Hydraulic Trailer Brake Kit - Uni-Servo - Free Backing - 10" - Left/Right Hand - 3,500 lbs

I did a total rebuild of my boat trailer. I ordered nearly all of the parts from etrailer. New carpet for the bunks new brakes and backing plates as well as a new brake actuator. New wheel bearings and seals. This trailer is old a 1974 but all of the parts fit I was satisfied with all of the products I received and the timely manner in which they were delivered to my door I am very happy with the fine service I received a t trailer and the help and selecting the right parts thank you very much etrailer.592909

They are a nice unit but the included studs need to come with lock washers and nuts . I had to drive out the studs and use my old bolts nuts and washers .1650738

These replaced a set of brakes that had been on the axles for 20+ years. Brakes installed as expected, all fit great. Bleed the brakes and they are working great. Great purchase1622550

Excellent perfect match for my 2005 Jayco Baja trailer. Easy peasy to install. To make it easier to get the brake line threaded in... start it prior to bolting it into place.1326250

Products are great customer service well…….
I ordered the product on the 10th was suppose to be here the 17th called customer service the 17th guy tells me he apologizes the warehouse guys are slacking. They were unable to locate one of the items I ordered that’s why it hasn’t shipped. Not once did anyone reach out to me to offer to substitute. I am not some weekend trailer fixer upper. That might order 2-3 things a yr. I own a trailer rental company with 12 trailers in my fleet. I asked for over night shipping to get the items Friday so I could still meet my deadline by Monday as this particular trailer was scheduled to be rented starting Monday morning the 21st for 2 weeks. Your customer service agent said sorry we can’t offer overnight shipping on this order as we would be losing money…(had someone reached out to me between the 10th and 15th I would of had my order my the 18th) ….. well because of incompetent etrailer employees. My order was shipped ground despite requesting overnight shipping I lost a $3,000 dollar rental….. Because of that I am willing to pay double for a trailer part before I order from e trailer again.1275446

I will have our Customer Service team reach out to you.

Got everything installed and after testing, brakes are working well. I have no major complaints. Price is good. I could have spent a few extra dollars for the galvanized backing plates but this is for a boat trailer that only gets towed 25 miles or so each way to a freshwater lake once or twice a week during the summer, so I went the cheap route.

A couple of notes: spend the 5 bucks on the accompanying hardware kit (nuts and washers). I didn't, figuring that I would just use the nuts and washers off of the old plates. Problem is that the bolts on the old plates were course thread and the bolts on these are fine thread. I had to go to about 4 stores to find fine threaded bolts in the right size. I would have saved myself a couple of hours on the install if I would have ordered the hardware from etrailer.

Second, on my trailer, two of the bolts were stalled with the bolt head on the outside of the axle with the nut on the inside of the plate. With these new plates, the bolts are not removable, which meant that I had to install two of the nuts with an open end wrench rather than an impact socket because there was not enough clearance between the nut when threaded onto the bolt and the axle. Not the end of the world and even if I knew that in advance I would have still purchased this same product. But it did end up taking an extra few minutes for each axle to install the plates, so it is something that I thought that I would note here.

Just a couple of quibbles that were specific to my trailer. But if I were to do it over again, I would still purchase. 767199

Still working fine.

It’s the right product for the correct application at a good price and good quality.1585749

My trailer is over 25 years old and my concern was if I was going to be able to get the right parts. Everthing was still the same as back then. Much easier to replace the whole Assembly as opposed to randomly replacing a part here and there. I now have a new trailer...well almost884232

After one year the brakes are performing great. I would buy again when they need replacement.

The FREE BACKING trailer brake is the way to go. No more having to lock the system out before you back up. No more forgetting to lock the system out before backing up. Had this for a year now and it works like a champ. I love E Trailer, they have everything for my 5 trailers.1288760

I have ordered complete brake assemblies like these in the past for my 5th wheel. They are great and easy to install. No need to fight those springs and keepers that hole the brake shoes to the backing plate, (Pain) just remove the wheel and four bolts, install plate and wheel and adjust the brakes. Done in less than 30 min. a wheel. You save time and money! Great way to do your brakes and I like E-trailer's fast delivery.897861

The brakes I order were easy to install and work very well. Have ordered other ltems all were received fast and on time thanks etrailer will be ordering again soon

Excellent service started when I called to ask a question about my order. She then answered all my questions and took my order. I received a follow-up call the next day to make sure of my address. I placed my order on Thursday and received my item on Tuesday. Great service all the way around. I also went to a place that builds trailers and they couldn't even get what I needed this cheap with their price.1370602

I have had nothing but problems with the backing plates. I have adjusted them about every time I have taken my boat out. One time my boat trailer locked up both tires going down the road about 35 mph. good thing it wasn't any faster or I would have been in the ditch. I'm going to change back to the Manuel lockout brakes once I can get all new drums and brakes. 672443

Great product,. Shipping took longer than expected and quoted but product is good1557512

Shipment arrives on time as promised and they sure look good. I have a dropped axle trailer and I installed with the traditional adjuster at 6 o'clock position but with my dropped axle, I was not able to adjust the brake from outside. So I called etrailer help desk and the lady took down all my information and told me someone will call me back within 24 hours and they did and gave me a sound advice. Clock the plate so that the left adjuster will be at 9 o'clock position and right adjuster will be at 3 o'clock position. I did it yesterday, adjusted the brakes from outside, bleed the brakes and it works like it should be. Thank you etrailer and your supporting team.1047030

Great service. Arrived early,fit perfectly on my 1989 mastercraft trailer. The only complaint that I have is that the ports for adjusting the drum brakes are blocked by the vertical part of my trailer axle. I believe this a just a poor design of the axle because the original brake backing plate adjusting port was in the same spot. Had to adjust by adjusting out until I couldn’t get the drum on,then pulling drum off to adjust the brakes in until the drum would fit on again.898538

Delivered in a timely manner. one shoe had slight damage but not bad enough to complain about. Have heavy boat that I bought used 4 years ago and trailer brakes had never worked. These bolted on easily, made slight adjustments and trailer brakes now work perfectly. Should have done this a long time ago.

Very happy, will order from etrailer again if needing brake parts.639864

This is a great value for a right and left pair of complete drum brakes (except the drum). They were well made and fit up perfectly. My biggest problem was getting the old, rusted bolts and nuts loose. I was replacing a very rusted brake that had been used in salt water for about ten years.

I looked into changing to disk brakes and Dacromet coated was 4 times more and SS almost 10 times more so I will just replace these every 5 years.

This brake assembly uses studs and nuts (nuts not supplied) and the old one used bolts and nuts. Took a little bit of work because the bolt head on the old one didn't move and there wasn't enough clearance to get a socket around it. A little grinding solve that though. This is really a fault of the old axle and not this new brake assembly.

These brakes are a perfect fit for my trailer and were very easy to install. The only drawback is that the 7/16-20 nuts that fit the mounting studs are not included, so if (as in my case) you're replacing bolts with a different thread pitch, you'll have to dig through your bolt jar, run to the hardware store, or order a mounting hardware kit.377930

Could not get my boat home from storage due to bearing and hub failure on the boat trailer. Talked to Tamarah M at etrailer to get the parts needed for onsite repairs. She was very knowledgeable and helpful. When one part was not in stock, she helped to expedite the shipping of the other parts, so I could at least begin repairs. I talked to her on Tuesday evening and the parts arrived on Thursday morning. Very appreciative of the excellent customer service from Tamarah and the entire etrailer crew. I own three trailers, and etrailer will always be my first choice for parts.

Basically I just bolted these on and they were good to go. I bled them. the price is good and every thing is new and clean. Costumer service was real good about answering questions about product. nice to talk to a person when ordering.576469
