Abstract
A novel composite brake drum with a shell and a drum liner that includes one or more mid-positioned squealer bands that are roughly in line with the ribs of the brake shoes. This places the most rigid part of the brake drum and the location of greatest heat sink over the most rigid portion of the brake shoes, which is also the position of greatest heat input. The axial cooling fins radiating from the squealer band aid in dissipating the heat from friction generated during the braking cycle.
