(57) Abstract Application of the brake the pedal operational hydrostatics master cylinder (31) through one actuator (5) at least in the brake equipment which is controlled electrically by the use of the electric control actuator (5,6), it is jointed to the brake (12). In order for the valve to open in order to apply hydrostatics pressure on both parties of the nosewheel brake (1,2) the nosewheel brake by the liquid pressure making communicate when breaking down of the electric apparatus (15a and 15b, 60), it can provide the 1st valve (7) which usually is opened. While operating of the normal brake, it is closed in order to prevent the fact that it can add to the brake hydrostatics pressure it to be possible the fact that the 2nd valve (44) which is opened normal is provided, you open the valve, automatically when breaking down of the electric apparatus (15a and 15b, 60).
