10K Hydraulic Trailer Brake Assembly – Right Hand

Description The 10K Hydraulic Trailer Brake Assembly, part #31-B1210H-2, delivers reliable hydraulic stopping power. It is built for 10,000 lb trailer axles. As a result, it performs well in commercial and equipment-hauling applications. This right-hand (passenger side) assembly uses a proven 12.25″ x 3.375″ drum and shoe design. Therefore, braking stays smooth and predictable on flatbeds, dump trailers, equipment trailers, and fleet units. This hydraulic brake bolts directly to a 7-bolt brake flange. It installs as a direct replacement for many Dexter 10K hydraulic brake assemblies. In addition, it fits other OEM axles that use the same 12.25″ general-duty hydraulic platform. The built-in free-backing feature lets the trailer reverse without dragging the shoes. As a result, wear drops and control improves in tight spaces, job sites, and loading docks. Part #31-B1210H-2 ships fully assembled. It includes the hydraulic wheel cylinder, bonded brake shoes, return springs, and free-backing hardware. Because everything comes pre-installed, technicians save time. Fleet maintenance teams also get trailers back in service faster. For best results, burnish the brakes after installation. First, tow the trailer in a safe area. Then apply the brakes repeatedly from a steady speed. Use moderate pressure. Avoid hard or panic stops at first. This process seats the linings evenly and delivers consistent braking under load. For anyone needing 10K hydraulic trailer brakes, Dexter-compatible assemblies, or free-backing hydraulic brakes, part #31-B1210H-2 is a dependable choice. It offers durability, quick installation, and confident stopping power. Additional Part #: 10GDHYDRHBRKAS, K23-411-00, 77-1210H-2, BK-10KH-02
