It provides the friction surface that the brake shoes press against to slow the vehicle. When the drum wears past its maximum diameter, develops cracks, or shows hot spots, it must be replaced to maintain safe braking performance. The 16.5‑inch diameter and 7‑inch width match common air brake systems on auxiliary axles.
