Speaker 1: Today we're gonna take a look at the replacement right-hand Uni-Servo wheel cylinder for 10 inch and 12 inch brake assemblies. Now this part will replace the hydraulic wheel cylinder that's on the right-hand side of 10 inch and 12 inch brake assemblies, that are manufactured by Dexter, Bendix, Dyco, Demco and Atwood. This wheel cylinder is the right-hand configuration, so it's the passenger side. And it is a Uni-Servo design, which means it's a single plunger design. This does have a zinc plating, to help resist corrosion. And it is made in the USA.

But that should do it for the review on the replacement right-hand Uni-Servo wheel cylinder for 10 inch and 12 inch brake assemblies.

You had the cylinders that I needed for a brand that was no longer available, thank you!


The wheel cylinders arrived quickly and were easy to install. I expect they will hold up well.


Great customer service and really quick shipping on my order. My trailer's LH Wheel cylinder was leaking and I called etrailer to make sure I would get the right one for hydraulic bakes/backing plate for my trailer. They were really helpful and gave me two mfg options.The option I chose turned out to be an exact match for my old wheel cylinder. I also ended up ordering both the LH and RH wheel cylinders figuring a RH cylinder failure was probably not far away and it was the same cost to ship both. The only reason I did not give this a 5 star rating (and I wasn't offered 4 1/2 stars) is because the packing on the shipping was not great. The RH cylinder was sent to me without being in its its original packing and was bouncing around inside the box (not enough bubble wrap)but it otherwise appear OK and the seals were undamaged. I installed the LH cylinder, bled the brakes and it works fine and I am very pleased. Overall a solid job by etrailer and I would buy from them again for sure.


This product fit perfectly and was priced very good. Shipping was fast too. This is the second part I have pruchased at e-trailers and would purchase parts again.


It took a while to get here 18 days but the part is perfect I think the problem was US Post not As Arnie says I’ll be Back, to (but hopefully not to soon because that means I have work to do :) )


This unit fit my Master Craft tandem trailer. It was an exact match to original equiptment. Customer service was helpful, Shipping was extra fast and the price fit the budget. etrailer has always had the best price, best customer service, and fastest shipping at the best rate. Thanks Nicky K at etrailer

perfect fit, no problems

The brakes were "supposed" to be in working order when I bought the trailer, but I found that both wheel cylinders were rusted and frozen. These new wheel cylinders were an exact fit for my Venture boat trailer, which made for a nice easy installation!! I added a bit of thread anti-seize to the threads of the bolts, brake line, and bleeder threads to ensure that corrosion doesn't make them impossible to loosen.
(Suggestion: When buying a used boat trailer, bring a floor jack and test the brakes before you buy!!)


Had a hard time finding part numbers for these brake cylinders. Shorelandr was little help but ETrailer verified what I thought I needed and in fact they installed fine.
Thank you for your help.

Wow. Well I sold the boat and trailer this spring, however, all I can say is the brake cylinders were exact replacement parts and work fine.Thank you.

Worked flawlessly for replacing leaky wheel cylinder on my venture boat trailer


Product has been installed one year and is working as expected. Easily installed in place of old rusted cylinder and after bleeding trailer brakes, boat and trailer with surge brakes were off to the lake. Price was very good and delivery was quick.


Our mechanical staff decided to replace the wheel cylinders rather than the complete assemblies. The cylinders are nice quality at least as good as OEM. They arrived well packed and a day before expected. The staff at were great from start to finish. George J was helpful with the placement of the order and letting me know through emails on the progress of the order. When it comes to getting invoices for our finance department, one call to Preston M. and I have then in my email before I even hang up the phone! It is an absolute pleasure doing business with, so many businesses I do business with throughout the day don't have their level of customer service anymore!


We bought an older model horse trailer with no manufacture name and we were finding it impossible to find parts for it until we came across etrailer. Thanks to you we have new brake lines and wheel cylinders. As soon as my husband puts it all together we are ready to roll. Thank you.


both the replacement wheel cylinders and the brake actuator fit perfectly and function very well, just like new.


perfect replacement for my old Atwood brake wheel cylinders.
Exact fit, just bolt on and bleed brakes


I have actually installed one side of the brakes, and the wheel cylinder fit perfect. The hose was a perfect match also. Thanks for providing a great product at a better than the national auto chain prices with shipping included!


Worked great. Product as described.


Everything fit and worked just as I hoped it would. Your Customer assistance was outstanding in helping me find what I needed.
I will not hesitate to buy from in the future..


I was having a tough time finding the replacement parts locally, so I looked on's site. They not only had the exact parts I needed, but they delivered the parts to my home within two days of placing the order and I even placed the order on a Sunday afternoon. The customer service followup and communication was excellent. I will definitely be using again.


The product and customer service were refreshing and excellent.


Extremely quick delivery to Canada just using the basic USPS/Canada Post option. I will recommend you to my Canadian friends, the speedy delivery was especially Helpful since I can not go tu my usual US pickup point.
The parts look good and correct, but I have not yet installed them on my tri-axle boat trailer.


Brakes were rebuilt with etrailer parts and are working great. Thanks // etrailer.


Replaces old part exactly


Product was exactly what I ordered and is of high quality. Only problem I have is shipping is slow. Its common to have items ship the same day as payment and have them delivered within 3 days


Fits perfect, looks to have very good quality. Installation videos were terrific.


The bleeder fitting required a 10 MM rather than the 3/8" it replaced. Otherwise it was a perfect fit. Shipping and receipt were very prompt.
