Terex Bushing Assy-S-Cam

Terex Bushing Assy-S-Cam

This is a replacement camshaft bushing for the S-cam air brake system found on Terex front discharge concrete mixers. The S-cam shaft rotates within this bushing to spread the brake shoes against the drum; over time, the original bushing can wear out, leading to excessive play, poor braking performance, and uneven shoe wear. Replacing a worn S-cam bushing is a critical maintenance task to restore proper brake function and ensure vehicle safety. This component is a direct replacement for the bushing in Meritor 'P' and 'Q' type drive axle brake assemblies.
