Abstract
A variable force rate vacuum booster including a reaction disk having an input surface and an output surface, the reaction disk being formed from a deformable material, an input rod position relative to the reaction disk to apply an input force to the input surface of the reaction disk, an output rod having a reaction surface generally engaged with the output surface of the reaction disk, the output rod defining a bore therein, and a plunger positioned in the bore and biased out of the bore by a biasing force, the plunger being adapted to resist deformation of the reaction disk into the bore until the input force reaches a threshold value.
