Dust Shield
Bendix

Dust shields are essential protective barriers designed to shield wheel-end and brake-area components from abrasive particulate matter encountered in harsh road conditions. By deflecting dust, dirt, and small stones away from seals, bearings, and moving hardware, these shields help minimize wear, reduce contamination-induced corrosion, and extend service life for critical interfaces. In practice, they contribute to more consistent braking performance by preserving seal integrity and preventing debris from interfering with caliper pistons, rotor faces, or linkage mechanisms. The shield’s mounting features allow rapid installation and straightforward replacement during routine maintenance or after rotor servicing. Its inclusion in the 41393 category places it firmly within the protective-baffle and dust-management subset of heavy-truck braking components, while the VMRS code 013-001-114 identifies its function as a protective accessory that supports reliability and uptime in demanding operating environments.
