Webb Wheel Products' 66764F is a lightweight brake drum with venting for increased airflow designed for use in trailer applications.
The drum was engineered specifically for 20,000-pound trailer axles and is designed to run cooler with Webb’s Cool Running Technology vents. Aerodynamic trailer skirts can increase break temperatures by reducing airflow beneath a trailer, according to Webb. The increased heat reduces braking performance and accelerates brake drum and lining wear.
