If your trailer’s factory brakes are dragging or worn out, these etrailer 10" x 2-1/4" electric drum assemblies rated for 3,500 lbs are a direct bolt-on fix. They include both left- and right-hand sides and fit standard 4-bolt flanges found on most hub-and-drum setups. The bonded automotive-grade pads deliver strong, even braking torque without the chatter or scraping that comes from riveted shoes. Just match your 13", 14", 14-1/2", or 15" wheels and you’re ready to roll.
The pads use the same friction material found on car drum brakes and are SAE-N certified for performance and environmental safety. Because the pads are fully bonded to the shoes, there are no rivet cutouts to interrupt contact with the drum—so you get more friction area and smoother braking. The tapered pad edges help prevent the grabby feel or lockup that can happen as the shoes wear down, keeping your stops stable and predictable.

Road grime and moisture can corrode standard brake parts fast. These assemblies use e-coated backing plates that fend off rust for longer service life. The included adjuster plugs keep dirt out of internal components, and the QAI, CSA, and SAE-N certifications verify quality you can count on mile after mile.
You don’t need special tools to keep these brakes in tune. The manual adjuster lets you set shoe tension through access holes in the backing plate using a flathead screwdriver or brake spoon. When properly adjusted, you’ll feel a light drag as you turn the wheel by hand—ideal for maximum braking efficiency. With only two wires per assembly and included mounting bolts (nuts and lock washers sold separately), installation is straightforward for any hands-on trailer owner.

Glad to hear it bolted right on, Lonnie! Brake are a pretty important part of the trailer, so it's always nice when they work properly and are easy to replace when needed. ^___^ Any more trips planned for the year? It's definitely starting to get cold, which is the best time to go out into the wilderness in my opinion!
