Slider Shoe Assembly
SAF-Holland

This slider shoe assembly is a critical actuator interface in drum brake systems, providing the guided contact surface for the moving brake shoe and ensuring consistent engagement with the drum. Built to endure repeated cycling under heavy loads, it combines precision-ground contact surfaces with hardened materials to minimize wear and movement play. VMRS code 059-001-123 places the part in the brake shoes and slider assemblies subfamily, supporting clear identification for maintenance and replacement planning. Category 42798 indicates its role within the shoes and related slider hardware. In practical terms, technicians replace slider assemblies during overhauls or when wear reduces braking efficiency, improving return-to-rest positioning and reducing stick-slip conditions. The design supports smooth operation through a range of temperatures and moisture conditions typical of highway and off-road service. Standard compatibility with drum brake configurations in class 7 and 8 trucks makes it a common preventive-maintenance upgrade for fleets prioritizing predictable stopping power and long service life for braking components.
