Abstract
In an electric brake system with at least an electric wheel brake mechanism having a pair of brake friction pads to produce a braking force based on a brake manipulated variable, and a brake friction pad thrust sensor detecting a pressure of either one of the brake friction pad pair against a disk rotor, an electric brake control unit causing a temporary movement of the brake friction pad pair into contact with the disk rotor when a predetermined time period has expired from a time when a brake pedal has been recovered to an inoperative state. In the system, a position of the brake friction pad pair, at which the pressure becomes greater than a predetermined threshold value during the temporary movement of the brake friction pad pair into contact with the disk rotor, is detected or determined as a braking initiation position.
