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.

Integral brake apply system

A guide rod extends longitudinally through the power piston of a vacuum power booster providing lateral support thereto and tying the master cylinder housing to a bracket on the rear of the power booster housing. A guide rod provides a means of positively laterally supporting the power piston, control valve and push rods of the power booster thereby providing the ability to reduce the relative supportive strength of the housing, housing divider and piston bearings.

Power booster with guided power piston

A brush holder body for a dynamoelectric machine comprising a molded body, integrated cantilever fingers molded into the body, the cantilever fingers extending radially inward from distal portions of the body, the cantilever fingers having a normal position into which they are molded extending at an angle to a plane of a commutator clearance opening the angle having a direction extending away from a motor armature position, wherein the cantilever finger is flexible and upon receipt of a force, flex in the direction of the armature, wherein the brush holder also comprises a snap feature for retaining the cantilever finger in a second position in which the cantilever finger prevents movement of a brush into the commutator clearance opening, wherein in the normal position, the cantilever finger allows movement of the brush into the commutator clearance opening and the cantilever finger does not contact a commutator of the dynamoelectric machine.
