  • Electric brakes are easier to install and offer more user control than hydraulic brakes
    • Require only an electric brake controller (sold separately) - no actuator or hydraulic lines necessary
  • Automotive-grade friction material is molded to brake shoes
    • Pads are fully bonded - not riveted - to shoes for long life and more braking torque
    • Less chance of cracking and crumbling that can lead to mechanical lockup, thanks to tapered edge and circular grinding
  • Self-adjusting brakes do not require periodic manual adjustment like standard brakes
    • Fine-tooth brake adjustment gears allow for a more precise setting
  • Dust shields protect from debris while you're towing
  • E-coated backing plates resist wear and corrosion
  • Adjuster plugs (included) cover access holes to keep dirt and grime out of the assemblies and off of the shoes
  • Left-hand (driver's-side) brake assembly and right-hand (passenger's-side) brake assembly included
    • Mounting bolts and hardware (BRKH122508) sold separately
  • QAI and CSA certified


  • Application: most standard hub-and-drum assemblies, including Dexter and Lippert (LCI)
  • Dimensions: 12-1/4" diameter x 3-3/8" wide
  • Mounting flange bolt pattern: 4 bolt
  • Wheel size: 15" or larger
  • Axle rating: 8,000 lbs
  • Limited 1-year warranty

Self-Adjusting Brakes Don't Require Routine Adjustment

Standard electric brake assemblies require manual adjustment of the brake shoes over time to provide longer-lasting and more efficient braking performance. With self-adjusting brakes, the brake shoes are always properly aligned, so there's no need to manually adjust the brakes after the initial adjustment. As a result, you get optimum performance without having to take the time to continually perform this type of maintenance.

Thoroughly Tested for Safety

These brake assemblies meet the requirements for certification by the Canadian Standards Association (CSA). The CSA creates standards, which when complied with ensure a safe and quality product. These brake assemblies underwent extensive testing to measure stopping distances when braking. These brakes have also been tested by QAI for braking performance in a complete automotive setup and under real-world conditions to provide the most realistic scenario for the everyday driver.

Automotive-Grade Friction Material

Each shoe on these brake assemblies is lined with automotive-grade friction material for improved stopping performance and longevity. The friction material is fully bonded onto the surface of the brake shoe. This lining is custom-molded for a perfect fit. The edges are tapered to ensure long-lasting performance. This taper, along with the circular grinding that the lining undergoes, helps to prevent cracking and crumbling. This durability helps to prevent mechanical lockup, which can occur when brake shoes are excessively worn or broken.

The friction material is also SAE-N certified, which means that it is an environmentally safe product that complies with California and Washington regulations regarding the composition of brake pads. As a result, this material not only provides high-performance braking that can endure the test of time, but it is also environmentally friendly and safe for use throughout the United States and Canada.

only complaint was that one (2) sets ordered one of the backing plates was wrong - so have to swap parts over to old backing plate but everything worked as should -

It sounds like one of the brake assemblies shipped was incorrect. I will have customer service reach out.

I replaced my brakes on our fifth wheel with these, and they worked out great fit perfect and perform well


Product fit and worked as it should would order them again for several other trailers that I own, just wish shipping would have been more timely.


I am usually not one to buy aftermarket parts, I always prefer “Made in USA”. However these brake assemblies were better then expected and fit perfectly. I’m yet to see the wear factor but they look good.


Parts where exact fit for dexter 8k axles,great value and appears to be well a manufactured assembly. Order fulfillment customer service was excellent!Items was shipped proto and well packaged. This was first time doing business with etrailer, definitely will be back!


The brake assemblies were easy to install and perfect fit, and are still working great. Impressed with them would buy them again.


Sent wrong parts, called service said they would ship right ones, never happened. Took about 4 weeks to get refunded . Was a mess


Brakes work as they should on my 2004 Elite horse trailer. Easy to install. The break in period is important as when I first installed braking was not good, but after break in period they work excellent.


Takes too long to receive parts.

We apologize for the delay in your order arriving. I see you have placed your order in our busy season. We do have some expedited shipping options that would guarantee your order to arrive at a specific time.

Great affordable product and excellent customer service!


User friendly website, fast delivery and proper fit. Price on 4 new brake assemblies were the same as my 2 local dealers, which didn't have anything in stock.


Exact replacement


Way cheaper than original Dexter and came w/ a shield. It's looks exactly the same and performs like Dexter, but you save a lot money. My friend saw these on my trailer and couldn't believe how much I paid. So, he had me order 4 set of them for him. I just torch off old mounting bolts and the brake assembly fit perfectly. My trailer is used mon-fri for work. Now, I have working trailer brakes.




The parts fit like the originals. Save lots of time in ordering the parts from etrailer.

The brakes work like new. no problems.

Exactly what I ordered. Looks like a good product, haven't used the RV yet to try them out. Fitting was straightforward. My only disappointment was not getting a break on delivery cost to Canada but......
Good overall service from Ashley, would order again from etrailer if I needed anything


Excellent service. I ordered on the 29th (evening) and all items were here afternoon of the 31st! The customer service rep. helped me find the exact replacement parts that worked for my application. The pricing was a lot better than I could find on the internet or locally. I will definitely order from etrailer again.


Product delivered as ordered. The price was the best/lowest I could find. Have just installed four trailer brake assembly’ and it went well. Very happy!!


The complete brake plates fit and worked perfect.I will be replacing the other two on my trailer this winter.


all the detailed information on your site was so helpful to know the parts would fit. items were shipped faster than expected, thank you!


Brakes are great, and stay in adjustment. 60k on them in less then a year.


Fit perfect on my Dexter axles and a lot cheaper


Great Price, good looking product. Will tell how well they work when we start using trailers this spring


Great price, great quality!
About a
year as I installed them, had zero problems!
