Type of brake mechanisms – drum, with one working cylinder and the self-established ("floating") blocks, with the device for automatic maintenance of a constant optimum gap between blocks and a drum (1,4–1,7 mm). Brake drums are cast from aluminum alloy with the pig-iron sleeves which are filled in in them.
