The invention belongs to the aviation technology. A hydraulic braking system comprises double control of helicopter undercarriage wheel braking. The control device for wheel braking of the helicopterundercarriage comprises two operating levers (1, 1') of control buttons (2, 2') connected through operating steel cables (3, 4), and the operating steel cables are connected with wheels of the undercarriage. The control cable (3, 4) is equipped with a tension device (15) consisting of a body (16) closed by a plug (17), in which a sleeve (18) of a piston (19) and a cable (5) with a fixed joint (20)are inserted. The steel cable (3, 4) is further equipped with a reinforcing device (25) comprising a body (31) of the load reducing cylinder, inside which a rod (33) is arranged, isolated from the body (31) by a spring (34). In addition, the steel cable (3, 4) comprises a unit (8) fixed on the cab floor, consisting of an internal core (10) and a body (9), the steel cable (5) passing through the core of the body, the steel cable being fixed by stops on both sides of the body (9).
