This heavy truck brake drum is a core component of the braking system for trucks and trailers. It is integrally cast from high-strength cast iron with high density and excellent wear resistance and heat dissipation. The precisely machined inner working surface ensures smooth contact and stable braking performance. With heat treatment, it resists thermal cracking and deformation under heavy loads and frequent braking on long downhill roads. The accurate flange holes allow easy installation. It is an ideal replacement for worn, grooved or cracked old brake drums to guarantee reliable braking safety for truck and trailer maintenance.
