Abstract
First hydraulic-pressure supply piping extended from an accumulator is connected to a first supply port (that is, to a second pressure chamber) of a cylinder, and to second hydraulic-pressure delivery piping of an ABS via third hydraulic-pressure supply piping having a third linear valve. When the braking hydraulic pressure Pf is reduced in the ABS, the degree and the period of time that the third linear valve is opened are set according to the amount of fluid discharged from the second hydraulic-pressure delivery piping to a reservoir tank through a pressure-reducing valve so that a certain amount of fluid is returned from the first hydraulic-pressure supply piping to the second hydraulic-pressure delivery piping via the third hydraulic-pressure supply piping.
