摘要

A composition brake shoe for a railway vehicle for reconditioning a wheel tread surface during normal braking comprising: (a) a backing plate having a stirrup, (b) a first friction type composition material formed into a brake shoe having a predetermined shape; (c) a brake surface for engaging a wheel tread having a configuration formed in said brake shoe and having a predetermined surface area; and (d) a second friction type material formed as at least one discrete insert, having a predetermined shape and molded into said first friction type composition material, said second friction type material initially being completely embedded within said first friction type composition material, one surface of said at least one discrete insert being disposed facing said predetermined surface area of said brake surface of said composition brake shoe, said at least one discrete insert of said second friction material is bonded to said backing plate.
