R&P Knowledge Hub
Hydraulic brake assemblies use fluid pressure from a surge actuator or electric-over-hydraulic system to expand the brake shoes against the drum surface.
The duo-servo design provides self-energizing braking in both forward and reverse directions, improving stopping performance under heavy loads. These 10K general duty assemblies mount to a 7-bolt brake flange and are typically serviced as complete units.
Before ordering, confirm brake size (12-1/4" x 3-3/8"), axle rating, 7-bolt flange configuration, and correct side.
