All back togeather , working well
The cylinder fit perfectly.
Product just represented, quick shipping and fit perfect.
Product was the exact replacement I needed. Got it installed, brakes bled, and now appears to work correctly.
It was the part I wanted, and it got here pretty quick. I'm satisfied. The picture was better than on other websites, so it was easier to be sure I was getting the right part. (I could see the "R" in this picture.)
I was having a tough time finding the replacement parts locally, so I looked on etralier.com'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 etrailer.com again.
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.
fit and nice to have working brakes aga in.
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
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.
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.
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!!)
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.
Worked great on my boat trailer (2000 Tahoe Q5). Thank you!
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.
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 etrailer.com 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 etrailer.com, so many businesses I do business with throughout the day don't have their level of customer service anymore!
both the replacement wheel cylinders and the brake actuator fit perfectly and function very well, just like new.
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!
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
Brakes were rebuilt with etrailer parts and are working great. Thanks // etrailer.
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.
Thanks!
perfect replacement for my old Atwood brake wheel cylinders.
Exact fit, just bolt on and bleed brakes
It took a while to get here 18 days but the part is perfect I think the problem was US Post not etrailer.com. As Arnie says I’ll be Back, to etrailer.com (but hopefully not to soon because that means I have work to do :) )
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.
Fits perfect, looks to have very good quality. Installation videos were terrific.

A wheel cylinder is a wheel cylinder, this review is about the company that sold me the wheel cylinder. I had trouble finding a replacement locally and just happened upon etrailer via google. I'm always apprehensive when doing business with a company online, especially ones that I've never dealt with before. Let me tell you, I worried a lot about nothing. My transaction with etrailer.com was outstanding. The part look up, ordering process, shipping time and communications were all 100%+ I highly recommend this merchant. In fact off to buy some more parts from them right now :)
These are exact oem replacements. I called the manufacturer of my tow dolly to order the parts and was told they do not stock these parts. I contacted etrailer and within minutes had both right and left parts on the way. Above and beyond for the customer.

I live in BC Canada and spent weeks looking for trailer brake parts, what I thought was going to be a quick and easy job turned into a nightmare. After trying many auto shops I finally found a wheel cylinder that looked like what I needed, except the brake line was too small and wouldn't fit. I then bought adapters...that didn't fit either! I searched online forums to get ideas on where to find parts and all I found was a common message..."if you live in Canada, good luck!"
By this point I have a tandem boat trailer & boat, just purchased by the way, on blocks with no brakes and looks like I'll be replacing everything and spending a lot of money as the only option.
Last Wednesday night I was searching websites and came across etrailer.com. I was shocked to see they had what I needed, I ordered 4 replacement cylinders and the next morning received a confirmation email that my order had been shipped. There was hope after all. On Monday early afternoon...they had arrived and they were the RIGHT PARTS!!! Everything went back together with no problems. I also received a followup email from George saying that he had been notified I received the parts.
etrailer.com is now my go to site for all parts and I recommend them to anyone looking for parts...especially in Canada!
Thanks Guys.
Wheel cylinder was an exact fit, I received it in two days. Could not ask for better service.

Worked great on my boat trailer (2000 Tahoe Q5). Thank you!

both the replacement wheel cylinders and the brake actuator fit perfectly and function very well, just like new.
Thought part would be cast iron like the old one. Not sure what material it's made of. No instructions on recommended torque for brake line nut and bleeder. It matches old one and does fit into backing plate. Will see what happens
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!
Perfect on Prestige boat trailer w/drum brakes
The product was exactly as noted on the website fit and worked perfect. Ordering from etrailer was easy, shipping was fast and packaging was trouble free. I couldn't be more satisfied with the whole experience from etrailer.
Brakes were rebuilt with etrailer parts and are working great. Thanks // etrailer.
Worked flawlessly for replacing my leaky wheel cylinders on my venture boat trailer
Replaced both wheel cylinders on my Atwood system. Perfect fit, easy install.
direct replacement for Atwood and enabled me to get my trailer brakes working again
Fast shipping and parts fit perfectly with the Atwood backing plates I have on the trailer.
Item was a prefect fit for the Atwood cylinder and shipping was prompt. Excellent service! Thanks
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 etrailer.com in the future..
Pictures may follow but order got here in usual ET fashion ((very
fast).
I would recomend offering new bolts along with these for sale.
i forgot the old ones in very rusty cond. I have yet to install so need to .ocal source new bolts and could have saved time if ordering from you.
