Abstract
A brake actuator has a force applying device actuated by a rotary actuator shaft and arranged to separate opposed tappets to actuate braking elements. Each tappet includes a pair of threadedly engaged members which are relatively rotatable to enable the length of each tappet to be adjusted. An adjuster control device is operable to vary the length of one of the tappets and a transmission device interconnects the tappets to effect a corresponding variation in length of the other tappet. The transmission device, a ring gear, lies within the actuator housing at a location adjacent the axially inner end of the force applying device and cooperates with both tappets to transmit adjusting movement of one tappet to the other.
