Abstract
A method of manufacturing a tandem brake booster wherein a rearwall is derived from the separation plate of a single brake booster. The separation plate is modified by creating a passageway therethrough and using splines on the hub which are mated with keyways in a cylindrical body that extends from a front movable wall to assure that passages between the resulting front and rear chambers are aligned. A return spring holds a seal between the cylindrical body and hub to assure cross communication does not occur between the passageways. Thereafter, any operational pressure differential created during a brake application is directed into the development of an output force to effect a brake application.
