The breaking device which is intended in particular for brake rails on shunting yards has a retarder beam whose surface (2) which presses against a wagon wheel consists of at least two materials with different coefficients of friction. As a result, a large reduction in the generation of noise is achieved. Advantageously, the retarder beam is composed of layers of transversely arranged elements (3, 4), there being an alternation between one of these elements consisting of one material and elements adjacent thereto consisting of the other material. <IMAGE>
