Abstract
In a brake control apparatus that controls braking forces which are applied to wheels based on the pressure of the hydraulic fluid, when the pressure detected by a control pressure sensor (73) is equal to or higher than a predetermined value while a partition valve (60) is closed, a master cut valve (64) is closed to suppress an increase in the pressure in a first passage (45) in a first hydraulic circuit (37), to which the control pressure sensor (73) is connected. Alternatively, the control pressure sensor (73) is protected against overpressure by opening the outlet valve (56,57) or the pressure-decreasing valve (67).
