Abstract

A brake shoe assembly is composed of a carrier plate, a friction material lining secured to the carrier plate and the brake-shoe spring. The brake-shoe spring comprises between its legs a loop-shaped portion which is supported in a recess in the brake shoe, this recess being open towards the edge of the brake shoe. Arranged at the open recess is a projection which extends into the loop-shaped portion between two convolutions of the brake-shoe spring. The two convolutions are interconnected by a wire portion disposed at the area of the legs.
