Abstract

The invention relates to master cylinder and actuator assemblies in which a push rod (5) connected to the actuator (2) extends forwardly through a vehicle mounting member (3) and is engageable at its forward end with a piston (9), there normally being a clearance between the push rod and the piston in their inoperative positions. Such assemblies suffer from the disadvantage that a desired working clearance is difficult to attain due to manufacturing tolerances. Embodiments of the present invention overcome that disadvantage and provide an assembly which includes a lateral projection (10) on the push rod (5), which projection limits rearward movement of the push rod relative to the mounting member (3). <IMAGE>
