A brake ( ) having particular application for a linear motion device ( ) includes a channel ( ) secured to the base plate ( ) in which a body ( ) secured to the sliding plate ( ) partially extends. A tape seal ( ) of the channel ( ) extends through a slot ( ) formed in the body ( ) so that the calipers ( ) moveably mounted to the body ( ) are located within a hollow interior of the channel ( ). The calipers ( ) include cylindrical carriers ( ) slideably received in cross bores ( ) in the body ( ) and are biased to a disengaged position by a spring ( ) sandwiched between a snap ring ( ) in the cross bore ( ) and the carrier ( ). A diametric groove ( ) is formed on the inner axial end of the carrier ( ) and slideably receives a side ( ) of an actuator element ( ) which extends in a non-axial direction. The actuator element ( ) is moveably mounted in an axial through bore ( ) by first and second supports ( ) secured to the axial ends and including an elastomeric seal ( ) to compliantly suspend the actuator element ( ) in the through bore ( ). The actuator element ( ) is moved in a first axial direction by a spring ( ) and in the opposite axial direction by fluid pressure in a fluid chamber.
