Abstract
An integrated master cylinder and vacuum power booster provides a brake apply system wherein the master cylinder and power booster are structurally and functionally combined together to provide a uniquely packaged system. The integral system includes a master cylinder housing having a tubular extension that carries the power booster housing with at least two operating chambers. A power piston is movable by variable pressure levels between the two chambers. The power piston cooperates with a translating element carried within the tubular extension to communicate sliding movement of the power piston to the master cylinder piston.
