Product type
Trailer brake drums are cylindrical components that house the braking mechanism for trailers. They are typically made of cast iron or aluminum, designed to withstand high temperatures and pressures generated during braking. When the brake shoes press against the inner surface of the drum, friction is created, slowing down or stopping the trailer's movement.
