TruTurn Brake Drums

TruTurn® Brake Drums are precision-machined inside and out, which improves drum strength by eliminating the need for weld-on weights and balance cuts. 

TruTurn brake drums are constructed using ConMet’s “turned-to-balance” machining process, which improves drum strength by eliminating the need for weld-on weights and balance cuts. Not only does this process make the drums stronger, but it creates other advantages such as uniform thermal expansion for reduced brake pulsing, and improved heat transfer, so the drum and brake linings stay cooler. Braking force is more evenly distributed, and occurrences of vibration and “judder” are minimized. With each stop, TruTurn brake drums maintain lower temperatures, maximize durability, minimize wear, and improve brake performance.
