A frictionally engaging device, such as a disc brake, includes a first and a second friction element which engage one another as the device is operated to reduce the extent of and/or eliminate relative movement between these elements. The first element consists of an organically bonded friction material suffering relatively more pronounced wear, and the second element is made of a metallic material, especially iron, which suffers lesser wear in operation. The extent of wear of the first element is reduced by applying a coating of a particulate material, especially such deposited by high kinetic energy impacting of the particles, on the frictional surface of the second element which cooperates with the first element. The coating advantageously contains metals, such as cobalt, chromium and/or nickel, and/or metal carbides, especially those of tungsten and chromium.

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.
