A hydraulic braking system of the split type including a fluid pressure control device which is adapted to reduce or stop the rate of increase of an output fluid pressure to wheel cylinders when a certain critical level is reached by an input fluid pressure delivered from a master cylinder, wherein the rates of increase of such critical level and the output fluid pressure if higher than the critical level are lowered when one of the split hydraulic circuits of the braking system fails or, if the rate of increase of the output fluid pressure higher than the critical level, only the critical level of the pressure is lowered.
