Abstract
A parking brake system having a lock mechanism provided within a casing to the rear of a parking piston that provides a parking brake mode by forward movement of a lock mechanism in response to the action of a parking control fluid pressure. The lock mechanism responds to forward movement of the parking piston to mechanically lock the parking piston at a forward position and unlocking in response to the action of a parking release control fluid pressure. The lock mechanism includes a lock piston that is to the rear of the parking piston having an axis orthogonal to the axis of the parking piston. This enables an automatic parking brake mode to be obtained by a simple structure without consuming power.
