I purchased both sides for a 1978 Easyloader Trailer (Adjustable Type) and they work great.
Quality construction.
Easy installation.
Fast delivery.
Had to grind a little bit on the shell to make it fit my break wheel plate.
Only the L side, the R side fit without trouble.
Mounted and bleed the breaks with out any problems.
Information was included on the mounting of the master cylinder, which made it easier.
Delivery was free and only a couple days.
GREAT
Received product as advertised although the initial feedback for shipping was a little slow. Installed product on the day received. Looks and performs as expected. Thanks E-trailer!

SEEMS TO BE WORKING GREAT!
I bought a older trailer with surge brakes that needed the master cylinder replace wheel cylinders and shocks for the actuator local parts store didn't have a clue and didn't want to be bothered I looked on line and found etrailers Web site and they knew exactly what I needed and we're very helpful and polite to me. l had my parts two days later they email you when product shipped and when it arrives at your home
I'm pleased with my experience with ETrailer. I ordered this trailer brake actuator as well as 2 wheel cylinders on a Monday evening and received it on Thursday evening. They emailed me throughout the whole process to let me know the status of my order. The price is very exceptional and the quality of the parts are very good as well. I would recommend to a friend any day!
I had an older trailer and was able to identify all the components I needed by looking at the pictures on the web sight. Found everything I needed, ordered and it was at my door 3 days after shipping. All parts where what I needed. Excelent.
Incredibly fast shipping and one of the easiest companies to work with! I haven't installed the wheel cylinders or replacement master cylinder just yet but the quality of the parts lead me to believe I won't have any problems!
I ordered on a Monday and had the parts in hand on Wednesday!
The product works great. I have a 1974 boat trailer that I could not find parts for anywhere local so I called etrailer and they looked up the part in just a few minutes. Very satisfied with the parts and customer service. Will do business again. Thanks
Although taking apart the brake assembly was a bear, I was pleased that the installation itself was easy with no surprises.
Repairing a old trailer but Sandy was very helpful in finding the right part. Quick shipping, received parts in 3 days parts fit good just what I needed. Thanks for the good service.

I replaced all four of my 20 year old wheel cylinders on my trailer. The original company Dico is now called Titan. These replacement wheel cylinders were machined to as exact a fitment as I could tell. I had no trouble mounting them to the brake assembly. (Always use new bolts!)
The only issue I had was in one of the cylinders bleeder valve orifice. A small amount of rust had managed to form in the threads. I suspect localized moisture immediately after production led to this. I sprayed a rust dissolving solvent into the bleeder orifice and that made it look new again. Wheel cylinders work as they should.
I was pleasantly surprised that I could get the bolts out of and the brake lines off of my old cast iron wheel cylinders but I did. The new cylinders from Etrailer went in easily. Better still is that they will last much longer made from zinc coated metal.
They bled out their air and now perform just as if it is a brand new trailer....great! The staff and service of Etrailer is really very good, you can tell that they are more than just words but are indeed sincere.
