Abstract
Provided is a vehicular brake apparatus capable of suppressing the occurrence of pedal shock. In this vehicular brake apparatus, a master cylinder forms a second hydraulic chamber neighboring to a first hydraulic chamber through a seal member. The seal member is arranged at a position facing the first hydraulic chamber and the second hydraulic chamber to be movable in the axial direction relative to the master cylinder. A first hydraulic pressure generating portion executes a movement restriction hydraulic pressure control such that when the operation information obtained by the operation information obtaining portion indicates that the brake operating member is not operated, the first hydraulic pressure which is higher than the second hydraulic pressure is generated in advance and consecutively, the larger a value relating to an operating amount in the operation information obtained by the operation information obtaining portion, the higher the first hydraulic pressure is generated.
