo hydraulic trailer brake assembly for 3500 pound axles, and this is the driver side or left-hand side assembly..

I gave the product a 4-star review only because it did not come with lock nuts which meant that I needed to make a quick trip to the hardware store for (8) self-locking fine thread 7/16" nuts. It would be nice to include these with the brakes because the "old" nuts from the original brakes were not fine thread and would not work. The bolts in these are "pressed" in so I couldn't use the old bolts. Pressed in is better, but please consider including the nuts. As for the product assembly, quality and install, it couldn't be simpler. The videos for the install are very thorough and complete. Add the nuts and I would give these a 5-star. I have puchased other items from etrailer and they are a very good source of trailer parts. 430106
Great, still working just fine
Paul T - 09/08/2018
I have been using those complete brake assemblies on my boat trailer and think they are great! What amazed me was how easy it was to replace the old assemblies with the new ones! I owned and operated a tire and auto store for about 40 years and have lots of experience with brakes on cars, truck, motorhomes, etc., but never used a complete brake assembly like this on a trailer. Anyone can do this and I send you a big THANK YOU for such a great product! Keep up the good work! 665136
Fit right on my axles. Much cheaper than rebuilding old brakes! Now I need to repair brake lines. Picture of old brake. 539476
Not sure I ordered the correct part, but it was certainly easy to order and came very quickly. 492492

Perfect fit, great price. 335889
Exact replacement for my trailer with 3500lb. axle. Fit and finish are great, and easy to adjust and bleed the brake cylinder. Would recommend, and would definitely buy products from etrailer.com again. 316865
Product quality was very good for price, quoted delivery ($xx.xx) for three days took 6 days, had it come on time or shipping cost been adjusted, would have rated higher. 310209
have not installed yet but look like a perfect fit 293429
These hydraulic surge brake backing plates bolted right up and work great, I purchased both sides. I can now tow knowing that my brakes are working at 100%. 279377
Very easy install the left side was a little tight with studs included 274500
As advertised! Was able to unbolt old assembly and put on new one. The old assembly had bolts that came through the back plate and nuts on the brake pad side. New assembly had bolts pressed onto the brake assembly facing inward so the nuts were on the inside. Top bolts were close to the axle, but no issues as the nuts went on with no problem. Had to use an open end wrench to tighten, as I did not have a thin wall socket. 242173
Review from a similar etrailer Uni Servo 10 Inch in Accessories and Parts
This product made a huge difference on my boat trailer. The pressed studs are good and "bad" on my opinion. The set I replaced had a standard nut and bolt to attached the assembly. The studs are great, but forced me to use a wrench instead of impact to tighten the nuts on because there isnt enough clearance on my application for a socket. Installed fairly easy and there is a noticable difference in stopping ability. To be fair, the set a relaxed had no braking material and was simply metal to metal. I would def purchase again if needed. Great customer service as well. I got an email to let me know the product shipped, and something I havent experienced before, I also received an email from someone to let me know the parts were delivered! 666432

These are reasonably priced and they were easy to install. they work well even when wet. The only thing that would have made them 5 star would have been to have stainless springs like most marine brakes. 654188
