Abstract

A reaction structure of a brake booster comprises a deformable reaction disc with a peripheral edge rounded at a radius off corresonding to the radius of the rounded edge of a larger bore receiving the reaction disc. On a brake operation, the reaction disc is coaxially compressed between a second valve element interposed with a clearance thereto and connected to an input pushing rod and a power output rod, thereby resulting in a definite jumping value without indefinite delay of output power rise.
