Original SINOTRUK HOWO A7 T7H Ac16 SHACMAN FAW DONGFENG FOTON CAMC BEIBENZ Spare Parts Rear Brake Drum WG9231343006 Rear Brake Drum (rear Brake Hub)

The WG9231343006 Rear Brake Drum is a core friction component of the drum brake system installed on the rear wheels of SINOTRUK HOWO, SITRAK C7H/G7, and Steyr-series heavy-duty commercial vehicles. As the rotating element that interfaces with the brake shoes, it converts kinetic energy into thermal energy through friction, enabling controlled deceleration and full stops under extreme load conditions.

Manufactured from high-grade gray cast iron (HT250 or higher), this brake drum delivers excellent thermal conductivity, wear resistance, and structural integrity, making it ideal for long-haul freight, mining operations, and construction transport where frequent and intense braking occurs.
