Upgrade your trailer's stopping power with this Ultra-Fab self-adjusting brake. It's designed for the driver's side (left) and has a 12-inch diameter with a 2-inch wide shoe, rated for up to 7,000 lbs capacity. The brake shoes are molded with automotive-grade friction material that's fully bonded to the shoe, so they deliver strong, consistent braking and last longer. The self-adjusting feature means you won't have to manually adjust the brakes as they wear down—just install and go. The backing plate is E-coated to resist rust and corrosion, which is great for trailers exposed to weather. Sold in bulk packaging, it's a straightforward replacement part for DIYers or mechanics. Perfect for boat trailers, utility trailers, or other medium-duty applications. Just make sure it matches your trailer's brake system specs.
