Abstract
A brake shoe includes a backing plate configured to interface with a brake head of a vehicle. The backing plate includes a main body and a flange attached to the main body and configured to align the brake shoe on a wheel of the vehicle. The brake shoe also includes a composition friction material disposed on the backing plate, which defines a brake surface for engaging the wheel. The brake shoe may have one or more dimensional characteristics for facilitating alignment of the brake shoe with the wheel, e.g., a ratio of a shortest horizontal distance to a shortest vertical distance of the brake shoe may be at least 1.07 and no more than 1.25, or a ratio of a length of the main body of the brake shoe to a length of the flange may be at least 1.3 and not more than 1.7.
