Accuride says its newest brake drum – the Gunite Optimum Lightweight Drum — is designed to be an optimum balance between durability and thermal capability, providing the performance of full cast drums but saving as much as 170 lb on a typical tractor/trailer combo.
“During two years of field testing, fleets reported longer drum life without increased lining wear,” says Dr. Omar
Fakhoury, Gunite general manager (the company is an Accuride subsidiary).
Collectively, drum life expectancy was shown to increase by 50-75 percent for steer-axle applications, 20-50 percent on drive axles, and 20-40 percent for trailer-axle applications. Field testing also showed the new drums to be effective against brake drum “squeal” vs. lightweight shell composite brake drums.
