GARBAGE TRUCK DRUM

This is a heavy-duty cast brake drum for air brake systems, sized 16.5 inches in diameter by 8.625 inches wide. It is balanced and features 10 bolt holes with a 0.94‑inch diameter, making it suitable for severe‑duty vocational trucks like garbage trucks. The drum is replaced when the braking surface wears beyond the maximum discard diameter, shows heat cracking, or becomes out‑of‑round to maintain safe stopping performance.
