The present invention is directed to a brake shoe adapted for use in a braking mechanism that comprises a support member and a substantially metal free brake pad disposed on the support member. The brake pad may be composed of polymerized urethane as a major constituent thereof. More particularly, the brake pad may be composed of a mixture including urethane, a urethane reactant and a urethane curing agent. The durometer hardness of the brake pad may be between 80 and 95 on the A-scale. The support member may include a connector and a base plate, and the brake pad may be formed as an integral one-piece molded construction with the base plate being embedded in the brake pad. The brake pad may have a contact surface that is contoured so that the brake pad has varying thickness to differentially contact a moving surface. The present invention also provides a caliper-type braking mechanism having a brake shoe including a brake pad disposed thereon, wherein the brake shoe is adapted to be secured to a free end of a brake arm of the caliper-type braking mechanism. Additionally, the present invention is directed to a method of fabricating a brake shoe adapted for use in a caliper-type braking mechanism.
