I restored an old concrete buggy that I purchased surplus from a rental company. It was in pretty bad shape. I got it sand blasted. I painted it with Rustoleum. I installed new brake parts, master cylinder, and wheel bearing kits. Pretty big project but it came out great! Now I have a great little dual-axle dump trailer designed to carry a cubic yard of ready mix. Works great for short loads of concrete and for drain rock and landscape materials too.

I had to use JB Weld to get a good seal on the new plastic master cylinder cylinder-to-brake-hose connection, which was a pain because it leaked and required multiple attempts to fix. Plastic threads on the plastic master cylinder didn't seal with teflon tape. They are easy to over torque/strip! Maybe I did that initially, but JB Weld fixed the problem.

etrailer brake assemblies were easy to install and of very good quality. Fast shipping. Thanks!

This review is for the Hydraulic Brake Kit - Uni-Servo - Free Backing - Dacromet - 10" - Left/Right Hand - 3,500 lbs - AKFBBRK-35-D. This worked perfectly on my 2008 Bear pontoon trailer with Axis branded 3,500 lb tandem axles and hydraulic surge brakes on one axle. It all went together smoothly without issue and after repacking the bearings and bleeding the system, the brakes now work again. A special thanks to Jameson for your time and recommendation on this kit, it was spot on!



by: David 01/13/2024

Nice. Perfect replacemen. For the price ace sends to just replace the whole loaded assembly vs pieces parts.



by: Tim07/05/2023

The quality of the unit seems fine, however they manufacturer is so cheap that they do not include the 8 nuts to hold the brakes to the axle. They expect you to to use the old nuts, in a perfect world that would be fine. Assuming your old bolt bolts and nuts are the same thread! Spent another $12 on nuts which is it a big deal but the hardware store was closed so I had to wait till the next morning. Wont order again.

None of brands of brakes that we carry will come with the nuts or lock washers. We mention this on the product pages for the brakes. Some want to re-use what is on the trailer and some want to replace it. We do carry a replacement set as part # BRKH10B.



by: Donald06/05/2023

The brakes work great. The new assembly had studs for mounting to the trailer and the nuts and washers were not included, so I had to get my own. Your information for ordering should make that clear.

Here is some pictures of the before and after pictures of my boat trailer brake restoration. I contacted your customer service and told them what I wanted to do and they sent me all the parts that I needed. Everything went very smooth and all parts fit perfect. Thank you so much for your help and expert advice. Thanks again

Fantastic way to repair brakes on trailer. Actually less cost than buying individual parts to complete the job. Both sides completed in under 2 hours. Will be sure to tell everyone i know that has trailers to used this site for all of their needs. This is the 2nd trailer we have done brakes on,

Extremely happy i found this site.

The boxes containing the brake kit was badly damaged due to transit. One of the springs popped off and the brake shoes were no longer aligned properly. Packaging was extremely poor. Hopefully there is no damage that I couldn’t see.

The loaded marine grade backing plates made my job super easy. The fit was perfect and went smooth. I would like to see new nuts supplied with the studded backing plate. My order was processed fast and I received it quickly. Packaging was great.

just installed brakes,install ok.just hoping to get more milage and time out of these brake .because in the past i have not,i have had cylinders lock up on me on both sides, mechanical issues sitting on the side of the road stinks.but i have also learned that these brakes are not install and go .they need to be adjusted thru out the year for better wear



by: Patrick06/02/2023

Backing plates arrived on schedule. Installed just fine.

My new brakes look and fit great. This made the replacement on my Heritage boat trailer very easy. The quality looks great and should last me a long time.
Thanks etrailer for your help!



by: Chris04/18/2022

I installed these on my 1995 dual axle DHM trailer which carries my '95 closed bow Ski Nautique. The finish is stout and set up very easy. Had a bit of a challenge installing one nut on each side due to close tolerances between the backing plate and axle support but once on, the remaining three when on easily. Recommend doing this over trying to replace just the shoes.



by: Dave 08/30/2022

Had to replace the old 20+ year old Attwood brake system. Both the brake assemblies and the coupler are working great.



by: Tye01/10/2022

The product looked great and I got great service. I was unable to use the brakes, though because I needed 5 hole backing plate instead of the 4 hole backing plate. I never got around to seeking a return, my fault.

by: Bruce S12/15/2020

Good product, fit very well and easy to adjust when installed ( lubricated the adjuster anyway) After a year of in and out of the salt water once a week for the season they look very good, a little rust, but not bad. Will see next year how they stand up.

Update: brake pad came off and locked up trailer wheel yesterday. Told only 1 year warrantee on workmanship issue. 2 years and now I need new brakes because they failed.



by: MNDIY05/27/2017

Very, very prompt shipping!
Customer
svc rep very knowledgeable about hydraulic trailer brakes.
Packaging ensured product arrived without damage.
TWO NOTES: The brake line threads were not "well cut" on the right side wheel cylinder. To solved needed to "re-tap" the threads-- additional time required--
To make kit 'complete'--add 8 lock nuts to the package--will add about $0.80 to the kit and solve customers frustration of trying to find lock nuts with 5/8" across the flats. 11/16" across the flats will not work as too close to the welded axle on the mounting flange

  • Good questions. The difference between free backing brakes like the # AKFBBRK-35-D and regular hydraulic drum brakes like # DMSB18794M-93M (referred to as duo or duel servo) is that the wheel brake cylinder has pistons on both sides of the regular/duo servo brakes instead of just the one side on the single servo free backing assemblies. The amount of braking doesn't change much between them, they just function differently yet under the same amount of hydraulic pressure. The duo servo...

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.



by: Chuck D.09/21/2020

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 almost

Its been a year now since I have installed the hydraulic trailer brake kit assembly and drums to my boat trailer and they have been working as great as the day I installed them. No issues



by: Garrett T.03/18/2020

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.

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.

Very good parts, good service, shipped quickly

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.

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.

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.

by: Nick07/19/2019

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.



by: John10/22/2018

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.

by: James05/26/2021

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.



by: Rich05/08/2019

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.



by: Raymond10/07/2020

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.



by: Lloyd04/16/2020

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.




by: David02/29/2020

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.

David



by: Jerry08/19/2019

The brake assemblies were a direct replacement for the OEM part. Installed easily. Can feel the brakes working smoothly when towing my bass boat. etrailer was fast at shipping the product. Time will tell how durable and corrosion resistant they are.

  • Comparing Single and Dual Servo Hydraulic Drum Trailer Brakes
  • The only difference between single and dual servo hydraulic drum brakes is that dual servo will provide more force while in reverse than single servo. That said, it's not much and most really don't use their brakes a ton in reverse so single servo like the Hydraulic Trailer Brake Kit part # AKFBBRK-35 are far more common. I have attached a list of our hydraulic brakes below, if you need help picking out a set I would just need your axle capacity.

  • Comparing Different Hydraulic Trailer Brakes for Boat Trailer
  • Essentially yes, all of them will work for your trailer assuming you have 3,500 pound axles and a 4 bolt mounting flange. However, there are some differences between the brake assemblies you mentioned. The # AKFBBRK-35 are free-backing brakes, meaning they will not engage when reversing with your trailer. If your trailer has a reverse lockout on it then this feature is not necessary. They're coated with an e-coat used for corrosion resistance. The Demco brakes # 40716-15 are galvanized...

  • Difference Between E-Coat and Dacromet on Trailer Brake Kit
  • The e-coat on the # AKFBBRK-35 is basically a paint that uses an electrical current to apply it to the surface. The Dacromet coating on the # AKFBBRK-35-D is a water-based adhesive coating made of zinc and aluminum flakes. The part is dipped in the coating and then heated for a uniform application on the surface. The Dacromet is a much better choice for applications where corrosion resistance is important. That is why we list it as ideal for boat and snowmobile trailers.
