It has a 16.5-inch diameter braking surface, 7-inch wide brake shoes, and a 10-bolt pattern. Over time, brake drums wear down from friction and heat; if the diameter exceeds the maximum wear limit of 16.62 inches or if cracks, scoring, or vibration appear, the drum should be replaced. This drum is a common replacement part for many Class 8 commercial vehicles with 16.5x7-inch brakes.
