After calling around to Napa, Koi and 2 other trailer companies and not receiving any help I called etrailer and got in touch with Quinn. I explained what I was needing, and he not only found me the right parts, but he also told me about the house brand which was a cheaper option. Everything showed up in 2 days and fit perfectly.



by: Jason 02/12/2024

Brakes arrived quickly and in excellent condition. The description provided by etrailer matched exactly what I needed. Worthy of five stars. Thank you

My trailer brakes arrived on schedule completely assembled and ready for installation. In 2 hours I had new trailer brakes on my boat trailer working great. Thanks for the great service!

My trailer brakes are still working great. Havent had to give this repair a second thought. Thanks



by: Charles05/09/2021

They installed easily and worked perfectly after some miles I adjusted them and they stop confidently.



by: Jerry 04/22/2020

12" hydraulic drum brakes arrived protected in a well packaged box. Brakes were just as described and very easy to install. I have no hesitation ordering from etrailer again.



by: Henry05/04/2019

Got the 12" backing plates, have yet to install them. My past experience with Etrailer has been excellent! I am rebuilding a large boat trailer and they have had everything I needed to complete the job with great videos on how to install each component. They are the gold standard for an online business!



by: Roy F.12/03/2018

The product was very good with minor shipping damage. I believe it would be better to ship in one box per axle instead of four backing plates in one box, that is where the damage came from. Your people were very friendly,& easy to work with. The product was exceptional quality.



by: Jon07/18/2018

Brake parts were awesome quality.Web site was easy to navigate.Shipping was fast. I highly recommend and will do business again!



by: Sandy 10/02/2020

This brake kit has not been used yet. We are building up a trailer. The mechanic looked them over and says they are great. Thank you!!!

Marine-grade, free-backing hydraulic drum brakes won't engage in reverse, even if your actuator is activated. Automotive-grade friction pads are long-lasting. Dacromet-coated backing plates resist rust. Fit 14" to 15" wheels.

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.

The brake assemblies that we carry do not have hardware included and we mention it on the product pages. In case you want a complete new set of hardware, we offer part # BRKH10B as a quick way to get it.



by: Chris 10/24/2023

The brake kits fit perfectly.



by: William09/27/2023

I’m very pleased with the status provided and the delivery speed on my order. These should have my trailer back in operation today.



by: Walter Collier12/12/2018

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



by: Mike C07/24/2018

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.

Thanks for the help Kelsey!



by: Dan05/09/2023

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.

I am sorry to hear about the boxes and the spring that had to be reinstalled. If there is any more damage then we are happy to take care of it for you. I will have our Customer Service team reach out.

Excellent product that replaced 25 year old brakes on a boat trailer at a fraction of the price that local dealers wanted for them. I found all of the parts I needed by searching the site and everything installed very easily.



by: Ron 03/10/2024

Nice brake units.

Liked being able to ask questions before the purchase and being updated on the shipment of my purchase.



by: Michael04/26/2018

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.



by: Mark04/22/2023

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.



by: Wayne T01/17/2018

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.

Still working great



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

Thanks for the follow up and reply. I did want to let you know that part BRKH10B is available and is linked as a related item. This item included 8 nuts and lockwashers.

  • Comparing Free Backing and Duo Servo Hydraulic Brake Assemblies
  • 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...
