Webb Wheel has added a new training video with an associated tech certification test to the Training Toolbox on its website. The new Proper Brake Drum Selection video illustrates clearly how braking events affect a brake drum depending on vehicle speed and total weight as well as the rate of brake deceleration; and it explains how different drum designs manage the amount of heat generated at each stop.
Because of these variables, vehicle use is an important factor in choosing the right drum for a particular application and the video helps in determining the proper designs to ensure the best brake performance and lowest cost of maintenance. After viewing the video, a test can be taken online to certify that the technician understands brake-drum differences for the vehicles they maintain.
All Webb Training Toolbox videos, files and certification tests can be accessed online. Technicians can also review and test themselves on correct wheel-end installation procedures for different hub mounting systems. There’s also a downloadable PDF available that addresses the potential causes of the two most common warranty returns for brake drums — out-of-round and cracked. Videos can be viewed in English, Spanish or French.
