Standard electric brakes need periodic tweaking to stay in tune. These self-adjusting assemblies automatically keep the brake shoes properly aligned, so you get consistent performance without crawling under to make adjustments. The 12-1/4" x 5" size and 7-bolt mounting pattern are built for 12,000-lb axles and wheels 15" or larger, giving you heavy-duty braking that stays dialed in mile after mile.
Each shoe is lined with durable, automotive-grade friction material that’s fully bonded—not riveted—for lasting strength and more braking torque. The tapered edges and circular-ground finish help prevent cracking and crumbling, reducing the chance of mechanical lockup. SAE-N certification means the pads meet environmental standards while still delivering dependable stopping power every time you hit the brakes.
Brakes can take a beating from dirt, gravel, and road spray, but the e-coated backing plates on these assemblies resist wear and corrosion. The included dust shields keep grime and debris out of the mechanism so your brakes keep operating smoothly. Even the adjuster plugs are designed to seal up access holes and block out contaminants that shorten brake life.
These assemblies are QAI and CSA certified after extensive performance testing under real-world conditions. They’ve been evaluated for stopping distance, braking strength, and long-term reliability to ensure they deliver safe, predictable control under load. You get ten left-hand and ten right-hand assemblies ready to mount—just add the required hardware (sold separately) and connect your electric brake controller.

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 =)
