Standard electric brakes need regular manual adjustment to keep them working right. These self-adjusting assemblies stay properly aligned on their own, delivering consistent braking power every time you tow. Measuring 12-1/4" x 3-3/8", they’re built for 8,000-lb axles and fit wheels 15" and larger. With fine-tooth adjustment gears and fully bonded friction material, they give you reliable, even braking without constant maintenance.
Rust, grime, and road debris can quickly wear out unprotected brake parts. These assemblies come with e-coated backing plates that resist corrosion and dust shields that block dirt while you’re towing. The adjuster plugs cover access holes to keep the inside clean so the brakes stay smooth and dependable over time.
Each shoe is lined with custom-molded, automotive-grade friction material that’s fully bonded—not riveted—for more braking torque and longer life. The tapered edges and circular grinding help prevent cracking and crumbling that can lead to lockup. This SAE-N certified material meets environmental standards while giving strong, consistent stops trip after trip.
These assemblies aren’t just built for performance—they’ve been thoroughly tested for it. Certified by the Canadian Standards Association (CSA) and Quality Auditing Institute (QAI), they meet strict standards for braking performance under real-world conditions. That means you get proven safety and dependable stopping power wherever you tow.

Sorry to hear that Merle. Can you please confirm your axle capacity, and is there any numbers stamped on your existing hub so I can see what you currently have? How old is the trailer you are working on? These are 12 1/4", so that explains why they are not fitting your 12" drum, I would like to find you the right parts, just need some more info =)
