ABSTRACT:
A shield for a brake actuator has a bore closely surrounding a piston rod which is welded to a yoke. The shield is formed with a plurality of slits that allow portions of the shield between the slits to bend radially outwardly and allow the yoke to move through the bore. Thus, the invention allows the use of a yoke which is welded to a piston rod, and also allows the use of a shield which closely surrounds the piston rod.
