Brake managements of cars of fashion. 2141-01, 21412-01, 214122, 214123 and fashion. 2335, 23352, 233522, 233523 have almost identical design and differ only with length, a configuration and the number of some pipelines, and also characteristics of regulators of pressure in a hydraulic actuator of back brakes and way of fastening of a cover of a back cable of the manual drive of brakes to boards of back brake mechanisms. In this regard the description of brake management is provided in relation to cars of fashion. 2141-01, 21412-01, 214122, 214123. Original elements of brake management of cars of fashion. 2335, 23352, 233522, 233523 are described separately.
