Abstract
A brake booster for an automobile which includes a reaction disc plate disposed within a central bore of a power piston, one surface of the reaction disc plate contacting the cylindrical member and an opposite side surface contacting force transmitting means wherein one side surface of the reaction disc plate includes a rounded surface complementary to a rounded surface provided on the cylindrical member. A combined cylindrical member and reaction disc plate are utilized such that no space or gap is formed between the cylindrical member and reaction plate so as to shorten the length of the cylindrical member and decrease the time necessary for initiation of brake operation of the brake booster.
