Abstract
A parking brake of a work vehicle has a piston near the wheel relative to an end plate in an axial direction parallel to a rotation axis of the drive shaft to move in the axial direction, a hub between the end plate and the piston in the axial direction to be connected to the drive shaft, a cylinder disposed outwardly from the hub in a radial direction relative to the rotation axis, a disk supported by the hub in an inner space defined by the end plate, the piston, the hub, and the cylinder, a separator supported by the cylinder, next to the disk in the inner space, and moved by the piston in the axial direction, a first passage connecting the inner space and an outer space, and a second passage provided outwardly from the first passage in the radial direction to connect the inner and outer spaces.
