A brake drum may be the proper size to fit the wheel end, but depending on the vehicle's application, other product characteristics are important to consider to ensure optimum performance and operating costs.
A video, Proper Brake Drum Selection, available at www.webbwheel.com, explains how braking events affect a brake drum depending on vehicle speed, total weight and rate of brake deceleration.
It gives the viewer enough information to determine the best brake drum for their operation. A test can be taken after viewing the video to certify that the material has been understood.
For the popular 16.5x7-inch brake size with 8.78-inch pilot rated to 23,000 pounds GAWR, for instance, Webb offers the following choices in brake drums, all manufactured in the U.S from high strength gray iron.
