ABSTRACT:
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.
