| A parking brake system is provided in which a parking brake state is obtained by forward movement of a parking piston in response to the action of a parking control fluid pressure, and a forward operating state of the parking piston is mechanically locked by a lock mechanism. Moreover, an input member of a brake mechanism and the parking piston are connected by a coupling linkage. A lock piston of the lock mechanism moves toward one side in the axial direction when the parking piston moves forward, and a locking part provided at one end of the lock piston engages from the rear with a retaining part provided on a middle section of the coupling linkage while straddling the middle section of the coupling. This enables an automatic parking brake state to be obtained by a simple structure without consuming power. | ||||||

| A disc or drum brake fluid pressure actuator incorporates a lock actuator strut acting on an inner part of a telescopic piston assembly, of which the inner and outer parts are normally rendered effectively unitary by pre-stressed spring which can, however, deflect under excess pressure to permit extension of the lock actuator strut when it is desired to operate the strut for parking purposes. An hydraulic control system for operating the actuator is also described and illustrated. | ||||||

| In a drum or disc brake having a locking means for holding the friction elements applied mechanically for parking etc., the locking means is operatively connected to a friction element independently of the normal actuation means. The locking means preferably comprises an extensible strut normally free to extend and contract to follow up friction element movements. A clutch is operative to lock the strut in extended condition to apply the lock and is releasable by means of a pressure operated clutch release motor having a piston directly engageable with one of the strut members. To release the lock the piston displaces the said strut member to disengage the friction clutch, whereafter the strut can contract to release the brake. These arrangements therefore cut out lost motion which takes place if (a) the lock acts on a brake actuating linkage instead of on a friction element; or (b) if the clutch release motor acts on the clutch mechanism instead of on the strut itself.
