ABSTRACT:
A vacuum assisted booster having an input rod with a thrust member thereon, an output rod with a piston head thereon, and an elastomeric disc located between the thrust member and the piston head. The piston head has an axial bore therein and the thrust member has an axial projection that extends through the elastomeric disc into the bore. The projection is anchored to the piston head by a cap fitted to the head and which allows some forward movement of the thrust member to apply a load to the elastomeric disc but limits axial separation of the piston head and thrust member on the return stroke.
