Abstract
In a disk brake apparatus of the present invention, it is determined whether a centering operation should be performed, and operation conditions for the centering operation (the length of the interval and the number of the operations) are set, according to a change of deformation of a disk rotor by heat release over time. When the centering operation is performed, a solenoid is actuated to perform the centering operation according to the set operation conditions. The centering operation is an operation of moving a pair of brake pads (2) and (3) into contact with the disk rotor (1) and then separating the pads from the disk rotor during a cooling process while a vehicle is running.
Claims15
A disk brake apparatus, wherein
- a brake pad is moved by actuating an actuator so that the brake pad is pressed against a disk rotor to generate a braking force;
- and
- the disk brake apparatus comprises a controller adapted to control the actuator to cause the brake pad to be moved into contact with the disk rotor, and then be separated from the disk rotor so that a pad clearance is adjusted according to a change of deformation of the disk rotor by heat release over time after the braking force is generated.
