A handbrake assembly (110) includes a handbrake lever (112) pivotally mounted to a bracket (14, Fig. 1) for movement between brake-off and brake-on positions; and a lock mechanism (120) releasably holding the lever in the brake-on position. The lock mechanism is released by a release button (122) mounted to the lever, and a linkage (124) transmitting movement of the button to the lock mechanism. The linkage includes a coupling arrangement having a coupling member (152) movable between an operative position (Fig. 2) in which movement of the release button is transmitted to the lock mechanism, and an inoperative position (as shown) in which movement of the release button is not transmitted to the lock mechanism. The assembly has an actuator (154) for moving the coupling member between the operative and inoperative positions. An alternative arrangement uses a stepper motor (272, Fig. 5) within linkage 224.
