A single cylinder (11) is supported within the column. A first braking circuit (C1) operates left and right rear brakes (36L, 36R) and a second braking circuit( C2) operates a cardan brake (39), characterised in that braking circuits (C1, C2) are connected to the single cylinder (11) mounted on the steering column and wherein said steering column comprises a valve unit (5d), so that the left and right rear brakes (36L, 36R, 39) are operable by two pedals (9, 10). |
