Abstract
A method and a system of a friction device for a wheel may include a backing plate and a friction material disposed on the backing plate to form a brake surface to engage a surface of the wheel. The friction material extends between a first end and a second end along a central longitudinal axis, and between a rim side and a flange side. A void is disposed within the friction material and extends from the brake surface a distance into the friction material. The void forms an opening of the brake surface of the friction material.
