An electric brake actuator ( 14 ), including a rotatable member ( 21 ) and electric drive means ( 34 ) for driving the rotatable member ( 21 ) to rotate. The rotatable member ( 21 ) is arranged for engagement with a continuous cable ( 18 ) that in use extends between and in connection with a pair of brake assemblies ( 12 ) that are operable when actuated to apply a braking load to brake a wheel associated with each respective brake assembly. The rotatable member ( 21 ) is arranged such that it is operable to pull the cable ( 18 ) on each side of the rotatable member ( 21 ) upon rotation of the rotatable member ( 21 ) in a first direction, for actuation of the brake assemblies ( 12 ), and to extend the cable ( 18 ) on each side of the rotatable member ( 21 ) upon rotation of the rotatable member ( 21 ) in a second and reverse direction. |
