A characteristic changing device is adopted in the inventive brake control system for the vehicle. The characteristic changing device sets a differential pressure between a first brake hydraulic pressure which is applied to wheel cylinders and a second brake hydraulic pressure which is generated by a master cylinder so that the first brake hydraulic pressure is higher than the second hydraulic pressure when the second brake hydraulic pressure is reduced. Due to the differential pressure set as described above, the first brake hydraulic pressure enough to exhibit effective braking force is kept even if the second brake hydraulic pressure is reduced.

1. A brake control apparatus for a vehicle, comprising:an operating member to cause brake hydraulic pressure to generate; a hydraulic pressure generating source for generating the brake hydraulic pressure in response to an operation of the operating member; a wheel braking force generation member for providing braking force to at least one wheel of the vehicle by receiving the brake hydraulic pressure from the hydraulic pressure generating source with the wheel braking force generation member; a conduit which connects the hydraulic pressure generating source with the wheel braking generation force generation member; and characteristic changing means for reducing the brake hydraulic pressure applied to the wheel braking force generation member at a lower rate than a variation rate of a return movement of the operating member during a portion of a time when the operating member is operated so as to reduce the brake hydraulic pressure in the hydraulic pressure generating source, and for increasing the brake hydraulic pressure applied to the wheel braking force generation member at the same rate as a variation rate of a depressing movement of the operating member so that a constant increasing rate pressure is applied to the wheel braking force generation member when the operating member is operated so as to constantly increase the brake hydraulic pressure in the hydraulic pressure generating source.
