ABSTRACT:
A braking apparatus for a motor vehicle equipped with a master cylinder and a wheel cylinder. The apparatus further includes a pump coupled to a reservoir tank to suck a braking liquid from the reservoir tank and pressurize and discharge the sucked braking liquid when a slip of the wheel occurs at the time of driving the wheel, a pressure adjusting valve provided in a pipe coupling a discharge side of the pump to the reservoir tank and arranged to be openable to restrict the discharge pressure of the pump to a predetermined value, and a change-over valve for establishing a communication between the discharge side of the pump and the wheel cylinder when a slip of the wheel occurs at the time of driving the wheel and for establishing a communication between the master cylinder and the wheel cylinder when the slip does not occur. The apparatus controls a braking pressure adjusting device provided between the change-over valve and the wheel cylinder for adjusting the braking pressure to be applied to the wheel cylinder when a drive slip of the wheel occurs, thereby suppressing the drive slip. This arrangement allows the size-reduction of the apparatus and the suppression of generation of operating sound.
