A brake shoe assembly for a drum brake, said brake shoe assembly being of single-piece construction and including a brake shoe of generally circular form having two separate and opposed ends, and defining a pair of friction lining mounting sections disposed on opposite sides of said brake shoe which have a T-shaped cross-sectional form defining an arcuate, radially outer platform for mounting a friction lining and a radially inwardly extending web, the cross-sectional form of each said lining mounting section causing said sections to have substantial rigidity in the plane of said web, said brake shoe including a recess formed in said web between said lining mounting sections, said recess being open inwardly and extending a substantial portion of the full depth of said web and acting as a hinge which facilitates pivoting movement of said lining mounting sections to alter the separation between said brake ends between a brake operative condition in which in use, said friction lining engages a braking surface of a drum to which the brake shoe assembly is fitted, and a brake inoperative condition in which there is no such engagement, a backing plate depending from said brake shoe in the region of said recess for mounting said brake shoe to a brake shoe assembly support.
