    • PURPOSE:To obtain constant braking deceleration with the same pedal treading force by providing a throttling means which controls fluid for driving a power booster and controlling degree of throttling for the throttling means according to the car weight. CONSTITUTION:Car weight is detected through publicity known weight detection means and the highest oil pressure required for generation of the largest braking force appropriate to said weight is obtained from characteristic data prepared in advance. A motor 23 of a pressure setting part 16 is driven for control on the basis of the highest oil pressure thus obtained. By driving control of the motor 23, the position of a piston 11c of a pressure control part 11 is controlled through an arm 20, that is, the piston 11c is displaced leftward as the car weight is increased. When the piston 11c is displaced leftward, since the oil flow from an oil suppy pipe 13 to a return pipe 14 is throttled, the pressure in a chamber A is increased. With this increase, the pressure in chambers (b), (c) of a booster 6 is increased.
