The latest advanced brake drum design from Webb Wheel Products incorporates their patented CRT (Cool Running Technology) vents that maximize airflow into the wheel end, managing heat better than similar weight brake drums, according to the company. 

The Webb 56864B brake drum has been optimized by using Finite Element Analysis and real-world data to run 10 percent cooler and last 10 percent longer in standard duty 23K drive and trailer applications.

With the heat transfer efficiency of the 56864B brake drum, maintenance costs will be reduced and brakes will perform better, the company says. 

Technology added to trailers to enhance aerodynamics, such as side skirts, can also reduce crosswind and straight-line airflow below the trailer resulting in increases in brake temperature. This added heat reduces braking performance and accelerates brake drum and lining wear. The  design of the Webb 56864B brake drum with CRT vents is a solution to mitigating the effects on brakes from the deflected air flow around wheel-ends that may be a result of adding skirts or other similar bolt-on devices.

Webb brake drums are designed, cast, and machined in the USA.
