ABSTRACT:
A brake booster having a movable partition (6) through which an output force is carried through a first reaction device (24,25) to a brake system in response to an input force applied to a brake rod (9). A second reaction device (29-34) is located between the brake rod (9) and the first reaction device (24,25) and includes a first spring (34) that is compressed by a predetermined reaction force and the input force such that any further input force is carried through a second spring (32) into the movable partition (6) to provide and additional force in the development of an output farce corresponding to a desired a brake application.
