Abstract
This invention relates to a brake booster for automotive vehicles including a housing, a brake master cylinder connected to the housing and a diaphragm power piston dividing the housing into first and second fluid chambers and having a retracted position defined by abutment with the housing and a control valve mechanism for the diaphragm power piston to control the pressure differential between the chambers in response to brake pedal movement axially relative to the power piston, wherein at least two bolts extend from the master cylinder outside of and past the housing toward a dash board of a vehicle for installation. A brake reactional force is transmitted by the bolts from the master cylinder directly to the dash board bypassing the housing, the thickness of the sheet metal forming the housing being thus calculated to be a lesser gauge for weight decreasing purposes than would otherwise be required.
