Abstract
A disk brake is configured as a brake apparatus provided with an electric parking brake function capable of holding braking of a vehicle by driving an electric actuator. A parking brake control apparatus, which controls the electric actuator, actuates the electric actuator so as to release holding of the braking upon determining that the vehicle is in a running state. More specifically, if a speed of the vehicle is maintained at a speed higher than 0 km/h for a predetermined time period, the parking brake control apparatus actuates a rotation/linear motion conversion mechanism by the electric actuator so as to release the holding of the piston of the disk brake.
