1. A brake control apparatus comprising:
a first pressure-applying section connected through a first oil passage to a wheel cylinder, and configured to apply hydraulic pressure to the wheel cylinder; a pump provided separately from the first pressure-applying section, and configured to apply hydraulic pressure to the wheel cylinder; a communication valve provided on a second oil passage which connects the first oil passage with the pump; a backflow passage connecting a suction side of the pump with a portion between the pump and the communication valve in the second oil passage, the backflow passage being connected with a pressure-reducing oil passage; a pressure-regulating valve provided on the backflow passage; and a control unit configured to control the pump, the communication valve and the pressure-regulating valve, wherein the control unit is configured
to attain a first state that causes the first pressure-applying section to apply hydraulic pressure to the wheel cylinder, and a second state that causes the pump to apply hydraulic pressure to the wheel cylinder by driving the pump and at least one of the communication valve and the pressure-regulating valve in an opening direction, andto actuate the at least one of the communication valve and the pressure-regulating valve with a delay relative to an actuation of the pump, when switching from the first state to the second state. |
