Patent ID: 8333267

Claim:
A disk brake for a vehicle, the disk brake comprising: a disk rotating together with a wheel of the vehicle; a friction pad which makes contact with a side surface of the disk to generate braking force; a wedge member to which the friction pad is attached; a drive motor which generates a driving force to move the wedge member toward the disk, said drive motor includes an axis about which rotational motion is provided; a power transmission part which shifts the rotational motion of the drive motor into a linear motion of the wedge member; a pad compensation part mechanically coupled to said drive motor, said pad compensation part maintains a gap between the friction pad and the disk uniform by displacing said drive motor; and a manual release part installed in the pad compensation part such that contact between the friction pad and the disk is manually released when the friction pad and the disk are locked in a braking state due to friction between the friction pad and the disk, wherein said pad compensation part includes a driving part which displaces said drive motor relative to said driving part in a direction parallel to said axis.
