Brake Drum
Mack

This brake drum is designed to deliver consistent braking torque under demanding duty cycles, with a robust casting and a friction-ready surface that accommodates standard brake shoes. The drum’s thermal stability and dimensional integrity help maintain even wear and reliable stopping performance during long hauls and heavy braking events. Proper fitment and hub alignment are essential to minimize lateral runout, reduce rider roughness, and extend the life of the braking system. Routine inspection for cracks, scoring, or over-heating signs ensures continued reliability. Replacing worn drums promptly helps protect wheel components and maintain predictable stopping distances in all operating conditions. Source One Parts Center.
