It uses a 12-1/4" x 4" semi-metallic shoe and features a forward self-adjusting mechanism that automatically maintains proper shoe-to-drum clearance as the linings wear. Rated for 10,000 lbs per pair (5,000 lbs per brake), it mounts to a 7-bolt brake flange and provides reliable stopping power for large utility, cargo, or boat trailers. This assembly is commonly replaced when brakes are worn, damaged, or require a self-adjust upgrade.
